SAN DIEGO -- Chris Young showcased his skills on Monday night. And it's a display the Padres hope to see for at least the next four years.

According to a source close to the team, the Padres will announce a four-year contract extension for Young today at a 10:30 a.m. press conference at Petco Park. The deal replaces Young's current contract and includes a team option for 2011, Young's first year of free agency. Terms of the deal were not available.

On Monday, Young went pitch-for-pitch with the San Francisco Giants' top young pitcher, Matt Cain, and then some, leading the Padres to a 1-0 win in front of 31,388.

Young allowed only four hits in seven shutout innings, while his agent, Lon Babby, and Padres general manager Kevin Towers watched from Towers' suite upstairs.

Cla Meredith pitched the eighth and Trevor Hoffman tossed a scoreless ninth for his 484th career save.

The win was the Padres' third straight by one run at Petco and gives the team a 59-22 mark in one-run home games since the facility opened in 2004.

Asked about the extension, Young said "I can't comment now."

Veteran pitcher David Wells had an opinion, however. The lefty said locking up Young, as well as right-handed pitcher Clay Hensley, is the right move.

"I think he's great," Wells said of Young. "He's a young guy who's competitive and throws strikes. They need to lock up everybody. Get Clay Hensley next and you've got a pretty good three.

"Anything less would be uncivilized."

Cain held the Padres hitless through the first six innings until Khalil Greene's leadoff double in the seventh. Russell Branyan followed with a walk before Jose Cruz Jr. perfectly placed a bunt down the third-base line to advance the runners.

Pinch-hitter Geoff Blum then followed with a long sacrifice fly into the right-field corner to score Greene.

"That's what I'm expected to do," Greene said. "Make things happen, get on base, get it started."

Young said this was how he hoped to have started at San Francisco last week. The 6-foot-10 right-hander yielded three earned runs in 5 2/ 3 innings in that effort. This outing, however, made a winner of Young (1-0), while Cain -- who allowed a run in seven one-hit innings -- was saddled with the tough loss.

"My job doesn't change based on the opponent," Young said. "I try not to get too wrapped up in it. But it's tough sometimes. I was upset with my first start. It's fun to pitch the way I'm capable."

Manager Bud Black had as much fun watching as Young kept the struggling Giants -- who have scored 14 runs in seven games -- off the board.

"Chris was outstanding," Black said. "That was two starting pitchers pitching toe-to-toe. Cain pitched great, but Chris matched him. He moved the ball in and out. He had good secondary pitches."

He also had painful pitches, including one that earned rookie Kevin Kouzmanoff a left elbow contusion after he was struck in the fourth inning. X-rays taken on Kouzmanoff's elbow were negative, and the team announced the rookie's status as day-to-day.

The game also marked the return of former Padres manager Bruce Bochy, who managed his first game from the visiting dugout in San Diego after 13 years as manager of the Padres.

Before the game, Bochy said he was excited for the return.

"I got to have some great memories, and those memories I will savor," Bochy said.
