Zimmermann’s unusual performance a first since Grove

Jordan Zimmermann allowed eight runs over seven innings but still managed to earn the win over the Minnesota Twins last night. It’s been just over two years since a pitcher got the win in a game in which he allowed at least eight runs; the Phillies’Cliff Lee surrendered eight runs over five innings on March 31, 2014 against the Rangers in a 14-10 win.

What was even more unusual was that Zimmermann struck out nine batters in Monday’s matchup. The last pitcher to earn the win while allowing at least eight runs and recording nine or more strikeouts was the Athletics’ Lefty Grove on May 30, 1927 against the Yankees (9 IP, 8 R, 11 SO in a 9-8 victory); those Yankees went on to finish the season 110-44 and swept the Pirates in the World Series. Babe Ruth went 2-for-5 with an RBI and Lou Gehrig was 1-for-4 with two runs batted in off Grove that day.

Zimmermann (6-2, 2.45 ERA) is the first pitcher to win at least six of his first eight starts for Detroit with an ERA under 3.00 since Doyle Alexander in 1987 (7-0, 1.61 ERA). The Tigers traded John Smoltz to acquire Alexander that season.

No adjustment period for Zimmermann

Jerry KoosmanJordan Zimmermann allowed one run in seven innings at Minnesota yesterday to improve to 5-0 on the season. Zimmermann, who signed with the Tigers this past offseason after seven seasons with the Nationals, is the fourth hurler ever to earn a victory in each of his first five games in the American League after having previously pitched in the National League. Bill McAfee was the winner in each of his first five appearances (two starts, three in relief) for the Washington Senators in 1932. Jerry Koosman won his first five games, all starts, for the Twins in 1979 after having a 3-15 record for the Mets the previous year. And Matt Palmer earned the victory in his first five appearances, all starts, for the Angels in 2009. Zimmermann’s 0.55 ERA is far lower than that of McAfee (2.49), Koosman (3.86), and Palmer (4.26) during their 5-0 starts.
