Baseball notebook: Webb out one month

Brandon Webb’s pitching shoulder feels fine – until he pitches.

A nagging shoulder strain may sideline Arizona’s ace for another month.

Webb, who hasn’t pitched since opening day, will rest for three weeks after a setback on Friday. Then he hopes to ease back into the rotation with bullpen sessions and a possible rehabilitation start.

That means the Diamondbacks could be without the 2006 N.L. Cy Young Award winner until late May. Webb went on the 15-day disabled list April 13, retroactive to April 7.

“It’s frustrating because what I feel right now, I feel fine,” Webb said. “Just when I throw is when I get the pain. Hopefully, we’ll just give it a little more time to heal and we’ll be ready to go in a few more weeks.”

Pappy and Papi

The Red Sox now have “Big Pappy” to go along with Big Papi.

Arthur Giddon, who once shagged bats and balls for the Boston Braves, was the honorary batboy for the Red Sox on Saturday – the day before his 100th birthday.

Wearing a Red Sox jersey with No. 100 and “Big Pappy” written on the back, he sat with Boston slugger David Ortiz, who’s known as Big Papi.

“It’s neat,” said Ortiz, who had his arm around Giddon and gave him an autographed bat.

Giddon was introduced to the crowd along with Wally the mascot before the ceremonial first pitch by Olympic sprinter Usain Bolt. A resident of Bloomfield, Conn., Giddon recalled how he felt when the Red Sox won their first World Series in 86 years back in 2004.

“I went crazy. My wife thinks I’m going to go insane,” Giddon said. “We have a huge TV and I’m screaming and yelling.”

Clearing the bases

The Kansas City Royals activated outfielder Jose Guillen from the disabled list. He had been out with a partially torn right hip flexor tendon. … Minnesota Twins catcher Joe Mauer could rejoin the club as early as Tuesday after spending time on the DL with a sore lower back. … The Atlanta Braves have placed catcher Brian McCann on the 15-day DL with a left eye infection.
