CHICAGO -- The Padres already have three pitchers with 10 or more victories and could add another if Monday's pitcher, Kevin Correia, defeats the Cubs.

Clayton Richard (10-5), became the third Padres pitcher to win 10 games this season. The others are Jon Garland (11-8), and Mat Latos (12-5).

This is the first time since 2006 the Padres have had at least three pitchers reach double figures in victories. That season, Clay Hensley, Jake Peavy, Woody Williams and Chris Young won 10 or more games.

The 2006 team, of course, was the last Padres team to win the National League West.

The Padres have used only seven different starting pitchers this season. Young got one start in April before suffering a shoulder injury, and Tim Stauffer made a spot start in May in Houston.

"The thing that I've been most pleased with is the reliability of the five guys," Padres manager Bud Black said. "The durability and reliability speaks volumes. It's a good sign of stability."

Eckstein heading to Class A for rehab

CHICAGO -- At one point last week, Padres second baseman David Eckstein followed a question about his right calf strain with one query of his own.

"Do you know how many times I've gone on a rehab assignment?" Eckstein asked. "None."

That's not quite true, as Eckstein played five games with Dunedin, Fla., in 2008 when he was with the Blue Jays. But other than that, he hasn't played in a Minor League game since the 2000 season.

Eckstein is about to get another dose of the Minor Leagues on Wednesday when he will play the first of what is supposed to be three games with Class A Fort Wayne in a road series against West Michigan of the Midwest League.

And where does West Michigan play?

"Grand Rapids," Eckstein said, smiling. "I just looked it up."

Eckstein, who on Monday missed his 25th consecutive game with the injury, will play in three games, likely increasing the number of innings from five to seven and then nine in the final game on Friday.

Eckstein will then fly to Milwaukee to join the Padres, who begin a three-game series on Friday against the Brewers at Miller Park.

"For me, it's to test it in live competition. I don't care about the at-bats," Eckstein said before taking part in hitting and infield drills prior to the Padres game against the Cubs.

"It's just more making sure my body is healthy."

Young tosses fourth bullpen session

CHICAGO -- Pitcher Chris Young, on the disabled list since April with a strained right shoulder, threw his fourth bullpen session Monday at Wrigley Field.

Young threw around 50 pitches and threw his slider for the second time. He also threw from the stretch and the windup.

Next up will either be another bullpen session or possibly a simulated game on Thursday before the Padres face the Cubs at Wrigley Field.

"I was encouraged," said Padres manager Bud Black, who watched Young's session on Monday. "He's placing some checkmarks. "He's doing fine."

Black has said he's hopeful that Young will be able to pitch sometime in September.
