Rockies-Padres Preview

Jul 18, 2015 - 7:00 AM The San Diego Padres have dominated the Colorado Rockies at home and giving the ball to Tyson Ross should see that continue.

Ross looks to match the longest winning streak of his career as the Padres try to beat the Rockies again Saturday night.

San Diego (42-49) is 6 1/2 games back of a wild-card spot, and a major reason is its 19-22 home record - one of the worst in the NL. The Padres, though, opened this 10-game homestand with a 4-2 win Friday.

"We've just to keep going, man," right fielder Matt Kemp said. "We've still got a long season; 70-some games left. We'll see where we end up at the end if we just continue to play good baseball."

The Padres have a 2.24 ERA while winning 14 of the past 17 home matchups with the Rockies (39-50), including five straight.

Ross (6-7, 3.34 ERA) now gets the chance to give them their first six-game run at home against Colorado since 1999. The right-hander is 3-0 with a 1.82 ERA and 29 strikeouts in 29 2-3 innings over his last five starts, and he also won a career-high four straight over a five-start span coming out of last year's All-Star break.

Ross struck out six and yielded three hits in 6 2-3 innings of a 2-1 win at Texas on Sunday.

"His stuff has been electric," interim manager Pat Murphy told MLB's official website. "His slider, at times, is as good as there is in the game."

Ross hasn't allowed a homer in 14 straight starts, one shy of the franchise record set by Dave Roberts in 1971. However, he's facing a Colorado team that is among baseball's leaders with 98 homers, and it's hit nine in the last five games at Petco.

Ross didn't get a decision in his most recent home matchup with the Rockies, tossing seven scoreless innings of a 2-1 win on Sept. 7, 2013.

He's lost all three meetings since with a 3.78 ERA and a homer in each, but they were all at hitter-friendly Coors Field.

He's served up one to Charlie Blackmon, who is 4 for 11 against him. Blackmon had a solo shot among his two hits Friday, giving him a .444 average (20 for 45) in his last 10 games.

The Rockies have dropped 13 of their past 17 games on the road.

Starter Chad Bettis (5-4, 4.91) has lost two of his last three road starts with a 5.94 ERA.

The right-hander matched his career high with five walks and allowed three runs in six innings of Sunday's 11-3 home win over Atlanta. That was an improvement after he was hammered for career worsts of 10 runs and four homers in 2 1-3 innings of a 10-2 defeat to the Los Angeles Angels on July 7.

Bettis has no record while striking out seven in 6 2-3 scoreless innings over four games against the Padres, but his only start came in a road loss on Sept. 8, 2013.

He's allowed Justin Upton to homer for his only hit in three at-bats in their matchups. Upton is 8 of 15 with two homers, two doubles and eight RBIs in four home meetings this season after connecting for a solo blast Friday.

Kemp also had a solo shot in the opener and is 11 for 24 with three homers and six RBIs over the last six games.
