Recently, I read a couple articles online about a guy who was in spring training with the A's, Pat Venditte. His is a neat story about growing up with a dad who was so supportive of his love for baseball, that he built lil' Pat a state-of-the-art batting cage in his backyard. As sort of a long-term experiment, Pat Sr. taught his kid to pitch with both hands growing up. It worked to make Pat Jr. a true ambidextrous "switch-pitcher." He's got a special glove so he can switch hands depending on who he's facing.
Being a fan of quirky stuff like this, I thought that was pretty cool. While his pro career hasn't exactly been a fairytale-- he's now 29 years old, with 7 years in the minors under his belt (b-r stats)-- he seems to be on the cusp of making the show, I believe currently with Oakland's AAA affiliate. I went looking to add a good card of his to my collection, and ended up bringing this auto home for a few bucks:
Despite being a sticker auto, it's a really nice looking card, with some purdy refractor shine on the front and #'d 041/199 on the back.
Best of luck, Pat! It'd be pretty neat to see you switch-pitching in the majors sometime soon.
