Black favors moving in Petco's fences

SAN DIEGO -- Count Padres manager Bud Black among those in favor of moving the Petco Park fences in.

The Padres are considering modifying the dimensions of the pitcher's park to make it more hitter friendly. Opening in 2004, Petco Park ranked last among the 30 Major League ballparks in runs scored in four of its first six seasons, according to park factors. The ballpark ranked 28th among the 30 teams in 2011.

"It's a great discussion," Black said. "We've talked about it before. It's a good idea to talk about moving them in.

"I don't want to get into all the details of how far in from right-center and all that, but I'm in favor of moving the fences in."

Parrino gets into starting lineup at shortstop

SAN DIEGO -- Infielder Andy Parrino found himself in the Padres' lineup for Wednesday afternoon's game against the Nationals at Petco Park. He started at shortstop and hit second.

The night before, Parrino came off the bench and delivered a single that led to a run in the Padres' 3-1 loss to Washington.

Whether he's making an occasional start or pinch-hitting and playing defense late in a game, Parrino said he has to be prepared. His preparation has paid off -- entering Wednesday's game, he was hitting .320 (8-for-25) with two doubles and a home run.

"Every once in a while, it's nice to get in there and get some ABs, but no matter what, I'm ready to play every day," said Parrino, who made his Major League debut last season with the Padres. "Especially being in the National League, you always have to be ready for double-switches and everything late in the game. I'm ready to go every day."

Parrino entered Tuesday's game in the seventh inning and hit a single off Tyler Clippard. Center fielder Jayson Werth mishandled the ball, allowing Cameron Maybin to score on the error.

"When you're coming in late, the biggest thing is to stay aggressive, try to get a good pitch to hit, and put it in play hard somewhere," Parrino said.

Parrino won one of the Padres' final roster spots coming out of Spring Training. In the Minors, Parrino played various positions and was accustomed to sometimes having a bench role.

Wednesday marked his fifth game at shortstop. He has also played five games at second base and one game at third base this season.

"The biggest thing that helped me down there was playing a lot of different positions," Parrino said about his time in the Minors. "That just got me more comfortable being able to play different positions in the infield, and even some of the outfield."

Worth noting

• Starting pitcher Dustin Moseley underwent right shoulder surgery Wednesday morning to repair damage to his rotator cuff and labrum. Moseley went on the disabled list April 8.

"There was nothing unexpected when they went in and had a look," manager Bud Black said. "They felt it was successful."

The surgery was performed at Scripps Clinic Carmel Valley. Head team physicians Dr. Heinz Hoenecke, Dr. Jan Fronek and Dr. Daniel Keefe were involved in the surgery.

• Left fielder/first baseman Jesus Guzman was out of the Padres' lineup Wednesday for a second consecutive game after he had two teeth on the right side of his mouth removed on Monday. Guzman said he was doing OK. Black said Guzman was "more available" to play Wednesday than he was Tuesday, and Guzman did get a pinch-hit single in the 7-2 loss.

Guzman said he might be back in the starting lineup Thursday.

• Second baseman Orlando Hudson has raised his average from .097 on April 14 to .200 after Wednesday's game, in which he homered. He also has an eight-game hitting streak.

"His lower half is working better. We're seeing a little more bat speed and better swings, even on foul balls," Black said before the game. "Even [hitting coach Phil Plantier] commented that his cage work was good."
