Baseball Almanac Top Quote

"He (Dave Koslo) had control and he could win at the Polo Grounds because he could keep the ball low and away. He wasn't overpowering, didn't have what you could call a good curve, but wouldn't walk anybody." - Stan Musial in Stan Musial: The Man's Own Story as Told to Bob Broeg (Stan Musial, Doubleday Publishing, 1964)

Did you know that when Dave Koslo won the ERA Championship in 1949, finishing the year with a National League leading 2.50 ERA, he had a losing (11-14) record? Did you know he wasn't the first ERA Title recipient with a losing record, joining Ted Breitenstein (19-20 in 1893, 3.18 ERA), Rube Waddell (8-13 in 1900, 2.37 ERA) and Dolf Luque (16-18 in 1924, 2.63 ERA)?

On April 18, 1947 , Jackie Robinson hit his first Major League home run. Dave Koslo was on the mound, the score was tied 1-1, it was during the top of the third inning, the bases were empty, and the shot cleared the wall in left field. Jackie took Koslo deep four additional times in his Hall of Fame career, second most versus the seventy-six pitchers he homered off, behind Hall of Famer Robin Roberts (9 HRA).

Allie Reynolds pitched a no-hitter on July 12, 1951 , and September 28, 1951 . When the New York Yankees selected him to start Game 1 of the 1951 World Series , it was not the least bit surprising. The New York Times (John S. Roadosta, "Dave Koslo Is Dead at 55", 12/03/1975) wrote, "Koslo was a surprise starter in the first game of the 1951 World Series against the Yankees . He was unflappable and deliberate against such Yankee hitters as Mickey Mantle , Hank Bauer and Joe DiMaggio and against his opponent, Allie Reynolds , who had pitched two no-hit games. Koslo held the Yankees to seven hits and the Giants won 5-1. 'That Koslo surprised me,' said Casey Stengel , the Yankee Manager. 'I didn't think he could pitch such a game. Besides bothering us with his control, he was ahead of the hitters all afternoon.' No big thing, Koslo said, 'Ever since I was a kid,' Koslo added, 'I thought of pitching a World Series. Now that I have, I've found it to be just another ball game. I've pitched in tougher games during the regular season.'"
