Washington Nationals second baseman Junior Spivey fractured his right radius -- a bone in his forearm -- while taking batting practice off a tee prior to Saturday's 1-0 loss to the Philadelphia Phillies, an injury that will keep him out between two and three months.

Spivey, who was not in the original lineup against the Phillies, said a ball ricocheted off the framework of a net into which he was hitting and careened back into his wrist.

"I was hitting off the tee, and the ball ricochets off the pole," Spivey said. "It hits me. I didn't think nothing of it. But I took some swings, and that's when I felt it pop."

Wiemi Douoguih, the Nationals' orthopedic surgeon, said Spivey will undergo surgery Monday morning at Washington Hospital Center. He will be placed on the 15-day disabled list after the all-star break.

Infielder Tony Blanco, who is suffering from vertigo-like symptoms stemming from a sinus infection, is also a candidate to be placed on the disabled list after the break. If both Spivey and Blanco go on the disabled list, they are likely to be replaced by outfielder Ryan Church and first baseman Nick Johnson, who are both on rehabilitation assignments and should be ready immediately after the all-star break.

That leaves Manager Frank Robinson with a short bench for Sunday's finale against the Phillies. With shortstop Cristian Guzman nursing a sore hamstring, Robinson's bench Saturday and Sunday consists of Wil Cordero, Marlon Byrd and one catcher, either Brian Schneider or Gary Bennett.

During a key situation in the top of the eighth on Saturday, Robinson had his starting pitcher, John Patterson, stay in the game to bunt, at least in part because -- in a scoreless game -- he didn't want to use one of his available hitters.

"Why would I waste a hitter on a bunt now?" Robinson asked. "I'm short-handed as it is. That's the whole thing."

Spivey was acquired from Milwaukee in a trade for pitcher Tomo Ohka on June 10 to fill in for starting second baseman Jose Vidro. When Vidro, out with ankle problems, returned this week, Spivey went to the bench and his immediate role was in question. He hit .221 with two homers and seven RBI in 77 at-bats, but he struck out 26 times and was slumping badly.

Blanco began feeling dizzy in the middle of this week, and said the condition wasn't improved on Saturday.

The injuries won't impact the Nationals' roster long-term. Johnson, out with a deeply bruised heel, and Church, out with shoulder problems, should both be back from Class AA Harrisburg for the first game after the break, Thursday in Milwaukee.

Spivey, however, won't be there to face his former team.

"It's frustrating," Spivey said. "I don't know how to even describe how I feel right now."
