Which is before he ever has an AB in a Brewers uniform, so yes, he is 30 as far as we are concerned. It's about optics. 29 going on 30 sounds better than 30 going on 31, which is what Simba's post would lead most to believe. But yes, Renfroe will be playing in his age 30 season in 2022. While determining what a player's "prime" years are is FAR from an exact science, this article from the Boston Globe (https://www.bostonglobe.com/sports/2015/01/02/what-baseball-player-prime-age/mS39neFWm4hrVukT6lSYuK/story.html) indicates a player's "prime" lasts until they are approximately through their age 30 season. So, by that definition, Renfroe is still in his prime, but on the tail end of it. But, he was obviously a late bloomer (which explains why he is still arby eligible through 2023 at his age), so who knows? Wow, this offseason is going to really suck for awhile, isn't it?
