Nice work.
Make sure you're maintaining your flexibility, and don't let your bench get stronger than your row. Also, as Al420 mentioned, you really have to take care of your rotator cuffs.
Somebody correct me if I'm wrong, but if you're a pitcher, it's more important to be flexible than it is to be strong. Remember what happened to Jose Canseco when he tried pitching? A a pitcher, you have a lot more to worry about than most of us do. A lot of us (guys on these forums) can bench more than any ML pitcher can, but none of us has a decent fastball.
