Re: CF Drew Stubbs
As it with most baseball statistics, there is more to it than simply OBP. Dickerson is an excellent 2 hitter. Batting LH, with Stubbs a threat to steal on first, forces the defense to hold Stubbs and opens up the right side of the infield for Dickerson. It also gives the opposing pitchers two things to worry about. Dickerson is likely to see more fastballs as a result.
Of course, this presumes that Stubbs is as productive this year as he was last year. If his OBP is low, all bets are off. Still, in mid-Feb, batting Dickerson behind Stubbs looks like a good plan.
