Right-hander Byung-Hyun Kim was signed by the Marlins as a free agent on Saturday, less than one month after they had placed him on waivers.
"He enjoys pitching in South Florida," said Marlins manager Fredi Gonzalez. "He enjoys being around the guys here. I think it'll be a good thing."
Gonzalez later joked: "We haven't been the same without him."
The Diamondbacks claimed Kim off waivers from the Marlins on Aug. 3, then released him on Aug. 15 after he retired just one batter in a 14-5 loss to the Marlins. Kim was pulled from that game after making just 17 pitches. He made only two starts for Arizona before being let go.
To make room on the roster Saturday, the Marlins optioned right-handed reliever Ross Wolf to Triple-A Albuquerque. Wolf was 0-1 with a 9.64 ERA in six appearances for Florida.
Kim, who has not pitched in a game in nearly two weeks, was expected to arrive in Cincinnati in time for Saturday's game. He'll wear uniform No. 23.
"It's been a while since he's thrown," said Gonzalez. "We'll throw him out of the 'pen the next couple of days. We'll see where he's at and how he feels."
This season, Kim is 6-6 with a 5.23 ERA in 19 appearances, including 16 starts, for Colorado, Arizona and Florida.
Gonzalez said the addition of Kim could help limit the innings of his young starters, namely Rick VandenHurk and Daniel Barone.
"We'll run one of those guys into the bullpen and flip-flop them," Gonzalez said. "[Kim's] very flexible. We can run him in the bullpen until he gets ready."
Boone's season over: Marlins third baseman Aaron Boone said on Saturday that he will have season-ending arthroscopic surgery on his left knee on Sept. 4.
Boone, who has been on the disabled list since June 25 with a left knee sprain, signed a one-year $925,000 contract with the Marlins in December.
At the time of the injury, Boone was batting .286 with five home runs and 28 RBIs in 69 games.
"It's frustrating because I felt like I had a minor injury," Boone said.
According to Boone, the procedure will be performed by Dr. Timothy Kremchek of Beacon Orthopedic in Cincinnati. Kremchek is the medical director for the Reds, with whom Boone played seven seasons.
"It was good to see him," said Boone of Kremchek. "I feel like I've got some answers. I know what to expect. It's a matter of getting scoped and getting on a rehab program."
Boone, who missed the entire 2004 season after having surgery on the same knee, feels he still has a few productive years remaining in his big-league career.
"I was playing well at the time of the injury," Boone said. "I have a pretty good outlook on things. I'm still playing for the right reasons. Going into this year, I was taking it one year at a time. I'm looking forward to playing next year."
Concepcion honored: The Reds retired former shortstop Dave Concepcion's uniform No. 13 prior to Saturday's game at Great American Ball Park.
Concepcion, a nine-time All-Star and five-time Gold Glove Award winner, joined Hall of Famers Sparky Anderson, Joe Morgan, Johnny Bench and Tony Perez in a pre-game press conference.
Perez, a special assistant to the president of the Marlins, was Concepcion's teammate on Cincinnati's Big Red Machine clubs which won two World Series, four pennants and five division titles during the 1970's.
"[Perez] was like a brother to me," said Concepcion. "We roomed together for six years. I'd like to thank all of my teammates. You're not going to see a better team than the Big Red Machine."
Third baseman Miguel Cabrera, the lone native Venezuelan on the Marlins' active roster, idolized Concepcion. He grew up in Concepcion's hometown of Maracay.
"He deserves all of the honors," said Cabrera. "He's a big hero in Venezuela. I grew up watching videos of him. I wanted to be like him. I'm glad to be here today for him."
Birthday wishes: Dave Van Horne, the play-by-play voice of the Marlins for the past seven seasons, celebrated a birthday on Saturday.
