SAN DIEGO -- No matter what happens, the San Diego Padres continue to hang onto the NL West lead.
The Padres lost shortstop Khalil Greene with a broken toe and dropped below .500 Sunday, becoming the first team to lead a division with a losing record this late in the season.
Rookie Robinson Tejeda pitched seven strong innings, Chase Utley and Pat Burrell had two-run singles in a seven-run fifth inning, and the Philadelphia Phillies beat the Padres 8-3 to complete a three-game sweep.
San Diego (58-59) remains three games ahead of the Arizona Diamondbacks.
"It doesn't matter what your record is if you win the division," Padres manager Bruce Bochy said. "We're not trying to win this thing playing sub-.500 ball. It's going to take over .500 ball to win this division, I firmly believe that.
"Unless we do that, we won't win."
The loss of Greene could have a major impact, especially since he was one of the few Padres who have hit consistently lately. Bochy said Greene is expected to miss 2-3 weeks.
"That one hurts," right fielder Brian Giles said. "Guys are going to have to step up with the way he's been playing defense for us and getting big hits on offense."
San Diego has scored 11 runs while losing four of five.
The Phillies, 20-11 since July 9, moved within a half-game of Houston in the NL wild-card race and finished their West Coast road trip with a 5-1 record.
The first nine batters reached base on six singles, two errors, and a walk in the fifth, the Phillies' biggest inning of the season.
"Until that point, (Chan Ho) Park was throwing pretty well and was in control," said David Bell, who started the inning with a single. "But we got a couple of hits that really changed the game."
Greene said he broke his left big toe when he jammed it into the ground while he dove for Todd Pratt's single to left field in the third inning.
"It's frustrating, but it's a part of the game," Greene said. "It's disappointing, but there's not much you can do about it."
The last team to lead a division with a losing record in August was the Texas Rangers, who topped the AL West at 52-62 on Aug. 11, 1994, the day before a labor strike ended the season.
"Maybe we caught them at the right time," Philadelphia manager Charlie Manuel said. "They're going to be all right. It's just a matter of time before they get hot."
Tejeda (3-2) pitched longer than six innings for the first time in 11 starts. The right-hander allowed one run and three hits with six strikeouts and three walks.
"I was still comfortable after seven," Tejeda said. "That was great to be able to go seven. When I pitched before we weren't scoring so many runs, but today we kept the ball in play."
Park (1-1) pitched four-plus innings, allowing six runs and five hits.
Bell led off the fifth with a single and Pratt walked. Tejeda laid down a sacrifice bunt that was fielded by catcher Miguel Olivo, whose throw to third sailed into left field for an error and allowed Bell to score for a 2-1 lead.
Kenny Lofton followed with a bloop RBI single that knocked Park from the game. Clay Hensley came in and gave up a two-run single to Utley before a throwing error by Eric Young loaded the bases. Burrell made it 7-1 with his single and Ryan Howard singled in the seventh run of the inning.
The Phillies took a 1-0 lead in the fourth on Howard's RBI single. Giles led off the bottom half with his 12th homer, which barely made it out as it hit on top of the right-field scoreboard and fell short of reaching the seats.
Tejeda allowed two hits in six shutout innings in his other start against the Padres, a 2-0 win on July 23 at Philadelphia.
The Padres scored twice in the eighth on a bases-loaded groundout by Ryan Klesko and a wild pitch by Rheal Cormier.
Greene also suffered a broken right ring finger on April 17 and missed three weeks. ... Tejeda had gone six innings in four other starts. ... The Phillies have beaten San Diego 10 consecutive times, last losing on May 22, 2004, at Philadelphia.
