"It just means I'm going to be in the same company with Jose Mesa and Francisco Cordero," Rodney said of getting to 300. "That's the most saves from Dominican closers right now. I'm going to be in the same group as those guys."
Rodney, 40, will tie Bruce Sutter and Jason Isringhausen, who each have 300. Mesa has 321 and Cordero has 329.
If Rodney saves two more games, he'll become just the second pitcher to collect 40 saves in a single season at age 40 or older.
"I didn't know that," Rodney said. "There are a lot of numbers in baseball. Sometimes you just focus on what you've been doing in the season. That's been my plan. Just try to get as many as I can, and then, when the season is done, you can count."
Rodney has pitched 15 years in the big leagues, and leads all active relievers with 824 appearances. How does he explain his longevity and durability?
"I don't know," Rodney said. "I think I do a regular routine every season. I still eat the same and work out, and do my throwing program. I don't do anything else. I work out a little bit in Miami, or maybe the Dominican, in November and December, and then, after that, I start to play catch and play long toss. I feel good. That's the most important thing. I feel blessed and thank God. I like what I do, and I'll just keep doing."
Shortstop Chris Owings, who has been on the 60-day disabled list with a fractured right middle finger, is scheduled to see hand specialist Don Sheridan on Friday.
Owings is eligible to come off the DL on Sept. 29, and manager Torey Lovullo is optimistic that Owings will play the final three games of the season in Kansas City. The only question mark is whether Owings can get enough at-bats to be ready for game action, considering that Minor League seasons have ended.
"Friday's re-examination will show what level they want to go to next," Lovullo said. "I think he put a bat in his hands and took some dry swings, which is always a good sign."
