The San Francisco Giants hope they’ve found what was driving Noah Lowry wild.

A day after Lowry walked nine of 12 batters, he was diagnosed with tendinitis in his left wrist Tuesday and sent home to San Francisco to see a hand specialist.

“You go out there and you want to compete at the level that you know you’re capable of competing at and sometimes your body doesn’t allow you to do that,” he said. “At this level you have to be right physically. Right now it’s not.”

Lowry was 14-8 with a 3.92 earned-run average last year before a bone spur in his left elbow cut short his season in late August.

In his first start this spring, he walked three and threw two pitches to the backstop while giving up three runs in 11â3 innings. On Monday, only four of his first 40 pitches were strikes against Texas.

A series of tests revealed the tendinitis.

“It looks like we’ve identified the problem,” Giants manager Bruce Bochy said. “I didn’t know anything about it. I don’t think anybody was aware.”

Lowry will take anti-inflammatories and wear a splint on his left thumb for the next few days.

“They feel by the weekend, if we stay away from any kind of use with my wrist, that hopefully we can turn the corner on this,” Lowry said.

By comparison, Greg Maddux threw 16 of his 18 pitches for strikes Tuesday.

Maddux pitched two hitless innings as San Diego beat the Giants, 9-6.
