Notes: Encarnacion doesn't need DL

Cards outfielder suffering from right knee tendinitis

ST. LOUIS -- Juan Encarnacion is dealing with some knee tendinits, but nothing that should require him to be placed on the disabled list, Dr. George Paletta said on Monday. Paletta, the Cardinals' head team physician, consulted with the outfielder on Monday morning.

Due to a combination of the right knee issue and the arrival of Rick Ankiel, Encarnacion hasn't played since Wednesday against San Diego. He was originally in Sunday's starting lineup, but was a late scratch -- because of his knee soreness, the club said.

After highly productive months in June and July, Encarnacion has faded at the plate a bit in August. He's 7-for-27 (.259) this month with one extra-base hit for a .296 slugging percentage.

Encarnacion will receive medication to help ease the condition.

"Right now the recommendation is to keep him available and active," Paletta said.

Kennedy surgery Tuesday: Adam Kennedy will undergo surgery to repair the torn medial meniscus in his right knee on Tuesday, Paletta said. Performing the operation will be Dr. Lewis Yocum, the team doctor for the Los Angeles Angels of Anaheim.

Kennedy traveled to California on Sunday following the Cardinals' game against the Dodgers. He consulted with Yocum on Monday, and Yocum will operate on Tuesday. When Kennedy sustained a major injury to the same knee in 2004, Yocum performed the operation to repair his anterior cruciate ligament and medial collateral ligament.

Paletta said he expects Kennedy's recovery to take a full six weeks, a time frame that would take Kennedy to the final week of the regular season. Initial estimates on Kennedy's injury gave a recovery time of anywhere between two and six weeks, but ultimately the situation is complicated enough that the full time is expected to be needed.

Cards claim Barden: The Cardinals added some organizational depth on Monday when they claimed Minor League third baseman Brian Barden off waivers from the Arizona Diamondbacks organization. Barden has been optioned to Triple-A Memphis, where he will pick up some of the slack left when Brendan Ryan was called up to take Kennedy's roster spot in St. Louis.

Barden, 26, is having a rough year but has been a productive Triple-A player in the past. He batted .269 with a .355 on-base percentage and a .336 slugging percentage for Triple-A Tucson in 2007. In '06, Barden put up a .298/.361/.478 line for the Sidewinders, and in 2005 he hit .307/.363/.483 for Tucson. Barden is a lifetime .297/.353/.451 hitter in six Minor League seasons. He went 1-for-12 in a brief callup with Arizona this year.

He was a sixth-round Draft pick in 2002 out of Oregon State.
