He came up as a left fielder on the rookie-laden “Baby Braves” team in 2005, a team that featured rookies Brian McCann and Jeff Francouer. After missing the 2006 season recovering from Tommy John elbow surgery, Johnson switched to second base and hit .276 with 52 extra-base hits (16 homers) and 68 RBIs in 147 games in 2007, his first full season.
In 2008 he hit a career-high .287 with 57 extra-base hits, including 39 doubles, which also remains a career best.
His finest season came with Arizona in 2010, when Johnson had 67 extra-base hits, including a career-high 26 homers while hitting .284 with an .865 OPS in 154 games.
Last year he played some at first base, second base, third base and left field, and all but 44 of his plate appearances came against right-handers. He hit .220 with 18 extra-base hits (six homers) and a .653 OPS against righties, and .184 with four extra-base hits and a .690 OPS against lefties.
