SAN FRANCISCO -- Right-hander Vinnie Chulk was back in the Giants clubhouse Sunday morning, getting ready for what he hopes is his season debut Tuesday.

Chulk, recovering from a right shoulder strain, has been on the disabled list since March 21, after making five spring appearances. He's had enough of that.

"That's basically not where you want to be: on the DL," Chulk said. "I've been working hard to get back. It's been unbelievably frustrating."

He won't have to wait too much longer. He pitched at Triple-A Fresno again Saturday, giving him back-to-back appearances for the first time and is scheduled to return to action Tuesday, when the Giants host the Arizona Diamondbacks.

"It looks like he's ready to go," Giants manager Bruce Bochy said.

Chulk appeared in four games with the Grizzlies, pitching 4 1/3 scoreless innings. He gave up two hits and struck out two.

"It felt like I was starting all over again," Chulk said. "I'm feeling pretty comfortable. It's getting close."

Chulk was 5-4 with a 3.57 ERA in 53 games with the Giants last year.
