OPINION OF THE COURT
KAUFFMAN, Justice.After a non-jury trial in the Court of Common Pleas of Franklin County, appellant, Glenn D. Council, was convicted of two counts of robbery. The Superior Court unanimously affirmed appellant’s judgments of sentence in a per curiam order. We granted allocatur and now affirm.
Appellant contends that the trial evidence does not support his convictions. We disagree. The record shows that on October 7, 1975, at approximately 5:00 p. m., a black male, wearing a dark jacket and a knit cap, his face partially covered with a pink and white towel, ran into Smith’s Grocery Store in Fayetteville, Pennsylvania. He first requested toothache medicine from the owner, Mrs. Edna Smith, and then forced her to place the sixty-five dollars in her cash register, in denominations of one and five dollar bills, on the store counter. Mr. Marion Cubeta then entered the store and the robber drew a gun and ordered him to “freeze.” After ripping out a candy case in an unsuccessful attempt to find more money, the robber patted Cubeta down, turned out his pockets, and ordered him to put all his money-some fifty cents-on the counter. The robber then scooped the money off the counter, warned Smith and Cubeta to remain silent, and fled.
In the early morning hours of October 8, 1975, after obtaining a search warrant for appellant’s hotel room and car,1 the police seized, inter alia, a dark jacket, a knit cap, a toy pistol, a green bag containing sixty-two dollars in de*437nominations of one and five dollar bills, and a pink and white towel.2
At trial, although Smith could not identify appellant, she did identify the towel and hat seized from his car as those worn by the robber. Cubeta, who had identified appellant in a photo lineup conducted immediately after the robbery, testified that he was “positive” that it was appellant who had robbed him.3 Cubeta also identified the towel, shirt, pants, and jacket seized during the search of appellant’s room and car as those worn by appellant during the robbery. The Commonwealth called two additional witnesses at trial who testified that they had seen appellant’s distinctive car at the crime scene immediately before and after the robbery.4
Because Cubeta conceded at trial that he was unable to identify appellant positively during the preliminary hearing, appellant argues that Cubeta’s “in-court” identification testimony should have been disregarded. According to appellant, the other evidence presented “is just as consistent with innocence as with guilt.” (Appellant’s brief at 25) We disagree.
It is essential to the fair administration of justice that appellate tribunals not sit as second fact-finders. Rather, on appeal the evidence must be viewed in the light most favorable to the verdict winner with all reasonable inferences flowing therefrom. Commonwealth v. Rose, 463 Pa. 264, 244 A.2d 824 (1975). When so viewed, the evidence presented below is undoubtedly sufficient to support appellant’s convictions. The record shows that Cubeta had an adequate opportunity to observe appellant in good lighting conditions and that he identified his photograph immediately *438after the robbery. Accordingly, the trial court did not abuse its discretion in admitting Cubeta’s identification testimony, see Commonwealth v. Connolly, 478 Pa. 117, 385 A.2d 1342 (1978); Commonwealth v. Kahley, 467 Pa. 272, 356 A.2d 745 (1976), cert. denied 429 U.S. 1044, 97 S.Ct. 746, 50 L.Ed.2d 757 (1977), and we will not engage in re-evaluating his credibility. Commonwealth v. Stickle, 484 Pa. 89, 398 A.2d 957 (1978); Commonwealth v. Yost, 478 Pa. 327, 386 A.2d 956 (1978) (plurality).
Appellant also contends that Cubeta’s in-court identification was the result of a suggestive confrontation at his preliminary hearing. Since this claim was not advanced either at the suppression hearing or at trial, it has been waived. Commonwealth v. Clair, 458 Pa. 418, 326 A.2d 272 (1974); Compare Commonwealth v. Sexton, 485 Pa. 17, 400 A.2d 1289 (1979).
Appellant next claims error because the trial judge refused to recuse himself. When this matter initially was called to trial on January 13, 1976, the Commonwealth sought a continuance because it could not locate Barbara Lee, a critical witness. The prosecutor told the trial court that Lee would testify that on October 7,1975, she drove appellant to and from the crime scene and that appellant told her that he had robbed Smith and Cubeta. The continuance was granted and trial began on March 30, 1976, but Lee remained unavailable. Appellant contends that the trial judge should have recused himself because his knowledge of Lee’s possible testimony prejudiced him against appellant. We do not agree.
It is well settled that the burden to show bias and prejudice is always on the party seeking recusal of a judge. A judge’s refusal to recuse himself will not be reversed absent a clear abuse of discretion. Crawford’s Estate, 307 Pa. 102, 160 A. 585 (1931). When the question of prejudice has arisen in the context of non-jury criminal trials, our courts have considered whether a judicial fact-finder is more capable of disregarding prejudicial evidence than a lay *439jury.5 We have generally adhered to the prevailing view that judicial fact-finders are capable of disregarding most prejudicial evidence.6
*440In the instant case, the trial judge expressly noted in his opinion that he gave no effect to the prejudicial evidence:
For whatever it may be worth, the writer of this opinion, who was the trial judge, can unequivocally state that no consideration was given to any evidence not presented to the Court at the trial, the statements of the Assistant District Attorney made on January 13,1976, and the defense counsel’s reference to the same on March 30, 1976 were totally disregarded. The difference between the expectations of counsel as to what their witnesses will say and the realities of their testimony are a phenomenon well known to Court and counsel. (Opinion of the trial court at 10-11)
Since appellant failed to sustain his burden of demonstrating prejudice, we conclude that the trial judge properly refused to recuse himself.
Appellant next contends that evidence discovered subsequent to his conviction requires the grant of a new trial. After an evidentiary hearing, the trial court correctly rejected this claim. State Trooper Gary Carter testified at trial that during his search of appellant’s car he found sixty-two dollars in denominations of one and five dollar bills in a green money bag and fifty-eight dollars and ninety-one cents in a tackle box.7 Although appellant testified at trial, he presented no contradictory evidence.
After trial, appellant allegedly noticed for the first time that the seized bills and coins listed on the property receipt given to him by Carter after the search8 totalled one hun*441dred and twenty dollars and ninety-one cents rather than sixty-two dollars, and that no mention was made of a tackle box. At the evidentiary hearing, appellant introduced the stipulated testimony of another trooper that a property report prepared by the state police disclosed that one hundred and twenty dollars and ninety-one cents had been found in the green money bag.9 Appellant testified at the hearing (1) that Carter found nothing during his search of the car (2) that appellant then removed the green bag containing one hundred twenty dollars and ninety-one cents from the car and gave it to Carter, and (3) that Carter removed fifty-eight dollars and ninety-one cents from the bag, leaving sixty-two dollars therein.10 Carter also testified at the hearing and reaffirmed his trial testimony. He clarified the notations in the property receipt and report by explaining that after discovering the fifty-eight dollars and ninety-one cents in the tackle box, he had placed it in the green bag in which he previously had found the sixty-two dollars.
We have often stated that after discovered evidence will warrant the granting of a new trial only if the evidence (1) was unavailable at the time of trial despite counsel’s due diligence to obtain it, (2) is not merely cumulative or offered only to impeach credibility, and (3) is likely to compel a different result. Commonwealth v. Lee, 478 Pa. 70, 385 A.2d 1317 (1978); Commonwealth v. Miller, 465 Pa. 458, 350 A.2d 855 (1976); Commonwealth v. Tervalon, 463 Pa. 581, 345 A.2d 671 (1975). While assuming arguendo that ground two had been satisfied, the lower court rejected appellant’s claim on the first and third of these grounds. We conclude that the court’s decision may be affirmed on either ground. First, the evidence was available to appellant before trial. A copy of the property receipt was served on him upon completion of the search. The receipt was again introduced *442at appellant’s pre-trial suppression hearing and was appended to the suppression court’s opinion. Thus, any ambiguity in the Commonwealth’s evidence could have been raised at trial.
In addition, the trial court concluded that Carter’s explanation of the amount of money he found in the green bag was credible and disbelieved appellant’s belated efforts to supplement his trial testimony. Thus, the court found that the evidence was not likely to compel a different result at trial. In so ruling, the court acted well within its discretion. Commonwealth v. Tervalon, supra.
Finally, appellant contends that the warrant issued in the early morning hours of October 8, 1975 for the search of his car and hotel room was not based on probable cause.11 The warrant included the following affidavit of probable cause, sworn to by the state trooper investigating the Smith and Cubeta robberies:
On the date 7 Oct 75 at approximately 5:00 p.m. investigation of an Armed Robbery at Smith’s Grocery Store RD # 2 Fayetteville, Pa. along the S. side of US 30 Greene Twp. Franklin Co. Penna. Armed Robbery committed by a negro male, 5'9"-5'll", 175 lbs. Lt. colored medium black hair wearing Brown Jacket Dk. Trousers and dark hat with Pink towel with white checks over face. Information obtained from Charles William BUMBAUGH RD # 1 Chambersburg, Pa. had seen an orange colored car Florida Reg. and mag wheels with female operator drop off a colored male approximate description as above at the intersection of Brownsville Rd and Black Gap Rd approximately 500 ft. from the scene of the Armed Robbery at approximately 4:45 p. m. Vehicle then proceeded to a church parking lot just south of the Intersection and parked. Vehicle was also seen by Lawrence W. CUFF 510 Brumbaugh Ave. Chambersburg, Pa. which he described as a 1972 Orange colored Pont. Grand Prix with Florida *443Reg. parked in a driveway along Brownsville Rd. at approximately 5:00 p. m. occupied by a colored Female and colored male. Information received from J. Chester DIL-LER RD # 1 Waynesboro Pa. that said vehicle occupied by Barbara Lee & Glenn COUNCIL was traveling N. on PA 997 in the direction of Scene at approximately 4:00 p. m. Information received from Chief Harold GINGRICH Washington Twp. Police Dept, that he conducted an investigation on the night before involving said Pont. Sdn. and Glenn COUNCIL at the area of Diller’s orchard along PA 997 Washington Twp. Franklin Co. Penna. Check with Bureau of Motor Vehicle Florida revealed that Glenn COUNCIL to be a colored male 5'9", 170 lbs. Black hair Brown eyes Date of Birth 4/2/42 and is listed owner of vehicle mentioned. Information obtained from Waynesboro Police Dept, that above subjects are presently staying at Anthony Wayne Hotel Room 425 120 W. Main St. Waynesboro, Pa. and said vehicle parked outside Hotel. Request night time search be made due to Subjects being found at the Anthony Wayne Hotel at 0200 hrs. this date.
Probable cause to issue a search warrant has been defined as those facts reasonably necessary to show (1) that the items sought are connected with criminal activity, and (2) that the items will be found in the place to be searched. Note 28 U.Chi.L.Rev. 664, 687 (1961); See Brinegar v. United States, 338 U.S. 160, 69 S.Ct. 1302, 93 L.Ed. 1879 (1949); United States v. Old Dominion Warehouse, 10 F.2d 736 (2d Cir. 1926) (Hand, J.); Amsterdam, Segal, and Miller, Trial Manual for the Defense of Criminal Cases, § 241 (ALI 1971). See also Pennsylvania v. Mimms, 434 U.S. 106, 109, 98 S.Ct. 330, 332, 54 L.Ed.2d 331 (1977) (“The touchstone of our analysis under the Fourth Amendment is always ‘the reasonableness in all the circumstances of the particular governmental invasion of a citizen’s personal security.’ ”)
In determining whether a search warrant is based upon probable cause, “we would do well to heed the sound admo*444nition of United States v. Ventresca, 380 U.S. 102, 108, 85 S.Ct. 741, 745, 13 L.Ed.2d 684 (1965)”:12
[T]he Fourth Amendment’s commands, like all constitutional requirements, are practical and not abstract. If the teachings of the Court’s cases are to be followed and the constitutional policy served, affidavits for search warrants, such as the one involved here, must be tested and interpreted by magistrates and courts in a commonsense and realistic fashion. They are normally drafted by the nonlawyers in the midst and haste of a criminal investigation. Technical requirements of elaborate specificity once exacted under common law pleadings have no proper place in this area. A grudging or negative attitude by reviewing courts toward warrants will tend to discourage police officers from submitting their evidence to a judicial officer before acting.
When so viewed, giving due deference to the conclusions of the issuing magistrate,13 the warrant provided ample basis for the police reasonably to believe that the various articles of clothing and proceeds of the Smith and Cubeta robberies would be found in appellant’s car and hotel room. Accordingly, we conclude that the evidence seized during the search was properly admitted at trial.
Order affirmed.
ROBERTS, J., filed a dissenting opinion.. The evidentiary basis for the warrant is discussed below.
. The police also seized pants, a shirt, and an additional fifty-eight dollars and ninety one cents.
. Appellant does not now challenge the propriety of the lineup identification.
. Appellant owned an orange 1972 Grand Prix Pontiac with red and white Florida license plates.
. Commonwealth v. Green, 464 Pa. 557, 561, 347 A.2d 682, 683 (1975):
In effect appellant is arguing that the mere exposure to prejudicial evidence is enough to nullify a judge’s verdict in a case. We cannot subscribe to such a view, for it is the essence of the judicial function to hear or view proferred evidence, whether testimonial or in exhibit form, and to decide whether or not it should be admitted into evidence, or if admitted initially or provisionally, should later be excluded or disregarded. For us to accept appellant’s contention would be, in effect, to find disqualification of a judge to be a judge;
