MIAMI(AP) Cody Ross and the Florida Marlins let their lead roll away.

Pinch-hitter Colby Rasmus hit a go-ahead single in the eighth inning after a costly error by Ross in center field, sending the St. Louis Cardinals over the Florida Marlins 6-5 Thursday.

Leo Nunez (2-3) took over in the eighth with Florida ahead 5-3. Rick Ankiel led off with a single, Albert Pujols walked on a full count and Ryan Ludwick singled. The ball got under Ross' glove and went to the wall, letting Ankiel and Pujols score the tying runs.

''I missed it, flat out,'' Ross said. ''Trying to block it and it just went right through my legs. The game is on the line right there and I got to come up with that play. There's no excuse.''

Rasmus batted for Trever Miller and singled to right.

''You just want to make contact,'' said Rasmus, who extended his career-high hit streak to 10 games. ''It's not like you're changing your thought process. You just want to have a good at-bat.''

Pujols hit his 19th home run and Ankiel added three hits for the Cardinals.

''Our production was pretty good again today,'' Ankiel said. ''I feel we're headed in the right direction and now we can head back home and hopefully keep it going.''

Ross Gload homered twice for the Marlins. He drove in three runs with the first multihomer game of his career.

''It didn't help us win the ballgame,'' Gload said. ''It wasn't enough.''

Miller (2-0) pitched a scoreless seventh. Ryan Franklin recorded his 14th save by going 1 2-3 innings.

Pujols reached into the first-base stands and caught Wes Helms ' foul popup with a runner on second for the final out. The Marlins finished 6-5 on their homestand.

''The homestand is a success because you have a winning record at home, but games like this, you want to win those games,'' Marlins manager Fredi Gonzalez said.

The Cardinals took a 1-0 lead in the first against Andrew Miller when Nick Stavinoha singled home Ankiel.

Gload put the Marlins ahead with a two-run homer in the second off Todd Wellemeyer .

Ronny Paulino had an RBI single in the Marlins fourth and Jeremy Hermida blooped an RBI single in the fifth for a 4-1 lead.

Miller was cruising along, having retiring 14 straight batters, until Ankiel singled in the sixth. Pujols followed with a two-run homer off the left-field foul pole.

''That wasn't a situation where I was going to nibble on (Pujols) at 3-1,'' Miller said. ''He's too good of a hitter, he's not going to chase a bad pitch. He's going to get his pitch and hit it. Unfortunately, he did.''

Gload responded in the bottom half, leading off with a home run to right. He went into the game with only one home run this season.

Wellemeyer allowed five runs and 11 hits in six innings. Miller gave up three runs and seven hits in 6 1-3 innings, striking out eight without a walk.

''We didn't make some adjustments against Miller, but we kept at it and came through,'' Cardinals manager Tony La Russa said. ''He was pretty tough on us, but then we found a way.''
