Gerald Sarantakis appeals from a judgment of a single justice of this court denying, without a hearing, his petition for relief under G. L. c. 211, § 3. We affirm the judgment.

Sarantakis was charged in the District Court with operating while under the influence of alcohol, fourth offense, and other offenses. On the day scheduled for trial, he pleaded guilty and was sentenced to a term in the house of correction. At the time she imposed the sentence, the judge mistakenly believed that Saran-takis’s most recent prior offense had occurred some nine years earlier. However, it soon came to light that Sarantakis apparently had two more recent out-of-State convictions. As a result, the same day as the sentencing hearing, the Commonwealth filed a motion, purportedly under Mass. R. Crim. R 29, 378 Mass. 899 (1979), asking the judge to exercise her discretion sua sponte to revise or revoke the sentence.1 At a hearing two days later, the judge stated she had not seen the Commonwealth’s motion. Acting on her own motion, the judge revoked *1020Sarantakis’s sentence, indicated that she would allow him to withdraw his guilty plea, placed the matter back on the trial list, recused herself, and directed that the matter be assigned to a different judge. Sarantakis’s G. L. c. 211, § 3, petition, seeking reinstatement of his original sentence,2 followed.

The case is before us on Sarantakis’s memorandum pursuant to SJ.C. Rule 2:21, as amended, 434 Mass. 1301 (2001), which requires him to “set forth the reasons why review of the trial court decision cannot adequately be obtained on appeal from any final adverse judgment in the trial court or by other available means.”3 In his memorandum, which primarily focuses on the merits of the judge’s decision to revoke his sentence, Sarantakis briefly asserts that he has no remedy in the ordinary appellate process. We disagree. If Sa-rantakis is resentenced to a longer term, he could raise the revocation issue on appeal from that decision. See, e.g., Commonwealth v. Derry, 26 Mass. App. Ct. 10 (1988) (sentence previously imposed on guilty plea revoked on judge’s motion; defendant resentenced to longer prison term). Sarantakis offers no reason why this approach would not provide an adequate opportunity to obtain appellate review of the decision revoking his original sentence. Saran-takis may have other options as well; for example, he could move to withdraw his plea if he is dissatisfied with the new sentence. In sum, he has not carried his burden under rule 2:21.

Judgment affirmed.
