"Just an honor," said Cash, when asked what the milestone meant to him. "You don't want to dwell on too many personal accolades, but it is, it's an honor to say you're a big league manager."
Lou Piniella was the previous record-holder, having reached the mark in his 235th game as the Rays' skipper.
Over the last 25 years, only two managers have reached 100 wins at a younger age: Eric Wedge -- with Cleveland in 2004, at 26 years, 141 days -- and Buck Showalter -- with the Yankees in 1993, at 36 years, 364 days.
