Gattis, who returned to the Astros' starting lineup in left field Tuesday at San Diego, hit a two-run homer in three at-bats. Gattis' home run in the first inning off Padres' starter Tyson Ross was his second this season. Astros manager A.J. Hinch previously said he wanted to start Gattis in left field at least once during the team's three-game Interleague series at San Diego, so he'll likely be in the lineup again Wednesday.
