BOSTON - The Boston Red Sox released catcher Javy Lopez on Friday, with manager Terry Francona saying it was a matter of not having "enough at-bats for him."
The Red Sox acquired the former Atlanta Brave on Aug. 4 from the Baltimore Orioles for a player to be named later to fill in for Jason Varitek, who missed August with a knee injury.
Varitek was activated on Sunday, and Lopez hasn't played since. To replace Lopez on the roster, Boston purchased the contract of catcher Ken Huckaby from Triple-A Pawtucket.
BRAVES: Manager Bobby Cox said third baseman Chipper Jones could be ready to return sometime next week, but that Jones' left side still ached when he attempted to swing.
At the earliest, Jones could be back by Tuesday or Wednesday, Cox said.
ASTROS: Roger Clemens will not make his scheduled start today against the Milwaukee Brewers because of a strained right groin.
"He's just not ready to go," manager Phil Garner said after hearing from Clemens, who is in Kentucky to watch his son, Koby, play for the Astros' Single-A Lexington Legends in the South Atlantic League Division Series.
Right-hander Jason Hirsh (2-3, 6.84 ERA) will take Clemens' place today.
YANKEES: Mike Mussina was moved back two days in the rotation after developing arm soreness from his previous start.
"His arm is a little achy," New York manager Joe Torre said. "Achy in the normal places, but he hadn't pitched in a couple of weeks so it's not unusual."
Mussina, 35, was scheduled to pitch Sunday against Baltimore. He will now face Tampa Bay on Tuesday. Jaret Wright will pitch in his place Sunday.
ATHLETICS: Oakland activated closer Huston Street from the 15-day disabled list Friday. Out since Aug. 19 with a strained right groin, Street had thrown 27 pitches in a simulated game Wednesday.
Oakland also recalled pitcher Jason Windsor from Triple-A Sacramento.
Right-hander Rich Harden, on the disabled list since June 5 with a strained ligament in his right elbow, threw 40 pitches during a bullpen session. He is scheduled to pitch in a simulated game Sunday.
REDS: Closer Eddie Guardado will be sidelined well into next season after having surgery Friday to repair a torn ligament and tendon in his left elbow.
The Reds acquired him from Seattle in a trade July 6. He pitched well at the outset, but his elbow started bothering him soon after he arrived. He was 10-for-12 in save chances when he went on the disabled list Aug. 20.
