Ken Hentzelman, Pitcher, Philadelphia Phillies - One of the fiercest of the Philtin' Phillies last year (1949) was lefty Heintzelman. He was powerful help in making the once weak-and-meek, a bunch of red-hot competitors with his inspired pitching. He won 17, lost 10; led Phil hurlers in innings pitched (250), EGRA 3.02 - and was feared around the league.
