Capps to sign with Nationals or Cubs

Free agent righty expected to decide by Wednesday

WASHINGTON -- Free agent right-hander Matt Capps will sign with either the Cubs or Nationals, according to his agent, Paul Kinzer. Capps is expected to make a decision on Wednesday night.

"[Nationals general manager] Mike Rizzo has done a great job [this offseason]," Kinzer said via phone.

If Capps joined the Cubs, he would become a setup man. If the Nationals acquire his services, Capps would battle Brian Bruney for the closer role.

When reached by phone last week, Capps said it didn't matter what role he had if he joined the Nationals.

"If it's better suited for me to set up for the team in the seventh inning or eighth inning, that's what I'll do," Capps said. "If they sign me and tell me they want me to play shortstop, I'll play shortstop. I want to win. I want to be in an environment [where winning is important]. All signs are looking good with what they are trying to do so far."

The Nationals are in need of bullpen help. This past season, Washington relievers posted a 5.09 ERA, which ranked 30th in the Majors.

Capps has spent his five-year career with the Pirates, collecting 67 saves while posting a 3.61 ERA. He was non-tendered by Pittsburgh on Dec. 12.
