Baseball Toaster was unplugged on February 4, 2009.
There was more activity on SABR-L regarding Pete Rose being on the most winning teams.
In any event, what is amazing is that Pete Rose came within just a few games, probably less than 10 wins (3500+ games played) from having a winning record for 24 straight years! Of course, someone could spin it that Pete was also one of the biggest losers, given that he probably lost 1500 games.
Re. Rose, his teams did have the most winning seasons recorded for a player all time, but he is just two seasons ahead of the likes of Doyle Alexander, Rick Dempsey, and Juan Pizzaro. Here are the ones with at least 18 winning seasons:
