Carter is batting .389 during his 11-game hitting streak and has raised his average above .200 (.205) for the first time this season.
"It's kind of what you visualize," Hinch said of Carter. "We've talked about this over and over throughout his season so far. Any given game, he can impact the game, and he did."
Carter homered to left field on a 3-2 pitch in the second, and hit a mammoth blast off the train high above left field on a 2-0 pitch in the fifth, both off Orioles starter Miguel Gonzalez. His 11 career multihomer games are tied for fifth in Astros history.
