(My Sportsbook) - Chris Young will attempt to remain undefeated on the season when his San Diego Padres kick off a three-game set with the Colorado Rockies tonight at Coors Field.

Young was held to just 18 starts last season due to injury and began this campaign with back-to-back wins, allowing just two earned runs in his first 13 innings.

The right-hander was then pounded for seven runs in just 3 2/3 innings on April 17 versus Philadelphia, but got a no-decision in his team's eventual 8-7 win. Young responded with a seven innings of shutout ball versus San Francisco on Wednesday, but again got a no-decision after his team needed an extra inning to post a 1-0 victory.

Young is 5-1 with a 3.28 earned run average in 11 career starts versus Colorado, going 3-1 with a 4.20 ERA in six starts at Coors Field.

San Diego needs Young to stay strong with ace Jake Peavy struggling. Peavy fell to 2-3 on Sunday after allowing five runs in five innings of an 8-3 loss to Pittsburgh.

Adrian Gonzalez hit a two-run homer for the Padres, who tumbled to their fifth loss in six games. Gonzalez has four homers in his last seven games and his seven long balls on the season are tied for first in the NL with Albert Pujols of St. Louis.

Edgar Gonzalez hit a solo shot in the loss.

San Diego will take its swings tonight against Jason Hammel, who makes his first start of the year for the Rockies in place of the injured Franklin Morales.

Hammel has made three relief outings this year, giving up two runs and seven hits in 6 2/3 total innings of work. However, 28 of his 76 career appearances have been starts, all with Tampa Bay. The 26-year-old righty is 4-13 with a 6.41 ERA as a starter in his three-plus year career.

Hammel has faced the Padres once in his career, a 6 2/3-inning relief sting in which he allowed three runs.

Colorado snapped a three-game skid on Sunday with a 10-4 victory. It marked the second time this year that the Rockies have plated a season-high 10 runs and they are sixth in the NL with 86 runs scored. However, Colorado is next- to-last in the league in team ERA (5.55).

Ryan Spilborghs and Jeff Baker each knocked in three runs on Sunday, with Spilborghs going deep. Clint Barmes finished 2-for-4 with a two-run homer and scored twice for the Rockies, who won for just second time in nine games.

Jason Marquis (3-1) got the win by allowing six hits and three runs with five strikeouts and four walks over 7 1/3 innings -- the longest for a Colorado starter in 2009.

Garrett Atkins is a career .280 hitter (7-for-25) versus Young with three homers and six RBI.

These two clubs split 18 meetings last season, with the Rockies winning five of nine at home.
