PEORIA, Ariz. -- Two days after he sparked a benches-clearing brawl in the World Baseball Classic, reliever Arnold Leon was back in A's camp -- for all of a few minutes, anyway.

Leon returned to the A's on Monday morning, only to find out that he had been optioned to Minor League camp, where he will continue to get work while prepping to start the season with Triple-A Sacramento.

The move was not made to punish Leon, who plunked Canada's Rene Tosoni in the back near the end of Team Mexico's eliminating 10-3 loss Saturday. There just are not enough innings for him in Major League camp anymore, manager Bob Melvin said.

The right-handed Leon made three Cactus League appearances for the A's before joining Team Mexico, allowing a combined two runs, three hits and four walks with one strikeout in three innings of work.

Oakland now has 46 players in camp, including 37 on the 40-man roster and nine non-roster invitees.

Rodriguez exits Padres game with elbow soreness

PEORIA, Ariz. -- A's reliever Fernando Rodriguez exited Monday's game against the Padres with right elbow soreness after throwing just seven pitches in the sixth inning.

Making his fourth appearance of the spring, Rodriguez walked a batter and was seen latching on to his pitching elbow. Shortly after, he departed the field with a trainer.

Because the injury surfaced in the later innings, manager Bob Melvin was without much more information after the game and unsure whether the right-hander would have an MRI test.

Rodriguez, acquired in the Jed Lowrie trade, has given up a combined three runs and four hits in 2 2/3 innings this spring. He is unlikely to make the team out of camp, with so few bullpen spots open for so many relievers.

Weeks will play in Minors before rejoining A's

PEORIA, Ariz. -- Don't expect to see Jemile Weeks back in a game until at least Thursday.

A big league game, that is. Weeks, nursing a bruised right shoulder back to health, played five innings in a Minor League game Monday and is scheduled to do so again Wednesday after resting Tuesday.

That means Weeks will not be return to the A's lineup until Thursday or Friday, if all continues to go well, making it two weeks since the second baseman has played in a Cactus League game.

Weeks has picked up only 11 at-bats spanning four games this spring, seemingly putting him behind in the second-base competition next to fellow top contenders Scott Sizemore and Jed Lowrie.

On Monday, Weeks had no balls hit to him in five innings. He flied out to center twice, walked once and grounded out to first.

Worth noting

• A's lefty Travis Blackley was knocked around for four runs on five hits in just 1 1/3 innings on Monday, just over a week after giving up seven runs in one-third of an inning. Melvin, though, does not appear worried about the southpaw, who is fighting for a job in the bullpen, noting Blackley's other two appearances have been strong.

• The A's compiled just four hits against San Diego's pitching staff Monday. Not surprisingly, one belonged to outfielder Shane Peterson, who went 1-for-2 to raise his spring average to .471. The A's prospect is the only player to appear in each of the club's 15 games this spring, and he has 16 hits in 34 at-bats over that span.
