Optimistic Phillies among teams to watch Wilson throw

ST. LOUIS -- With a strong performance this week in St. Louis and Detroit, the Phillies could be buyers before the July 31 Trade Deadline.

If they perform poorly, it seems likely they will sell.

The Phillies still believe they have a chance to make the postseason, which is why they will watch free-agent relief pitcher Brian Wilson throw Thursday in Los Angeles. Wilson is 15 months removed from Tommy John surgery. He threw Monday for the Giants, but Thursday's session is expected to include numerous teams looking for bullpen help.

The Phillies certainly are one of them. Their bullpen entered Tuesday's series opener against the Cardinals at Busch Stadium with a 4.36 ERA, which is the third-worst mark in baseball.

Phillies place reliever Savery on 15-day DL

ST. LOUIS -- The Phillies on Tuesday placed another relief pitcher on the disabled list.

Left-hander Joe Savery landed on the DL with stiffness in his left elbow. The club recalled left-hander Raul Valdes to take his place.

Savery last pitched July 13, throwing a scoreless inning in a 13-inning victory over the White Sox. He is 2-0 with a 1.38 ERA in 10 appearances.

"He was having trouble with his elbow," Phillies manager Charlie Manuel said.

Valdes was 1-0 with a 7.65 ERA in 10 appearances earlier this season with the Phillies before being demoted to Triple-A Lehigh Valley. He pitched as a starter with the IronPigs, going 3-4 with a 3.11 ERA in 12 starts.

Braun's lofty stats vs. Phils suspect amid suspension

ST. LOUIS -- Brewers left fielder Ryan Braun has caused nightmares for plenty of pitching staffs in his big league career, but none in the National League like the Phillies.

His 1.120 OPS in 186 plate appearances against the Phillies is his best mark against any NL team. It also is the ninth-highest mark against the Phillies by any player in history. Of course, those numbers fall under serious suspicion once he accepted a suspension through the remainder of 2013 for violations of Major League Baseball's Joint Drug Prevention and Treatment Program.

"I'm for cleaning up the game," Phillies manager Charlie Manuel said. "I want everything about it good. Baseball is something that I love and respect. It's been tremendous to me. I want it played right. I like both teams to play right. I like to see good players. Basically, I just want the game clean."
