Here's a small sample size player comparison but its one I want to track all season:
Player A - 0 R/ 0 HR/ 0 RBI/ 1 SB/ .000 BA/ .222 OBP/ .222 OPS
Player B - 1 R/ 1 HR/ 1 RBI/ 0 SB/ .250 BA/ .250 OBP/ .875 OPS
Player A is Jacoby Ellsbury who had a planned day off yesterday and Player B is Grady Sizemore who also had a day off yesterday. I have nothing against Ellsbury but the Sizemore story is so great that this comparison warrants special attention during the season.
