STL@HOU: Cedeno singles home Krauss in the ninth

SAN DIEGO -- Newcomer Ronny Cedeno was in the Padres' starting lineup on Wednesday, playing shortstop and batting seventh, and the nine-year Major League veteran said he actually felt a little nervous about making his first start with his new team.

The finale vs. the Orioles marked Cedeno's first game in the Major Leagues since July 19. At the time, he was with the Astros before being designated for assignment on July 22.

The Padres signed Cedeno on Friday and he played two games for Class A Advanced Lake Elsinore -- where he was 1-for-8 with a double, a run scored and two walks -- before being added to the Major League roster on Tuesday.

In 51 games for the Astros this season, Cedeno hit .220 with six doubles and 12 runs scored.

"It was tough year for me," Cedeno said. "Now I'm excited to be here with great teammates, great coaches. I feel good and happy to be here."

Cedeno adds some needed stability to the Padres at shortstop after Everth Cabrera was suspended for 50 games on Monday for violating MLB's Joint Drug Prevention and Treatment Program. Cabrera will miss the remainder of the season.

"Ronny is a steady and dependable shortstop who knows how to play the game," said Padres manager Bud Black. "Hopefully he can play his game, both defensively and offensively."

Cedeno, who has played primarily at shortstop throughout his nine-year career, has spent time with the Mets, Pirates, Mariners and Cubs. He is a lifetime .245 hitter, with 38 homers, 230 RBIs and 253 runs.

Kennedy expects fewer nerves in second start

NYY@SD: Kennedy works into the sixth in strong start

SAN DIEGO -- Pitcher Ian Kennedy figures to be much calmer going into his second start with the Padres than he was during his debut with the team on Sunday.

"I was a little more excited than I wanted to be," Kennedy said. "If you watch me pitch, you'd see that I don't get too excited and try to stay on an even keel."

That was hard to do last week, as four days after being traded to the Padres from the D-backs, Kennedy stood atop the mound at Petco Park for his first start against the Yankees -- the team that drafted him in 2006 out of USC, and a team with several familiar faces on the roster.

"It was [the culmination] of the whole week. I didn't think it would be as stressful," Kennedy said. "But you want to get settled and find a place for your family to live, you're trying to meet your teammates and then you're pitching the next day against the team that drafted you."

Kennedy wasn't nearly as efficient as he wanted to be, needing 98 pitches to get through a start that covered 5 2/3 innings. He allowed two runs, had four walks and six strikeouts while earning the win.

The right-hander will make his second start with the Padres on Sunday in Cincinnati. His catcher, Nick Hundley, is expecting a cooler and calmer Kennedy.

"I think maybe as the game started, you have all that adrenaline, you're with a new team, and maybe you exert a lot of energy early," Hundley said. "It's not a normal start. It's really more like an Opening Day start, but with a new team.

"But he threw the ball great early, battled and gave us a chance to win."

Padres promote prospect Sampson to Triple-A

SAN DIEGO -- The Padres have promoted 22-year-old pitching prospect Keyvius Sampson from Double-A San Antonio to Triple-A Tucson.

Sampson, ranked as the 16th-best prospect in the system by MLB.com, was 10-4 with a 2.26 ERA over 19 games (18 starts) with San Antonio. He allowed 74 hits in 103 1/3 innings, with 110 strikeouts.

Sampson, a fourth-round Draft pick in 2009, began the season with Tucson but struggled there, going 0-1 with an 8.04 ERA in four starts.

Sampson was dominant with the Missions, though, especially after he began using his slider more often and with greater success.

The Padres also sent outfielder Donavan Tate, the No. 3 overall pick in the 2009 Draft, to short-season Eugene of the Northwest League.

Tate has been working out at the team's temporary Spring Training facility in Arizona since June after missing Spring Training. Tate has battled injuries and substance abuse since he was signed and joined the organization.

Short hops

• Catcher Yasmani Grandal had reconstructive surgery on his right knee on Tuesday in Florida. Grandal, who suffered a season-ending injury to the knee on a play at the plate in July, underwent an operation to repair his anterior cruciate ligament. He's expected to miss between nine and 12 months.
