Houston had been alone top the AL West for 49 consecutive days until losing Tuesday night. The Astros (77-70) finished a 2-8 trip and had just a one-game lead for the second AL wild card over Minnesota, which played later against the Los Angeles Angels.
Moreland's 21st homer was an opposite-field drive that just cleared the 14-foot-wall in left field in the third. Choo had a one-out single and Prince Fielder walked before Moreland made it 3-0 off rookie right-hander Lance McCullers (5-6).
Lewis (16-8) allowed two runs and seven hits. The right-hander, already with a career high for victories, struck out three and hit a batter.
The Astros play Oakland on Friday, the first of nine games in their final homestand of the regular season. They have the AL's best home record at 48-24.
Jed Lowrie had a two-out single for Houston in the fourth before an RBI double by Evan Gattis, a ball misplayed in left by Mike Napoli. Lewis then hit a batter before Luis Valbuena's RBI single closed the Astros to 3-2.
Houston had two runners on in the fifth when Colby Rasmus grounded into an inning-ending double play. Second baseman Rougned Odor went to his left to field the ball, and was falling away when he threw a strike to shortstop Elvis Andrus for the relay to first.

There was a moment of silence before the game to honor Hall of Fame broadcaster Milo Hamilton, who died earlier Thursday at age 88.
Hamilton spent 60 seasons broadcasting major league games, and had been with six other teams before going to Houston in 1985. He retired after the 2012 season and had since served as a guest radio commentator for select Astros home games.
