Using their seasonal June 30th ages, here are the players to hit 40+ homers at least once at the age of 29 or older who never did it at age 28 or younger:
In this case, the 'years' column refers to the number of times they hit 40 HR after the age of 29. Of these 45 guys, the most recent to do it was Jose Bautista last year. Bautista is a more interesting case since he never had more than 16 HR in any previous season.
If we whittle down the list to guys who never hit more than 20 before age 29, then we're left with just 7 names: Bautista, Cy Williams, Davey Johnson, Hank Sauer, Ken Caminiti, Luis Gonzalez, and Dante Bichette.
Those wondering how I did this search--first I did a batting season finder for guys Age 29 and older with 40+ seasons, and then I used that search result as a basis for two new batting season finder searchers (for players 28 and under with 40+ or 20+ HR seasons). I then had to compare the lists manually to see which names were missing, but it took only a few minutes since the first search eliminated so many names.
