As expected, Drew Pomeranz was quite nervous in his major league debut. Only, not on the mound, but with a bat in his hands in his one and only plate appearance. Even then, Pomeranz was a success, laying down a perfect sacrifice bunt. It was just that kind of day for the prized prospect. Pomeranz threw five shutout innings and Ty Wigginton homered, helping the Colorado Rockies to a 4-1 win over the Cincinnati Reds on Sunday.
