ATLANTA — Cast in the unlikely role of last man standing among the Braves' four former 20-game winners, Mike Hampton prospered.

Hampton gave up two runs in six innings and Atlanta beat the San Francisco Giants 11-5 on Saturday night to end a five-game losing streak, including four straight at Turner Field.

Hampton gave the Atlanta rotation a lift on the day 300-game winner Tom Glavine confirmed he'll miss the rest of the season with an elbow injury. John Smoltz and Tim Hudson already have had season-ending surgeries.

Hampton (2-1) earned the second win of his comeback after missing the 2006 and 2007 seasons with elbow surgeries and having his 2008 debut pushed back almost four months by other injuries. He allowed seven hits with two walks and four strikeouts.

Jeff Francoeur, who hit eighth and began the night with a .227 batting average, had his first four-hit game of the season and drove in two runs. Greg Norton hit a two-run homer and Omar Infante also drove in two runs with two hits.

The Giants lost for the fifth time in six games. They have allowed 39 runs in the five losses.

San Francisco right hander Matt Palmer gave up seven hits and six runs in 2 1-3 innings in his major league debut. Palmer (0-1) started for Jonathan Sanchez, who was placed on the disabled list because of a strained left shoulder.

Palmer is the club-record 15th rookie to make his major league debut with the Giants this season. The 1954 Philadelphia Athletics are the last team to have 15 players appear in their first major league games before September, according to the Elias Sports Bureau.

Hampton earned his second win in his last three starts one day after Glavine returned to the disabled list with a torn flexor tendon in his left elbow.

Glavine said Saturday he plans to visit Dr. James Andrews in Alabama next week and said he would retire if elbow ligament replacement surgery is needed. Glavine expects to have surgery to repair the tendon. Smoltz has had shoulder surgery that could end his career, and Hudson had elbow ligament replacement surgery on Aug. 8.

Francoeur and Gregor Blanco had run-scoring hits off Palmer in the second before the Braves knocked the rookie out of the game by sending 10 batters to the plate in their four-run third. Infante had a RBI double, and Kelly Johnson, Francoeur and Hampton added run-scoring singles for a 6-0 lead.

Ivan Ochoa had two doubles and an RBI for the Giants.
