Pittsburgh's pitchers are feeding off each other's success these days.Karstens pitched six sharp innings, Freddy Sanchez homered and the surging Pirates beat the Florida Marlins 3-2 on Tuesday night.Karstens allowed one run and three hits for the Pirates, who lead the league in ERA and have won four of their last five games. Sanchez finished with three hits."A lot of people doubted us, but we all believe in ourselves and we all believe in each other," Karstens said of the staff that has a 3.00 ERA so far this season after finishing with an NL-worst 5.10 ERA last year. "That's all that matters right now. Enough can't be said for [new pitching coach Joe Kerrigan]; we're more prepared than any team in the league."Ohlendorf allowed two hits over seven innings as Pittsburgh beat Florida 8-0 on Monday for its third shutout in four games. The Pirates have four shutouts this season; the other 13 NL teams have combined for six.

Karstens, acquired from the New York Yankees in the Xavier Nady trade in July, didn't allow a run in his first two Pirates starts but had been 0-6 since."He kept the ball down and did a nice job," Pittsburgh manager John Russell said. "He got through six, which is pretty solid start for him at this point of the season."The Pirates scored in each of the first three innings to build a 3-1 lead. Adam LaRoche drove in Nyjer Morgan with a first-inning single, and Jason Jaramillo picked up his first major league RBI with a run-scoring double in the second.Sanchez led off the third with a drive to left-center off Anibal Sanchez (1-1).

The Marlins put two runners on later in the inning but John Grabow retired Hanley Ramirez on a popup and struck out Ross Gload to end the threat."It's funny, we were off to such a great start, everybody had been kind of used to slapping hands after the game," Florida second baseman Dan Uggla said. "These days are going to happen to you. You're going to run into some pretty good pitching day in and day out."Ramirez doubled in John Baker in the third for Florida. Sanchez allowed three runs and seven hits in seven innings."He got better as the game went on," Marlins manager Fredi Gonzalez said. "He got stronger as he threw. The velocity was there, the life on his fastball ... he pitched out of a couple jams early and only gave up one run each time."We just didn't hit. We had some opportunities to score some runs with the right people up, but we just didn't hit," he said. "That's the way it goes sometimes."
Marlins first baseman Jorge Cantu was scratched with a sore wrist. Gload took his place at first base and in the cleanup spot in the lineup. ...
