Two players, both pitchers made their big league debut wearing the uniform of the Minnesota Twins on June 12.
Mike Kinnunen (P) – June 12, 1980 – Drafted by the Minnesota Twins in the 10th round of the 1979 amateur draft. Mike struck out his first big league batter but than a walk and a home run by Champ Summers became part of his debut. Kinnunen appeared in 21 games for Minnesota without getting a win, a loss or a save, as a matter of fact he didn’t get any wins, losses, or saves in his entire 48 game career. Mike held the MLB record for this stat until a few years ago when it was broken.
Gerry Arrigo (P) – June 12, 1961 – drafted from White Sox in 1960 first year draft. Only the fifth player in Twins history to make his big league debut wearing Minnesota across his chest. His debut was a start against the Red Sox at Fenway Park with only 2,984 fans in the stands. Arrigo pitched a scoreless first, then in the second inning he allowed a single to Frank Malzone, he hit Jim Pagliaroni with a pitch, Vic Wertz advanced the runners with a ground out to second. Don Buddin drew a walk and Red Sox pitcher Ike Delock singled to plate one run, than Chuck Shilling singled to score two more runs and Arrigo found himself with an unplanned early shower after just 1.1 innings.
