The Orioles placed rookie utility man Ryan Flaherty on the disabled list Wednesday so he can recover from a bacterial infection.

Flaherty was sent home early during Tuesday's game with tonsillitis and a 103-degree fever. The club was concerned Flaherty might have mononucleosis, but tests done Wednesday ruled that out. He still had swollen glands, but no longer had a fever. The team sent Flaherty home again Wednesday to get rest.

"The next three days are pretty important, because it could turn into something pretty serious there, more than just tonsillitis with the infection," Orioles manager Buck Showalter said. "So we sent him home [Wednesday]. The temperature has pretty much abated, but he said the next 24-48 hours are very key for him not to get into some serious stuff."

The DL move is retroactive to Thursday — Flaherty last played Wednesday in New York as a substitute — so he is eligible to be activated Aug. 17. Showalter said he hoped Flaherty would be able to join Single-A Frederick for a rehab assignment this weekend.

Flaherty, the Orioles' Rule 5 draft pick in December, has a .205/.242/.308 line with four homers and 11 RBIs in 60 games. He's played six positions and served as the team's DH, but he hasn't started since July 23 at Cleveland — mostly because of the Orioles' acquisition of infielder Omar Quintanilla.

The Orioles added an extra right-handed bullpen arm to fill Flaherty's spot on the 25-man roster, recalling rookie Miguel Socolovich. The O's used six relievers over nine innings in their 14-inning win over the Seattle Mariners on Tuesday night.

Entering Wednesday, Socolovich pitched to a 9.00 ERA in four major league outings this season. He was 4-0 with a 1.90 ERA and 52 strikeouts in 52 innings pitching for Triple-A Norfolk.

This is the third time the Orioles have added Socolovich — his first stint was three days and his second was just one day — and Showalter said it was unclear how long the 26-year-old would stay this time.

"It's going to be a day-to-day thing," Showalter said before Wednesday's game. "We'll start talking about some things after the game tonight, but we've got to wat and see how it all shakes [out]."
