Trumbo has been dealing with intermittent pain in his right ankle for about a month, Scioscia said. He added that it's rare for a player not to feel some sort of discomfort in the final week of a 162-game regular season.
"He's been dealing with it off and on for a month," Scioscia said. "It's nothing he couldn't manage."
Trumbo has gone deep twice against Sunday's starter Rich Harden this season in six at-bats. He homered off him once in Angel Stadium and once in Oakland on the recently concluded road trip.
Vernon Wells also has homered twice against Harden in 22 career at-bats. He's hitting .318 against the hard-throwing right-hander.
Maicer Izturis, who is 3-for-22 (.136) in his career against Harden, was the odd man out in the lineup, taking his clutch bat to the bench for late-inning opportunities.
