2011 Diamondbacks: The Diamondbacks traded for John McDonald in August, and McDonald has become the everyday starter in place of the injured Stephen Drew. McDonald has struggled at the plate since his arrival, hitting .169 in 59 at bats, down from his .250 average earlier in the season while playing for Toronto. McDonald is a career .238 hitter, but earns his paycheck with his defense. He has committed only a single error in the field this season, and has totaled 56 errors in 1886 career chances.
2001 Diamondbacks: In the first few years of his career, Tony Womack had been a menace on the basepaths, and led the league in stolen bases three times. By 2001 his speed numbers were down, and he only swiped 28 bases, but batted a respectable .266. Womack, never known to have an exceptional glove, had one of his worst defensive seasons in 2001, committing the fifth most errors of any National League shortstop in 2011. Womack committed 71 career errors at shortstop in 1,268 chances.
