A right-handed pitcher, he worked in 28 games — all in relief — over parts of three seasons (1979–1980; 1982) for the Cleveland Indians of Major League Baseball.

After a strong 1979 season as a relief pitcher with the Triple-A Tacoma Tigers, Wihtol made his Cleveland and MLB debut that September when rosters expanded to 40 men.

Although treated roughly in his first two outings, Wihtol was unscored upon in his last three appearances to post a creditable 3.38 earned run average, with ten hits allowed in 102⁄3 innings pitched.

After spending all of 1981 and most of 1982 in Triple-A, Wihtol received a final trial with the Indians in September 1982, appearing in six more games without recording a decision or a save.

In 28 career Major League games, Wihtol allowed 54 hits and 24 bases on balls in 572⁄3 innings pitched, with 34 strikeouts.
