Unless appealed, the suspension of Capps will begin on Tuesday, when the Pirates are scheduled to play the Cubs at Wrigley Field. If appealed, the pitcher's suspension will be held in abeyance until the process is complete.
After giving up a three-run homer to Milwaukee shortstop J.J. Hardy in the seventh inning Saturday, which was only the second time Capps had allowed a run all year, Capps hit Fielder in the arm and was ejected by home-plate umpire Alfonso Marquez.
"[Marquez] felt like he was intentionally throwing at him," Pirates manager Jim Tracy said after Saturday's game. "I don't think that's the character of Matt Capps. The call and the circumstances that transpired prior to that ... he's concerned that it could have been intentional, and you potentially get in a situation where you completely lose control of a baseball game."
Capps' 0-1 pitch to Fielder was near the first baseman's head and glanced off his raised arm.
"I had him 0-and-1," Capps said. "So he had a quick hook. Obviously, stuff like that is a judgmental call on his part, and I'm not going to question what he did. I have to show him I can pitch inside. If they don't like it, that's their problem. I'm going to continue to throw the ball on the inside part of the plate."
