¶1Appellant contends that his sentence should be vacated and the case remanded because the trial court did not state its reasons for the sentence imposed on the record at the time of sentencing. We agree and, accordingly, vacate judgment of sentence and remand for resentencing at a hearing of record.
¶2On October 6,1976, a jury convicted appellant of aggravated assault and recklessly endangering another. On April 21, 1977, appellant pleaded guilty to charges of kidnapping, burglary, criminal conspiracy, disposition of ransom, and unauthorized use of an automobile. On June 13, 1977, the trial court sentenced appellant on these convictions to a term of imprisonment of 9 to 23 years. The court did not state on the record at time of sentencing the reasons for the sentence. Appellant filed a timely petition to vacate sentence and, on December 30, 1977, the court reduced the sentence to a term of imprisonment of 8 to 20 years. Appellant then filed this appeal. The trial court, in its opinion filed pursuant to Pa.R.App.P. 1925, stated reasons for the sentence imposed.
¶3Appellant argues that the trial court failed to comply with the requirement of Commonwealth v. Riggins, 474 Pa. 115, 377 A.2d 140 (1977), that the trial court state its reasons for the sentence imposed on the record at the time of *84sentencing.
¶4One compelling reason for Riggins' requirement is that without a statement of reasons at the time of sentencing, the defendant lacks an opportunity at that time to bring to the court’s attention any erroneous facts or conclusions upon which it may have relied and is unable thereafter to file a petition for resentencing challenging the court’s reasons for imposing sentence. See Commonwealth v. Riggins, supra, *85474 Pa. at 129 n.16, 377 A.2d at 147 n.16. Rigginsalso emphasized that, after sentencing, a defendant should first seek relief in the trial court, which is best able to recognize the merit of sentencing claims. Id.,474 Pa. at 136, 377 A.2d at 151. Accord, Pa.R.Crim.P. 1410 (effective July 1, 1978); see Commonwealth v. Walls, 481 Pa. 1, 391 A.2d 1064 (1978) (sentencing claim not preserved for appellate review unless first presented to trial court). When the trial court does not state its reasons for the sentence imposed on the record at the time of sentencing, it denies the defendant opportunity for swift relief, ignores the direction of Rigginsthat the trial court consider thé merits of sentencing claims in the first instance, and forces appellate courts to make initial determinations of issues which they should consider only on review, if at all.
¶5Here, the trial court did not, on the record at the time of sentencing, inform appellant of the reasons for the sentence imposed. Thus, appellant was then unable to assess the court’s conclusions or file a petition for reconsideration of sentence specifically challenging the court’s reasons. The court modified the sentence, but did not then give its reasons for doing so. Only after appellant filed this appeal did the court, in its opinion, reveal the reasons for the sentence imposed. Regardless of whether appellant’s sentence is excessive, see note 2 supra, this Court would have to make an initial determination of a claim the trial court should have considered first. Had the trial court had the opportunity to consider appellant’s specific contentions, it might have corrected any alleged error and the matter would never have reached the appellate stage. It was to avoid just this situation, and the possible injustice it holds, that Rigginsrequired a statement of reasons on the record, at the time of sentencing.
¶6Therefore, we vacate sentence and remand for a sentencing proceeding of record. See, e. g., Commonwealth v. Jefferson, 484 Pa. 115, 398 A.2d 971 (1979) (applying Riggins to cases on direct appeal at the time it was decided); Commonwealth v. Fields, 478 Pa. 479, 387 A.2d 83 (1978); Commonwealth v. Riggins, supra.
¶7 Appellant’s claim is preserved for review. As required, he first sought relief in the trial court. See Commonwealth v. Walls, 481 Pa. 1, 391 A.2d 1064 (1978). After the trial court modified sentence, appellant had no obligation to file another petition for reconsideration. The trial court had already indicated the full extent of the relief it was prepared to grant. The Commonwealth does not argue that appellant should have filed another petition in the trial court. Appellant also contends that his sentence was manifestly harsh and excessive. We do not consider this claim.
