Young "Pete" Coscarart, in his second season with the Brooklyn Dodgers, is being hailed by all Flatbush as the greatest second-baseman in the National League. Rival managers credit the Dodgers with having the best infield in the league, and Coscarart last year proved a main cog in it. Fielding is "Pete's" specialty, but he proved he can also come through with a timely hit by batting in 43 runs for the Dodgers in 115 games, and averaging .277, which is not at all bad for a freshman. Youngest of three ball-playing brothers, "Pete" started with Portland, where he was so valuable the fans gave him a farewell gift of $2500. He was purchased by the Dodgers in 1937, optioned to Nashville and recalled last year.
