MIAMI — Omar Infante and Hanley Ramirez hit the Miami Marlins' first homers in their new ballpark, activating the much-discussed home-run sculpture and helping to beat the Houston Astros 5-4 in 11 innings Sunday.

Ramirez tied the game in the eighth against Wilton Lopez with a two-run homer that cleared the 418-foot sign in center field, then singled home the winning run with one out in the 11th.

Miami went 2-3 without manager Ozzie Guillen. The Marlins are off Monday and he returns Tuesday from a five-game suspension imposed after he angered Cuban Americans in South Florida by praising Fidel Castro.
