SAN DIEGO (AP) – Chris Young pitched one-hit ball for seven innings, Khalil Greene homered twice off Tim Wakefield and Josh Bard hit a contested homer to lead the San Diego Padres to a 6-1 win over the Boston Red Sox on Saturday night.

The Padres snapped a three-game losing streak and leapfrogged the Los Angeles Dodgers back into first place in the tight NL West. Young and relievers Heath Bell and Justin Hampson combined on a four-hitter, and Boston’s three-game winning streak ended.

Third base umpire Brian Knight, a fill-in, had a rough night. Two of his calls were overturned, including one that gave Bard an opposite-field, two-run homer against his old team and led to Boston manager Terry Francona being ejected.

With the Padres leading 3-0 with one out in the sixth and Mike Cameron aboard on a double, Bard drove the first pitch from Wakefield off the foul pole on the side of the Western Metal Supply Co. brick warehouse in the left-field corner.

Bard hopped out of the batter’s box, then threw up his hands in disbelief when Knight ruled it a foul ball. Padres manager Bud Black came out to argue, the umps huddled and Bard was waved around the bases, giving the Padres a 5-0 lead. It was Bard’s third homer of the year.

Francona came out and spoke with crew chief Dana DeMuth, then vented on Knight and got tossed. It was Francona’s second ejection this season.

Greene followed with a shot into the left-field seats to chase Wakefield. It was Greene’s 11th of the season and his sixth career two-homer game.

In the fifth, Boston left fielder Manny Ramirez dove for Kevin Kouzmanoff’s sinking liner and Knight ruled it a catch. Black argued, the umps huddled and sent Kouzmanoff to first. Replays showed Ramirez trapped the ball. Kouzmanoff eventually scored on Marcus Giles’ double into the left-field corner.

Bard, traded from Boston to San Diego early in the 2006 season, finished with three RBIs.

Young (7-3) pitched brilliantly in his first start since being ejected after exchanging punches with Chicago’s Derrek Lee a week earlier at Wrigley Field. The 6-foot-10 right-hander dropped his home ERA to 0.94, the best in the majors, and struck out 11 to miss his career high by one. He dropped his overall ERA to 2.08.

The only hit Young allowed was J.D. Drew’s single in the fifth, and he walked only two.

Young has appealed his five-game suspension for his part in the melee in Chicago, and the Padres pushed back this start by one day to lessen the sting if his punishment is upheld.

He’s due to start Friday at the Los Angeles Dodgers and July 4 at home against Florida. He could then take the suspension, serving four games before the All-Star break and one game after.

It didn’t take the Padres long to figure out Wakefield’s knuckleball.

Mike Cameron, who came in 2-for-16 lifetime against Wakefield, led off the second by beating out a bunt for a single, stole second and scored when Bard doubled over Ramirez’s head.

Greene homered leading off the fifth, driving an 0-2 pitch into the seats in left-center. After Kouzmanoff was awarded first on the overturned call, he was sacrificed by Young and scored on Giles’ double into the left-field corner to make it 3-0.

Wakefield (7-8) allowed six runs and eight hits in 5 1-3 innings, struck out four and walked none.

The series concludes Sunday with a marquee matchup between Josh Beckett (10-1) and Jake Peavy (9-1).

Notes: Greene reached double digits in homers for the fourth straight season. … Boston C Doug Mirabelli was booed during his second-inning at-bat, then cheered when he struck out on three pitches. Mirabelli was with the Padres for the start of the 2006 season, but made it clear he wished he was back in Boston. When the Padres dealt him back to the Red Sox for Bard and reliever Cla Meredith, Mirabelli reportedly told Dave Roberts, “I guess I’m getting called back to the big leagues.”
