ATLANTA -- Giants closer Brian Wilson is expected to be sidelined for at least two days with inflammation in his throwing elbow, manager Bruce Bochy said Wednesday.

Wilson received the diagnosis from Dr. James Andrews during a Wednesday trip to the famed orthhopedist's office in Pensacola, Fla. Bochy said that Wilson felt some discomfort in his elbow Monday night, when he allowed three ninth-inning runs and blew a save opportunity in the Giants' 5-4 loss to Atlanta. Bochy added that Wilson still didn't feel right Tuesday, prompting his visit to Andrews, who performed Tommy John elbow surgery on the right-hander in 2003.

Andrews' examination verified that Wilson's ailment was not serious.

"It showed just a little inflammation," Bochy said.

Bochy sounded confident that Wilson will encounter no long-term ill effects but noted, "We didn't want to risk putting him back out there without getting evaluated."

Wilson was due to rejoin the Giants in time for Wednesday night's game against Atlanta.

"I'm sure he's going to want to pitch tonight, but we'll give him a couple of days off -- two or three days," Bochy said.

Wilson, a three-time National League All-Star who began this season on the disabled list with a strained left side, has a Major League-high 162 saves in the last four seasons. This year, Wilson has converted 35 saves in 40 chances, though he has fallen short of his previous standards in other statistical categories. His 1.491 WHIP (walks and hits per inning pitched), 5.2 walks per nine innings and 1.68 strikeout-to-walk ratio are his worst since his 2006 rookie season. His average of 8.7 strikeouts per nine innings, while respectable, pales alongside his corresponding figures from 2010 (11.2), 2009 (10.3) and 2008 (9.7).

The reigning World Series champions already have been beset by injuries that have affected their lineup, bench, starting rotation and bullpen. Right fielder Carlos Beltran (right hand) and right-handed reliever Sergio Romo (elbow) are on the 15-day disabled list. Second baseman Jeff Keppinger is stymied by a right wrist injury. Third baseman Pablo Sandoval and right fielder Nate Schierholtz are hobbled by bruised right feet. Outfielder Aaron Rowand (strained left side) is limited. No. 5 starter Jonathan Sanchez is nursing a sprained left ankle.
