Axford, the Brewers' second-year closer who was mentored last season by Hoffman, called it "huge." Rodriguez, the single-season record-holder with 62 saves, called it "ridiculous."
"I remember specifically trying to think about how big a number 600 was and how you get to that number," Axford said. "That's 40 saves every year for 15 years. It's mind-boggling when you think about it, and both of those guys have done it."
Rodriguez is fourth among active pitchers with 291 saves, though he has been pitching exclusively as a setup man to Axford since a July trade from New York.
He found 602 saves hard to fathom.
"It seems ridiculous," Rodriguez said. "It's hard to imagine. It's a lot of work, a lot of sacrifice and a lot of years -- consistency. It's not easy. ... It's something that's hard to think about."
