OPINION OF THE COURT

Appellant was convicted on February 14, 1980 of the second degree murder^[1] of his girlfriend which occurred on February 8, 1972. In this direct appeal, the Appellant asserts three errors; first, the admission by the trial court of evidence of his prior criminal conduct; second, the trial court’s refusal to give a missing witness instruction; and, last, the ineffectiveness of his trial counsel.

Before reaching the merits of these contentions, however, we must address the Appellee’s argument that Appellant’s first two assertions of error had been waived. The record indicates that the issues of the Appellant’s prior criminal[*509] conduct and the court’s refusal to give a missing witness instruction were waived.

Appellant erroneously relies on Commonwealth v. Gravely, 486 Pa. 194,404 A.2d 1296 (1979) as supporting his argument that because the lower court addressed the merits of these issues in its opinion, the issues were preserved for appeal. Reliance on Gravely is misplaced for several reasons. First, Gravely represented a final, definitive statement as to whether certain issues would be preserved for appellate review despite failure to comply with Rule of Criminal Procedure 1123(a). The essence of the rule announced in Gravely was that “only those issues included in post-verdict motions will be considered preserved for appellate review.” 486 Pa. at 198-99, 404 A.2d at 1298. This rule was made prospective only, however, and cases wherein motions were filed prior to September 4, 1979 (60 days after the Gravely decision) were given the benefit of the “substantial compliance” rule which had developed in several previous cases. Appellant’s motion here was filed February 20, 1980.

Second, and more important, the question addressed in Gravely was the reverse of the question presented here. In Gravely, we considered whether issues not stated in post-trial motions, but nevertheless briefed and considered by the court below, were preserved for appellate review. In this case, the issues were stated in the post-trial motion, but were not briefed or argued. (The court below ruled that these issues had for this reason been waived, but addressed their merits in anticipation of the appealability of the waiver issue itself). In Commonwealth v. Williams, 476 Pa. 557, 383 A.2d 503 (1978), we held that where issues raised in post-trial motions were not briefed or argued, these issues are waived. The holding in Williams is controlling in this case. We write at length to make explicit what should have been abundantly clear after Williams and Gravely, that only issues which are raised in a post-trial motion in accordance with Rule 1123, and briefed or argued before the court hearing the motion, will be considered preserved for appellate review.

[*510] Appellant’s final contention is that his trial counsel was ineffective for failing to prepare and present a coherent defense and, further, due to our ruling today, for failing to preserve issues for appellate review. We find these claims devoid of merit.

In considering a claim of ineffectiveness of counsel for failing to preserve issues in the trial court for appellate review, this Court utilizes a two-step analysis. First, we must determine if the issues not preserved were of arguable merit, and if so, we must then determine whether the course chosen by counsel had some reasonable basis designed to effectuate his client’s interests. Commonwealth v. Burton, 491 Pa. 13, 417 A.2d 611 (1980). Counsel will not be deemed ineffective for failing to assert a baseless claim. Commonwealth v. Giknis, 491 Pa. 215, 420 A.2d 419 (1980).

The first claim waived by Appellant was that testimony of prior criminal conduct against the decedent should not have been admitted into evidence. The evidence showed that two days prior to the murder, the Appellant and decedent had argued and that decedent had fled the apartment with a cut lip and black eye (Tr. 90, 138-142). This testimony was clearly admissible to show malice, ill will or motive, Commonwealth v. Styles, 494 Pa. 524, 431 A.2d 978 (1981), and thus an allegation of error in this regard is devoid of merit.

Next, Appellant claimed that the lower court should have given a missing witness instruction when the Commonwealth failed to call an eyewitness to the murder. This claim is also without arguable merit since this witness was equally available to both parties.

In Commonwealth v. Jones, 455 Pa. 488, 495, 317 A.2d 233, 237 (1974), we articulated the “missing witness” inference rule as follows:

“ ‘[W]hen a potential witness is available to only one of the parties to a trial, and it appears this witness has special information material to the issue, and this person’s testimony would not be merely cumulative, then if such[*511] party does not produce the testimony of this witness, the jury may draw an inference it would have been unfavorable. See McCormick, Law of Evidence, 534 (1954). See also Bentivoglio v. Ralston, 447 Pa. 24, 288 A.2d 745 (1972), and Commonwealth v. Wright, 444 Pa. 536, 282 A.2d 323 (1971).’ Commonwealth v. Moore, 453 Pa. 302, 305, 309 A.2d 569, 570 (1973).” (Emphasis added)

On the basis of the record before us, to allow such an inference to be drawn would have been error since the record is devoid of any evidence that the witness was available only to the Commonwealth. In fact, the record clearly reveals that Appellant had an equal opportunity to question or call the witness.

Appellant’s final allegation of ineffectiveness of counsel must also be dismissed as lacking merit. Appellant contends that the defense presented by his counsel at trial lacked any strategy. He challenges counsel’s cross-examination of a Commonwealth witness and the alleged erroneous calling of two witnesses on Appellant’s behalf, ostensibly charging that these witnesses harmed rather than helped Appellant’s case. After a thorough review of the record, we disagree.

The well-established rule in this Commonwealth is that trial counsel will be deemed effective if the “particular course chosen by counsel has some reasonable basis designed to effectuate his clients’ interests. Commonwealth ex rel. Washington v. Maroney, 427 Pa. 599, 235 A.2d 349 (1967) (Emphasis in original)”, Commonwealth v. Upsher, 497 Pa. 621, 626, 444 A.2d 90, 92 (1982).

As to the cross-examination of the Commonwealth witness, counsel was attempting to impeach this witness and was successful to the extent that it resulted in the trial court’s instructions to the jury on inconsistent testimony and credibility (Tr. 328-329).

As to the calling of the first of two defense witnesses, the mere fact that the prosecutor’s cross-examination of that witness drew continuous objections by defense counsel is no reason to deem counsel ineffective for having called him.[*512] Moreover, in this instance, most of the objections of defense counsel were sustained, and thus could not be considered unfavorable to Appellant (Tr. 211-218).

Appellant’s complaint regarding the second witness being called because through him the murder weapon was introduced must also fail. As counsel stated at trial, he called this witness to negate an inference that Appellant fled the scene with the murder weapon, an action which we find had a reasonable basis and advanced his defense (Tr. 207).

Having reviewed Appellant’s contentions and finding none containing merit, we must affirm the Judgment of Sentence entered by the lower court.

Judgment of sentence affirmed.
