PHOENIX -- Michael Wuertz isn't looking to repeat last year's lengthy shoulder woes.

The A's righty thinks he has a good chance of avoiding them given the different treatment he's receiving this time around with the help of new trainer Nick Paparesta. In fact, the injured hurler said he could be back on a mound in three to four days and feels he can remain healthy the rest of the way.

Wuertz left the A's workout facilities early Monday with what he described as the typical shoulder soreness he experiences most springs. He tried to pitch through the discomfort last spring, which ultimately forced him to miss the first month of the season.

"We're taking a different course of action this year," Wuertz said. "We're acting on it early so that it doesn't become a problem later on."

The 32-year-old Wuertz, who lives in Arizona during the offseason, has been working with pitching coach Ron Romanick since January. He was already up to 45-pitch bullpen sessions, putting him far ahead of a normal schedule.

"I may have increased my workload a bit too much, too soon," he said. "That extra torque early on probably flared it up."

Nevertheless, the A's have plans to take it easy with Wuertz, Andrew Bailey and Craig Breslow this spring after the workload they received last year, so missing a few days isn't of concern at this point.

Cahill set to start Cactus League opener

PHOENIX -- Coming off an All-Star season that put him on the national map, A's righty Trevor Cahill will look to pick up right where he left off when he gets the first crack at game action this spring.

The 22-year-old Cahill is slated to start Sunday's Cactus League opener against the Cubs at Hohokam Stadium in Mesa, Ariz., at 1:05 p.m. MT. Bobby Cramer, Tyson Ross and Josh Outman -- all considered candidates for the fifth starter spot -- will follow Cahill in the afternoon contest.

Also slated to throw Sunday are relievers Brad Ziegler, Joey Devine and non-roster invitee Danny Farquhar.

The A's will hit the road once again Monday when they make the short trip to Tempe, Ariz., where the Angels will face scheduled Oakland starter Dallas Braden. Tuesday's home opener against Cincinnati will see lefties Brett Anderson and Gio Gonzalez on the mound.
