"Like an absolute pro. Like a professional," Matheny said. "Everybody around here is watching and acknowledging and admiring."
Freese -- the 2011 World Series MVP -- entered Monday with career lows in batting average (.265), on-base percentage (.343) and slugging percentage (.380) to go with six home runs and 43 RBIs in 103 games this year.
But Matheny said he is not overly worried, noting Freese would be in the starting lineup for the final two games in Milwaukee.
"David's going to be right back in there," he said. "He's going to be in there tomorrow and he's going to be in there on Wednesday. Hopefully it gets him a little rest and hopefully this will all work out and he gets on a tear a bit. He's handling it as well as anybody possibly could."
