"If we get everybody back healthy, I'm going to try and rotate the guys more," Gibson said. "We've got a lot of decisions to make."
Second baseman Aaron Hill was activated Tuesday and placed right back in the starting lineup.
Willie Bloomquist, who had been getting the bulk of playing time at second recently, started at shortstop in place of left-handed-hitting Didi Gregorius, who got the got the day off with southpaw Gio Gonzalez on the mound for the Nationals.
Giving Bloomquist playing time at short against lefties would be one way of getting him into the lineup. In addition, Gibson probably will not play Hill for many games in a row, initially.
"It may go that way on some occasions, but he's fine, I don't have any problem with him on lefties," Gibson said of Gregorius. "He's very good what he does defensively. He's absorbed a lot for a young kid. We've asked him to do a lot and he's held up pretty well. You see him starting to swing the bat much better right now. He's starting to swing it back like he was."
Gregorius was hitting .194 against lefties and .341 against righties heading into play Tuesday.
Things will get even more crowded when third baseman Eric Chavez returns from the disabled list sometime in the next week.
