Travis Jackson is one of a long series of famous shortstops on the New York Giants. Though still young and with years of athletic service left, he was handicapped by a knee injury which nearly ended his career in 1932. Last year, 1934, he found a new lease on life when moved to third base. Knee and shoulder injuries are the most disastrous hurts in baseball, effecting speed of foot and throwing. Jackson is still one of the best hitting infielders in the game, a rarity, since a shortstop who can hit above .300 and field above .970 is rated doubly valuable in a day when managers will often carry a man who hits a bare .250 for the sake of his sharp fielding.
