I'm not a huge baseball fan, but my favorite baseball player of all time would have to be former pitcher Tim Wakefield. Where I was living in the early '90s didn't have a Major League team, but Atlanta was closest, and being a Braves fan suddenly became a very fashionable thing to do around where I was.
It actually got very annoying that suddenly everyone was a bandwagon Braves fan. It hit a high-pitch during their National League Championship Series versus the Pittsburgh Pirates, which happened to be one of only two teams I'd ever seen play in person. Not wanting to go along with everyone else around me (particularly my family), I decided to start rooting for the Pirates.
Wakefield made the series truly interesting with his unpredictable knuckleball pitch, winning both his starts against Tom Glavine. The Braves eventually won the series at the last minute, but I did get to rib Braves fans for quite a few more mornings than they expected or wanted.
Wakefield eventually was released by the Pirates and found a career second wind with the Boston Red Sox. He won two World Series with them.
