ground-ball pitcher (1957)

“‘Our records show that Lon Berberet (who was the batter) had hit six fly balls to left field against right-handed pitchers this season. Obviously we didn’t want him doing that in this situation. So, I called for [Al] Aber, who is a ground ball pitcher. That’s just what we needed.” Tigers manager Jack Tighe quoted in Joe Falls, “Nats’ Occasional Good Game Costly to Tigers,” Detroit Times, May 21, 1957, p12
