CHICAGO — Bobby Jenks was activated from the 15-day disabled list Friday and declared himself ready to return to the closer's role for the Chicago White Sox.

Jenks went on the DL on July 9 with bursitis near his left (non-pitching) shoulder. He hasn't pitched in the majors since June 29. He did throw in two minor league rehab games during the All-Star break.

"Hopefully, he is healthy. He threw a couple of games and he's fine. Hopefully, he don't have any setbacks and we are going to use him the way we've been using him the last couple of years," manager Ozzie Guillen said.

The 6-foot-3, 275-pound Jenks is 2-0 with a 1.95 ERA and 18 saves in 21 chances this season.

"No pain," Jenks said, adding that his rehab outings accomplished what he needed. "My biggest concern was making sure my control was there.,

To make on the 25-man roster for Jenks, the White Sox optioned right-handed pitcher D.J. Carassco to Triple-A Charlotte on Thursday.

UPTON PUT ON DL: The Arizona Diamondbacks placed right fielder Justin Upton on the 15-day disabled list because of a strained oblique muscle Friday night, making room for newly acquired first baseman Tony Clark. The Diamondbacks sent minor league pitcher Evan Scribner to the San Diego Padres for Clark, who played three seasons for Arizona before signing with the Padres as a free agent.

ORTIZ HITS 2ND HOMER IN REHAB: Boston Red Sox slugger David Ortiz hit his second homer in as many games of his minor league rehabilitation assignment with the Triple-A Pawtucket Red Sox on Friday night. Ortiz, recovering from a wrist injury, came to bat in the fifth inning with Pawtucket leading Toledo 3-1 and runners on second and third and two outs. Anastacio Martinez tried to slip a 1-1 fastball by Ortiz on the outside corner but the AL All-Star designated hitter belted a three-run homer to left to give Pawtucket a 6-1 lead.

SEXSON IN YANKEES' LINEUP: Richie Sexson finalized his contract with the New York Yankees on Friday and was immediately plugged into the starting lineup against Oakland left-hander Greg Smith. The Yankees signed the big first baseman who was released by Seattle last week. Sexson slumped badly against right-handed pitching with the Mariners, but hit .344 with five home runs in 71 at-bats against lefties this year. He came through right away for New York, hitting a two-out RBI single in his first at-bat.

FREEL TO HAVE SURGERY: Reds outfielder Ryan Freel will have surgery on Wednesday to repair a torn tendon that attaches to the bottom of his right hamstring. Freel went on the disabled list on June 4 after he injured the hamstring. It's unclear how long he will need to recover from the surgery.

OAKLAND ACTIVATES CROSBY: The Oakland Athletics activated shortstop Bobby Crosby from the disabled list Friday and moved left-hander Dallas Braden into their rotation. Braden, who had been pitching in relief, will replace Joe Blanton in the rotation. Blanton was traded to the Philadelphia Phillies on Thursday for three minor leaguers.

ROCKIES OPTION REDMAN: The Colorado Rockies designated left-hander Mark Redman for assignment Friday and recalled right-hander Juan Morillo from Triple-A Colorado Springs. Redman appeared in 10 games with the Rockies this year, nine of them as a starter, and was 2-5 with a 7.54 ERA. He began the season in the Rockies' rotation before being sent to Triple-A Colorado Springs on May 11.

CUBS PLACE LIEBER ON DL: The Chicago Cubs placed Jon Lieber on the 15-day disabled list because of a right foot strain on Friday and recalled infielder Micah Hoffpauir from Triple-A Iowa. The 38-year-old Lieber is 2-3 with a 3.43 ERA this season.

PADRES RECALL HENSLEY: The San Diego Padres recalled right-hander Clay Hensley from Triple-A Portland on Friday, filling a roster spot a day after trading Tony Clark to the Diamondbacks. It's the second stint in the majors this season for Hensley, who did not pitch in his first one earlier this month.

NATIONALS PUT PENA ON DL: Nationals outfielder Wily Mo Pena went on the 15-day disabled list Friday because of an injured left shoulder that will require surgery.

GUILLEN OUT WITH BACK SPASMS: Kansas City Royals cleanup hitter Jose Guillen was out of the lineup Friday night against the Chicago White Sox because of back spasms. Manager Trey Hillman said Guillen took batting practice in a cage three straight days during the All-Star break, but he began to have back spasms Thursday night. Billy Butler was the DH and cleanup hitter Friday night.

CARDINALS RECALL FLORES: The Cardinals activated reliever Randy Flores from the 15-day disabled list on Friday, opting for an eight-man bullpen during a stretch of 18 consecutive games. "We want to have that extra pitcher rather than the extra player," manager Tony La Russa said. "I'd rather have one less move to make on the position player side." Right-hander Kelvin Jimenez also was recalled from Triple-A Memphis, while rookie right-hander Chris Perez and outfielder Joe Mather were optioned to Memphis.
