MIAMI — The tall left-hander had not allowed a hit through six innings — and Randy Johnson was already out of the game.

Facing the Big Unit, 6-foot-8 rookie Sean West flirted with a no-hitter in his fourth career start.

West did not allow a hit until the seventh inning, Brett Carroll backed him with his first career homer, and the Florida Marlins beat the San Francisco Giants, 4-0, last night.

West (1-1) allowed one baserunner — a leadoff walk to Andres Torres in the third — through the first six innings. Edgar Renteria then lined a single to left on West's first pitch of the seventh.

"The no-hitter was on my mind the whole time, but I tried not to think about it," West said. "As soon as you think about it, karma's gonna take care of that hit."

Johnson has thrown two no-hitters, including a perfect game.

"It's a lot of pressure. You try not to think about it but it's there. But he has to be happy about the way he pitched," Johnson said.

West gave up two hits, one walk and struck out six in eight innings.

"I try to throw a no-hitter every start," West said. "If a hit comes up, I try to throw a one-hitter. If two hits come up, I try to throw a two-hitter, and so on."

Johnson (5-5), pitching on short rest, four days after he earned career victory No. 300 at Washington, allowed three runs, seven hits, three walks and struck out five in five innings.

PADRES 6, DIAMONDBACKS 3:

Kevin Kouzmanoff tied his career-high with four RBIs and Jake Peavy bounced back from the shortest start of his career to lead host San Diego over Arizona. Peavy (6-6) went seven innings, allowing two earned runs on seven hits. He struck out eight and walked two. Last Tuesday night, he left after just one inning of a 10-5 loss to Philadelphia due to the flu.

BRAVES 7, PIRATES 6:

David Ross grounded an infield single to deep short that scored Jeff Francoeur in the 15th inning for host Atlanta. Ross hit the grounder to shortstop Jack Wilson, whose throw to the third-base side of home plate pulled catcher Jason Jaramillo's foot off the plate as Francoeur slid in safely.

ROCKIES 5, CARDINALS 2:

Jason Marquis took the NL lead with his eighth win and Troy Tulowitzki homered for the first time in nearly a month, helping Colorado complete its first sweep in St. Louis. Marquis (8-4) allowed two runs in 6 2/3 innings.

WHITE SOX, TIGERS SPLIT:

Jose Contreras (1-5) allowed one hit in eight innings, getting his first win in nearly a year as host Chicago beat Detroit, 6-1, to earn a split in their day-night doubleheader.

ATHLETICS 4, TWINS 3:

Jack Cust hit a go-ahead solo home run, Jack Hannahan tied the game with a three-run double and host Oakland extended its best winning streak in three years to seven games. Oakland's Aaron Cunningham sustained a concussion after being hit in the head by a pitch.

YANKEES 5, RAYS 3:

Andy Pettitte pitched six innings and Johnny Damon hit a tiebreaking home run in the sixth inning for host New York. Mark Teixeira, Nick Swisher and Derek Jeter also homered for the Yankees. Pettitte (6-2) allowed three runs and five hits.

BLUE JAYS 6, RANGERS 3:
