Jackson, entered as a defensive substitution in the sixth inning and doubled in the eighth for his first hit in 19 at-bats, avoiding tying a career-worst stretch. But Jackson was involved in a collision with Elvis Andrus at first base in the ninth inning and was visited by team trainers but remained in the game.
Manager Bob Melvin said before the game that it was time for Jackson to get some time off. He hadn't hit for much power -- Jackson cracked his second homer on Sunday to end a 49-game drought -- and he had only 22 RBIs in 69 games. Jackson has driven in at least 75 runs twice in his career.
"He's just trying a little too hard right now," Melvin said. "He's been up in some situations where there's been some runners on base, and in the past that's where he's really thrived is in RBI situations. To an extent, he's struggling a little bit and everybody goes through it during the course of a season."
Melvin, Jackson's manager for five seasons in Arizona from 2005-09, said it's more a mental thing than a physical one for the outfielder.
"He keeps himself in great shape," Melvin said. "He's ready to play every day, but sometimes it's just a little bit of a mental grind for a guy that's used to driving in some runs. Recently, he has been in a little bit of a funk offensively."
