Robin

From MLB Power Pros Wiki

Robin is the little brother of Robert. He joins the Tulip's in August of the 3rd year. He's a talented pitcher, a worthy reliever to Alvin during games. Robin's top speed is actually better than Alvin's, but his secondary pitches are just that - secondary, both being 1's. His personality leaves a bit to be desired, being a bit of a loudmouth and an acute case of attention-deficit disorder, but he makes up for it with tips of getting items and raffles.
