Bill Lefebvre from the Chronology

Mar 15, 1944 - In Maryland‚ the Senators start training with 5 knuckleballers likely to make the staff: Dutch Leonard‚ Roger Wolff‚ Mickey Haefner‚ John Niggeling‚ and Bill Lefebvre. Pity catcher Rick Ferrell‚ who will have to corral the flutterballs.

Jun 10, 1938 - Red Sox rookie pitcher Bill Lefebvre homers in his first ML at bat‚ on the first pitch and only plate appearance for the season‚ off Monty Stratton of the White Sox. But Lefebvre is hammered by Chicago in a 15-2 loss. He is the first AL player to homer in his only season at bat‚ and it will be his only ML homer‚ though he will finish with a .276 career average and lead the AL in pinch-hits in 1944. Stratton‚ the winning pitcher‚ gets his revenge in the 2nd inning when he connects for a grand slam off Lefebvre‚ who gives up 6 runs in 4 innings .
