Left-hander Sean Burnett wasn't available to pitch the past two nights, and he won't be back until Thursday at the earliest after experiencing stiffness in his left forearm.

"I've been dealing with it off and on the last two weeks," said Burnett, who threw an inning in the Angels' 13-inning win over Detroit on Sunday. "I'm just playing it safe."

In part because of Burnett's injury, in part because long reliever Jerome Williams is expected to start today, the Angels recalled left-hander Nick Maronde from Double-A Arkansas on Tuesday. Infielder Tommy Field was optioned to Triple-A Salt Lake to make room for Maronde on the 25-man roster.

That left the Angels with nine relievers and only three position players available off the bench. Manager Mike Scioscia said it's the first time he can recall having that many relievers at his disposal, let alone four left-handers (including Burnett).

It's all but a necessity. Angels starters are averaging slightly less than 52/3 innings per start through Monday, which ranked 12th out of the 15 American League teams.

"I think it's less risk for your overall team if you're short on pitching," Scioscia said. "There's no doubt we've gone through a lot of pitching. With the extra-inning game (Sunday) in the Detroit series and (Monday) night, we need that fresh arm at times and this is one of those times."

The Angels used four relievers in a 7-6 loss to the Texas Rangers on Monday.

Burnett had surgery to remove bone spurs in his left elbow last October and he explained the tightness as a symptom of the recovery process. It's worth noting that Burnett made a team-leading 10 appearances in the Angels' first 17 games, which has him on pace to pitch nearly 90 games this season.

Burnett doesn't expect to keep up that pace, but he isn't complaining.

"The workload's been fine," he said. "It's more frustrating than anything. When I get out there I feel good."

Maronde appeared in six games with Arkansas, allowing five runs in 72/3 innings (a 6.14 ERA). Field got into three games as a defensive replacement for the Angels without getting a plate appearance.

Williams would be starting in place of Tommy Hanson, who was placed on the bereavement list Monday.
