ST. LOUIS -- The lights went out, and then the air went out of Busch Stadium.After a 13-minute delay due to a power outage with one of the first-base light towers, Toronto's Jose Bautista launched a home run off Cardinals closer Fernando Salas as the Cards fell to the Blue Jays, 5-4, on Friday night. It looked for a brief moment as if right fielder Jon Jay would have a play on the ball at the wall, but the ball soared over his outstretched glove and into the Cardinals bullpen. Salas, who gave up the third home run in his last five appearances, has allowed a run in seven of his last 14 outings. The right-hander picked up his second loss of the year. Both defeats have come on home runs in tie games in the opponents' final at-bat. Despite the recent hiccups, Cardinals manager Tony La Russa said he was not concerned with Salas. "He just missed with a pitch, and the guy hit it," La Russa said. The loss spoiled a clutch hit from Matt Holliday, who tied the game in the sixth with a two-run home run that scored Jay. The long ball marked the second time the Cardinals had battled back to even from two runs down. Cardinals starter Jake Westbrook got off to a rough start, giving up two runs in the first inning to put the Cards in an early hole. The Blue Jays got to him again in the fifth, scoring twice and loading the bases before he was pulled for Mitchell Boggs. Westbrook gave up 10 hits in 4 1/3 innings, striking out three and throwing 100 pitches. The 10 hits were the most Westbrook has allowed as a Cardinal, and the outing was his shortest since May 11 at Chicago, when he lasted 2 1/3 innings. "I just wasn't very good from the start," Westbrook said. "I just kind of had to battle through the whole ballgame. Tonight I was just all over the place from the get-go, not controlling counts, making mistakes and putting our bullpen in a bind." Overshadowed in the late-inning defeat was a strong performance from the Cards' relievers, save for Salas' mistake to Bautista. Boggs kept the Cardinals in the game after entering in a tough spot with the bases full of Blue Jays and one out in the fifth. But he promptly struck out the first two batters he faced to end the threat. "If I didn't come in there and make some good pitches, it was going to be tough for us to come back," Boggs said. "I felt like if I could keep it where it was, we would have a chance to get back in it and possibly win the game." Lance Lynn pitched for the first time since being recalled from Triple-A Memphis on June 22, throwing three scoreless innings in relief, striking out two and giving up a lone hit. "Boggs was impressive, and Lynn was outstanding," La Russa said. The Cardinals bullpen kept the game within reach until the ninth, but Toronto's pitching was even better. Blue Jays starter Brandon Morrow went seven innings, allowing four runs (three earned) on five hits while striking out nine. Morrow found success once more against St. Louis. In his only other start against the Cards last season, he threw eight scoreless innings in Toronto. After Holliday's game-tying 380-foot shot, the Jays pitchers retired the final 12 Cards batters in order. As for Salas, the closer has responded this season after his poorest of outings, and the Cardinals remain confident in his ability to shake this one off. After all, he made one bad pitch to Bautista, who leads the Major Leagues with 23 homers. The slugger has gone deep seven times this season in the seventh inning or later. "He'll bounce back," Boggs said. "He's pitched in some tough situations and done really well. You've got to tip your hat to Bautista, because it didn't even look like a strike, and he went out there and got it." The Blue Jays snapped a four-game losing streak and broke out of an offensive funk. Toronto was coming off a three-game sweep at the hands of the Braves, against whom they managed just two runs on 13 hits. Bautista was struggling like most of his teammates, and was in a 3-for-18 skid before his game-winner. "I was looking for a good pitch, so I could hit it hard," Bautista said. "I've been working on my timing. I had gotten a little inconsistent for a few weeks, but the last couple days I feel like I'm more on time." Colby Rasmus belted his sixth home run of the year in the second to start the scoring for the Cards. Rasmus took the first offering he saw from Morrow deep to right field, sending it 390 feet into the Cardinals bullpen. The Cardinals fell to second place in the National League Central, one game behind the Brewers.
