Wallace was generally recognized as the AL's best shortstop from 1902 to 1911, when he served briefly as Browns player-manager. After moving from third to short, Wallace felt he'd found his place in the infield earning the nickname "Mr. Shortstop". He would also claim to have invented the continuous throwing motion, “As more speed afoot was constantly demanded for big league ball, I noticed the many infield bounders which the runner beat to first only by the thinnest fractions of a second.. I also noted that the old-time three-phase movement, fielding a ball, coming erect for a toss and throwing to first wouldn't do on certain hits with fast men...it was plain that the stop and toss had to be combined into a continuous movement.”
