Reds option Frazier to make room for Simon

CINCINNATI -- Infielder/outfielder Todd Frazier broke camp with the Reds on Tuesday and thought he was going to start the season in the Majors. Sometimes the business-side of baseball deals a rough hand.

One day before Opening Day, Frazier was optioned to Triple-A Louisville to make room on the 25-man roster for Alfredo Simon. The right-handed reliever was claimed off of waivers from the Orioles on Tuesday.

"That's a very tough move," Reds manager Dusty Baker said. "It happened to me. I know how it feels from morning to afternoon. I was told in the morning that I made the team. After I hit a couple of home runs, I came back in and everybody was silent. They said 'Dusty, they want to see you in the office.' They told me that they changed their mind. I had already sent my car north to Atlanta and I was on my way to Richmond."

Frazier had an outstanding Spring Training, batting .291 with a team-leading five home runs and 15 RBIs.

"He's the best I've seen him since I've been here," Baker said. "It's the best start he's had since I've been here. He's right there knocking at the door."

Frazier was told that he would primarily play third base at Louisville, and he could be potential insurance down the road should something happen with regular third baseman Scott Rolen. At the big league level, Miguel Cairo, Willie Harris and Wilson Valdez could all fill in for Rolen.

"He'll still play some first base and some corner outfield, but mostly third," Baker said of Frazier. "That is the position he needed the most reps at, possibly for his sake and our sake."
