Jim Mason spent the 1973 season as the backup shortstop to starter Toby Harrah.
Jim showed up 74 times at shortstop, 19 times at second, and once at third base. He played 562 innings at short and saw 337 chances. He committed 18 errors on the season which left him with a .947 fielding percentage, well below the league average .964 percentage. Interestingly, Jim put in more time in the field than some of the regular players.
At the plate Mason barely topped the Mendoza Line with a .206 batting average. He managed a .273 on base percentage in his 266 plate appearances. Jim definitely did not hit for power, he managed only three home runs all season.
1973 cemented Jim Mason as stuck behind Toby Harrah at short. That wasn't to say that he didn't have an upside. At least the Yankees thought he did. In December of 1973 they purchased Jim's contract from Texas.
