SD@ARI: Quentin's RBI single puts Padres on the board

SAN DIEGO -- Padres outfielder Carlos Quentin was scratched from the starting lineup for Monday night's series opener against the Reds at Petco Park with a sore left knee. Mark Kotsay got the start in left field.

He injured himself on a swing during Sunday's game against the D-backs, but manager Bud Black said Quentin should be available to pinch-hit.

"Q's been going at it pretty good over the last 2-3 months," Black said. "We don't need to push through this today."

The move left the Padres without their hottest hitter. Quentin has driven in 20 runs in July, second in the National League behind the Nationals' Jayson Werth (21). Each of Quentin's RBIs has come in his last 19 games.

Quentin has had injury issues this season, but hasn't had to miss any extended periods of time. He's played 81 games after playing in only 86 in 2012. Black has preserved Quentin's health by giving him regular off days.

"We have to maintain his health, and Carlos is a big part of that," Black said. "How he goes about it every day as far as getting in the weight room and doing everything he needs to do to keep his knees in a playable condition."

Black praises Ross' mechanics

SD@ARI: Ross allows no runs, strikes out seven

SAN DIEGO -- The thing that impressed Padres manager Bud Black the most about the career performance from starter Tyson Ross on Sunday was his delivery and how good he was mechanically.

"Tyson has that short stride, little funky in the back the way the ball comes out of his glove," Black said. "Big guy with a short stride."

The 6-foot-6 Ross repeated it all day long to stifle the D-backs through eight shutout innings. Even with the heat during the day in Phoenix, Ross wasn't fazed, and Black credited that to solid mechanics and an effective slider.

"The ball came out, and even from the side until the ball got in the hitting area I didn't know what it was going to be," Black said.

Ross was one of only four Padres starters since 1995 to allow three or fewer hits with seven or more strikeouts in eight innings.

"It's a great confidence builder," Black said. "Somebody told me once, if you do it one time, you can do it again."

Maybin closing in on rehab stint

SD@COL: Maybin slugs his first home run of the year

SAN DIEGO -- The Padres are discussing what's next for center fielder Cameron Maybin, who has been out since June 9 with damage to a ligament in his left knee.

Maybin is progressing well with his rehabilitation, and manager Bud Black liked what he saw on Monday.

"He's moving around like he's getting real close," Black said. "Might even be joining that [Triple-A] Tucson team before too long."

Maybin injured his knee after landing on it while attempting to catch a fly ball on June 9, just four games after he returned from 45 games away with a right wrist injury.

He hasn't had much of a 2013 season as the injuries have limited him to just 14 games and 51 at-bats. Maybin is hitting .157 with one home run, five RBIs and four stolen bases.

"I think the key is for him to get back on the field and play the rest of the season healthy," Black said. "How he plays, his legs are a big part of his game and speed, and the wrist is hopefully not a factor."

While the Padres saw good things from Maybin, there hasn't been much progress with outfielder Kyle Blanks and the tendinitis in his left heel.

Blanks became eligible to come off the 15-day disabled list on Saturday.

"It's sore. The doctors looked at it today and said it'll be a couple weeks," Black said.

Black wasn't even sure what exactly Blanks would be able to do in a couple weeks, but guessed that he is unlikely to be playing games in the Majors any time soon .
