Hall of Fame:


Lefty Grove starred for the great Orioles teams of the 1920s, delaying his appearance in the major leagues until he was 25. But he made up for the lost time, winning 300 games and posting an amazing .681 winning percentage. He was the ace of Connie Mack's 1929-1931 American League champion Philadelphia A's, and won 105 games for the Boston Red Sox after he was sold and had arm trouble. An intense competitor who destroyed his share of clubhouses after tough losses, Grove was considered the greatest left-handed pitcher of his time, and one of the best in history.

Quotes About

"All things considered, Grove is the best lefthander that ever walked on a pitcher's slab. He surpasses everybody I have ever seen. He has more speed than any other lefthander in the game." — Connie Mack, 1931 "Waddell was a remarkable pitcher. We all know that. But he wasn't dependable. He didn't take care of himself. Grove isn't that way. Lefty's always in condition. He's as dependable as the tides... He's faster than Waddell, too." — Connie Mack, 1931

Best Season

Grove followed up his amazing 1930 season (28-5, 18 relief appearances, and nine saves) with an even better year. He helped the A's to their third straight pennant, no small feat with Gehrig and Ruth's Yankees in the same league. Grove went 31-4, with a league-best 2.06 ERA. The league ERA was 4.51. He also led in K's, WHIP, complete games, and shutouts. He won 16 games in a row. Once again he proved valuable out of the pen, saving five games. He was honored as the league's MVP.

First Tilt by the Lake

On July 31, 1932, the Indians moved into their new ballpark, Municipal Stadium. Mel Harder and Grove tangled in a pitcher's duel won by Lefty, 1-0, on Mickey Cochrane's RBI single. More than 80,000 were in attendance.

Streak Stopper

The New York Yankees posted a somewhat unbelievable feat of playing 308 straight games without being shut out, beginning August 2, 1931. Two years and one day later, Lefty Grove stopped the streak, blanking Ruth, Gehrig, Dickey and the gang, 7-0, on August 4, 1933.

Sunday's Best

On August 22, 1926, after three straight rainouts, Connie Mack decided that the time for Sunday baseball in Philadelphia had come. Armed with a court injunction preventing police from interfering, the A's played the White Sox in a light rain that kept the crowd down to 10,000. Lefty Grove started and won the first Sunday game in Philadelphia, 3-2. A court later ruled that Sunday baseball was still illegal, and it wasn't until 1934 that the law was abolished in Philadelphia.
