Mark McGwire got the fireworks treatment usually reserved for the home team when he completed his collection of home run stadiums.
"I didn't even notice them," McGwire said of the mistaken blasts by the Cinergy Field crew assigned to celebrate Reds' exploits. "That's how much I was tuned in."
Fernando Tatis hit a pair of two-run homers as visiting St. Louis rallied to beat Cincinnati, 6-5.
McGwire's solo shot, his 33rd of the season and 490th of his career, came with one out in the ninth. After Ray Lankford singled, Tatis homered to put the Cardinals ahead.
Cinergy Field, formerly Riverfront Stadium, was the only current stadium in which McGwire had played a regular season game without hitting a home run.
BREWERS 5, PHILLIES 0: Hideo Nomo threw seven shutout innings and last-minute starter Lou Collier drove in three runs as Milwaukee beat visiting Philadelphia.
Nomo (9-2) gave up five hits and struck out five on another brutally humid day at County Stadium. He left the game before the eighth inning and missed his postgame news conference to get fluids into his body.
"He was tiring. When Mr. Nomo tells me he's had enough, Mr. Nomo's had enough," Brewers Manager Phil Garner said. "What else can you say? I'm kissing the ground he walks on."
Former Oriole Rocky Coppinger pitched two perfect innings in his second appearance for Milwaukee. He made his first major league plate appearance in the ninth, striking out.
CUBS 5, PIRATES 3: Cubs starter Terry Mulholland trailed right out of the box -- as he did in his last start, against Minnesota -- after surrendering three first-inning runs, but Chicago rallied at home to beat Pittsburgh.
"I just beared down after the first. Sometimes, you've got to be lucky in this game. I'm a ground-ball pitcher, and they were finding the holes early," Mulholland said.
ROCKIES 4-12, DODGERS 1-11: Bobby Jones and three relievers pitched a three-hitter and Colorado beat Los Angeles in the opener of the first day-night doubleheader at Dodger Stadium. The Rockies completed a sweep by outslugging the Dodgers in the nightcap; catcher Henry Blanco hit two of the Rockies' five home runs.
PADRES 8, GIANTS 7: Ben Davis hit a three-run homer and added an RBI double as visiting San Diego built an early six-run lead and held on to beat San Francisco.
Davis had three hits for the second consecutive game. He went 3 for 4 in the Padres' loss to the Giants Tuesday.
BRAVES 6, MARLINS 3: Atlanta took advantage of four Florida errors to snap a five-game losing streak by beating the host Marlins.
Chipper Jones, who leads the Braves with 23 homers, left the game after being hit on the wrist by a pitch. X-rays were negative, but Jones said he may miss a couple of games.
METS 7, EXPOS 4: Orel Hershiser reached the 200-win mark as New York hit a team-record six doubles in the second inning on its way to a win over the Expos in Montreal. Hershiser held the Expos to two runs and six hits in seven innings to win for the eighth time in his last 11 decisions. He also singled twice.
DIAMONDBACKS 2, ASTROS 1: Andy Benes hit a solo homer and pitched six strong innings to lead Arizona to victory over host Houston. "I've only hit six [home runs] in 10 years, so I don't have the right to pound my chest," Benes said. The Diamondbacks have won three straight.
