I do not see any real skill set in Arakawa's game. If anything he's a utility guy on the infield. A replacement for Pennington after next season?
I'd rather see Sherman Johnson who can play 2B, 3B and the outfield. He gets on base, has some speed and pop.
Sherm's numbers so far this season are much better than last season. .276/.369/.473/ and an OPS of .842 w/ 8 HR, 9 SB so far on the season.
Cal Towey is looking good though. .294/.407/.455 is not too shabby. Would like to see more power though (only 4 HR, the most he's hit in a season is 10).
