Kason Gabbard came up from Triple A and stuck around just long enough to give the Boston Red Sox a win.

Gabbard was called up from Pawtucket yesterday morning, waited through a storm that delayed his first pitch 2 1/2 hours, and went back down to the minors after striking out a career-high seven batters to lead Boston to a 6-3 victory over the Braves.

"It's not an easy thing for him," manager Terry Francona said. "He stayed ready. It's not an easy thing for anyone to do."

Making his 2007 debut, Gabbard (1-0) held Atlanta hitless through 3 2/3 innings and retired 12 of the first 13 batters he faced. He walked one and allowed six hits, leaving with a 6-0 lead after giving up back-to-back hits to start the sixth inning.

He was optioned back to Triple A after the game, and declined to comment on his start. Manny Delcarmen was called up so the Red Sox could have an extra reliever heading into this week's series with the Yankees, with Boston holding a double-digit lead over New York and Baltimore.

"If we need some help, we didn't want to get caught short," Francona said.

Brendan Donnelly relieved Gabbard and allowed both inherited runners to score. Atlanta reloaded the bases before Javier Lopez came in and retired Scott Thorman on a 3-6-1 doubleplay to end the inning.

Jason Varitek was 2-for-4 with three RBI for the Red Sox.

Alex Rodriguez hit his big league-leading 17th homer and Derek Jeter and Jorge Posada also connected for the Yankees.

Noteworthy

* The New York Daily News, citing anonymous sources, reported the Yankees might attempt to terminate Jason Giambi's contract if he is found to have used illegal substances after he signed a 7-year, $120 million contract in 2001.

The newspaper reported that sources said Giambi's contract contains language that would allow the team to void the deal if he uses illegal substances while with the club.

On Friday, the designated hitter told USA Today that he once used steroids. The commissioner's office is investigating the comment.

* Rookie outfielder Josh Hamilton was sent back to Cincinnati by the Reds to be checked out by team doctors after he was diagnosed with a stomach ailment on Saturday. He was taken to Lutheran Hospital at 5:45 a.m. on Saturday. The club said he had gastroenteritis, an inflammation or infection of the gastrointestinal tract.

* The White Sox activated Jim Thome from the 15-day disabled list and optioned outfielder Ryan Sweeney to Triple A Charlotte. Thome, on the DL since April 29 with a strained muscle in his rib cage, was called back from a rehab assignment with Charlotte. *
