Padres part ways with veteran Suppan

SAN DIEGO -- The Padres officially parted ways with veteran pitcher Jeff Suppan on Friday, as the team designated the 37-year-old right-hander for assignment.

Suppan was 2-3 with a 5.28 ERA in six starts for the Padres. He allowed 15 earned runs in his past three starts after allowing three in his first three starts with the team.

"Moving forward on the starting pitching side, we've decided to go in another direction in that spot," Padres manager Bud Black said.

Suppan, who signed a Minor League contract the week before Spring Training, joined the team May 2 when his contract was purchased from Triple-A Tucson.

He won his first two starts, defeating the Brewers on May 2 and then the Rockies six days later. In his last start with the team, he allowed six earned runs in five innings -- including two home runs -- during Monday's loss to the Cubs at Wrigley Field.

Suppan wasn't available for comment Friday.

"He handled it fine," Black said of his conversation with Suppan on Friday afternoon. "He's been around long enough to know this is a business and there are hard decisions along the way.

"He thanked us for the opportunity. He did everything that we asked."

Eric Stults will pitch on Sunday, the day Suppan would have thrown. Stults will pitch on regular rest since Thursday was an off-day for the team.

Maybin returns to lineup from wrist sprain

SAN DIEGO -- For the first time since Saturday, center fielder Cameron Maybin was back in the starting lineup.

Maybin left Saturday's game in New York with a sprained right wrist. The injury was the result of Maybin taking extra batting practice the previous week while the team was in St. Louis.

Maybin did appear on defense in Wednesday's loss to the Cubs.

"His wrist feels ready to go," Padres manager Bud Black said. "We're excited to have Cameron back. He's confident where he is."

Maybin hit second and started in center field against the D-backs, the first game of a three-game series at Petco Park.

Maybin had five hits in consecutive games against the Cardinals and Mets on May 23-24 but went hitless in his next six at-bats. He left that game against the Mets when the pain in his wrist became unbearable.

Short hops

• Infielder Andy Parrino has a sore right hand but is available to play.

"It's sore and it kind of crept up on him," manager Bud Black said. "It's been a little sore the last couple of weeks. It's a cumulative thing. We felt like we needed to slow him down."

Parrino has played third base, second base and shortstop this season.

• Right-hander Jason Marquis made his system debut Thursday, allowing one run in seven innings for Double-A San Antonio. Marquis, who signed a Minor League contract on Wednesday, struck out five and got 10 ground-ball outs. He was released by Twins earlier this month.

• Pitcher Joe Wieland, on the disabled list with a strained right elbow since May 7, is one week into his throwing program. He threw Friday, 10 times at 180 feet. He'll continue to build his endurance before getting on a mound for a bullpen session of some sorts, possibly late next week.
