MIAMI -- The drive down the left-field line took a surprising path, clanging off the foul pole for a homer by a batter who rarely hits them against a pitcher who rarely gives them up. Justin Steele Cubs Jersey . That narrow margin loomed large because of the way Jarred Cosart pitched against Adam Wainwright. Cosart went seven innings Tuesday to earn his first victory for the Miami Marlins, who beat Wainwright and the St. Louis Cardinals 3-0. Wainwright (14-7) missed a chance to become the first 15-game winner in the majors. He went seven innings and allowed three runs, with two coming on a fourth-inning home run by Donovan Solano -- only the sixth homer allowed by the Cardinals ace. "I thought for sure the ball was going foul," Solano said. He wasnt the only one. "That ball was 10 feet foul and it came back fair. It was just the craziest ball flight Ive ever seen," Wainwright said. "He thought it was foul, the umpire thought it was foul, I thought it was foul, everyone in the park thought it was foul. And then the ball started having this ball flight back to the pole, and it ended up hitting the pole. You cant do anything about that." It was stunner coming against Wainwright, who began the game with the best innings-to-homers ratio among all major league starters. The homer was Solanos first ever at Marlins Park in 133 games. His only other homer this year came against another All-Star, David Price. "You can book Donovan for every ace in the league from here on out," Marlins manager Mike Redmond said with a giggle. Cosart allowed three hits and one walk to win for the first time since July 7. The victory came in his second start for Miami after being acquired from Houston in a trade for prospects. "I think thats why I got traded -- they had confidence in my ability that I can help this team," Cosart said. "I have the utmost confidence in my own ability that I can come in here and help these guys win games and help make a playoff push." Hes 1-1 with the Marlins and 10-7 overall this year. Casey McGehee led off the Marlins fourth and hustled for a double when left fielder Matt Holliday was slow getting the ball back into the infield. Jarrod Saltalamacchia singled home the games first run, and Solano pulled an inside sinker for his homer. "I think I got so caught up trying to stuff it in there that I didnt juice it like I wanted to," Wainwright said. "That may be why he got to it. Youve got to tip your hat sometimes. It obviously looks ridiculously stupid that I gave up a two-run homer there, but the sad thing is it probably wouldnt have mattered because their guys pitched very good and we didnt score." TRAINERS ROOM Cosart, who missed his last turn because of a sore lower back, decided not to risk aggravating the injury at the plate. He took six strikes in two at-bats. FIRST SAVE With closer Steve Cishek given the night off, Mike Dunn came on with two on and two out in the ninth and earned his first save by retiring Matt Adams. The Marlins improved to 15-10 since the All-Star break. MVP? Marlins RF Giancarlo Stanton is aware of the buzz building that he deserves MVP consideration. "You understand what the possibilities are," he said, "but Im not typing MVP on Google every night." Stanton came into the game tied for the major league lead with 31 home runs, and he led the NL in RBIs, total bases and walks. He walked twice but also grounded into two double plays. UP NEXT Justin Masterson, who got only six outs in his most recent outing, starts for the Cardinals against Nathan Eovaldi in the final game of the series Wednesday. Masterson has an 11.25 ERA in two starts since joining the Cardinals, but manager Mike Matheny said he was encouraged by the way the right-hander threw in his most recent bullpen session.
