FROM THE BASEBALL CHRONOLOGY » April 8, 1989: One-handed pitcher Jim Abbott makes his ML debut but lasts only 42/3 innings in California's 7–0 loss to Seattle. Abbott, who bypassed the minors completely after starring at the University of Michigan, will finish the season 12-12 with a 3.92 ERA, the most ML wins in a first pro season since the Browns Ernie Wingard won 13 in his 1st pro season, in 1925.
