Frazier, who came up through the Reds' system primarily as a left fielder, has played first, second, shortstop, left field and mostly third base in his two seasons with the Reds. He's now tasked with filling in for the injured Scott Rolen.
"There are very few people in the history of the game that have played third base like Scott Rolen's played third base," Baker said.
But in 41 games with Cincinnati this season, Frazier -- a New Jersey product, returning close to home this weekend to face the Mets -- is hitting .273 with seven homers and 22 RBIs.
"That was one of the reasons he was playing so many positions -- everyone was trying to figure out which one he's best at," Baker said. "And the one he was best at was hitting. After that, we tried to find a place that's gonna be right for him and right for us."
Rolen, out since May 12 with a strained left shoulder, will play two rehab games with Triple-A Louisville before likely returning Monday in Cleveland. When that time comes, Baker expects to continue to find places to use Frazier.
"We're gonna get him in there," Baker said. "He's earned that right to play, because he's really performed well, especially performed well in run-producing situations. He's not afraid, he's not intimidated by any situation. That's what you like to see in a young guy."
