Choo has been hitting off a tee and is hoping to progress to soft toss on Tuesday. If that goes well, he will travel with the Rangers to Oakland this weekend and start taking regular batting practice.
The next step would be facing pitching in game situations. The Minor League season is over, but the Rangers have 85 players in instructional league in Surprise, Ariz.
At some point Choo will join that group.
"I'll be the top prospect," Choo joked.
Choo has time. The Rangers won't begin postseason play until Oct. 6, the scheduled date for Game 1 of the American League Division Series.
The Rangers have a set outfield of Ian Desmond and Carlos Gomez, plus the platoon of Nomar Mazara and Delino DeShields, but they miss Choo's presence in the leadoff spot.
The Rangers have four players with at least 100 leadoff at-bats, and Choo has the highest on-base percentage, at .362, followed by DeShields at .319, Jurickson Profar at .316 and Rougned Odor at .259.
The Rangers are currently using Gomez in the leadoff spot against right-handers and DeShields against left-handers.
"[Choo] has been the most consistent leadoff option we would have," manager Jeff Banister said. "If we can get him back, that would be great. We have seen what he can do in the leadoff spot."
