The Brew Crew is only gonna improve. As it is, Sheets has been unlucky with run support, as the team has been getting lots of hits when he pitches, but they have been spread out over the game, with many left stranded.
One thing Sheets can do to help himself is learn to hit better or at least bunt. He is the WORST hitter I've ever seen and can't even bunt well. I can't tell you how many rallies I've seen him stop cold this year with a terrible at-bat or a lousy bunt.
I am the Master. Don't question the Master. Just do what he says and be proud.
