{¶ 1} We affirm the judgment of the court of appeals dismissing the petition of appellant, Lawrence E. Wilson, for a writ of mandamus to correct his sentence. The common pleas court was authorized under Crim.R. 36 to correct its clerical error in mistakenly characterizing the degree of the offense of which Wilson was convicted. See State ex rel. Cruzado v. Zaleski, 111 Ohio St.3d 353, 2006-Ohio-5795, 856 N.E.2d 263, ¶ 19. Moreover, Wilson had an adequate remedy by appeal to raise his claim of noncompliance with Crim.R. 32. Id. at ¶ 32. Finally, Wilson waived this claim on appeal by failing to raise it in his petition in the court of *342 appeals and by not seeking to amend his petition. See State ex rel. R.W. Sidley, Inc. v. Crawford, 100 Ohio St.3d 113, 2003-Ohio-5101, 796 N.E.2d 929, ¶ 32.

Judgment affirmed.
