I was wondering if John knows anything about Boone Logan.  Nothing special until last year when he was switched from a starter into a reliever and posted the following line in Great Falls (Rk):

35.1 IP / 29 Ks / 4 BB / 1 HR

Not only did his switch to the bullpen help, but he started using a 3/4 delivery.

He impressed Chicago in minor league camp this Spring when he K'd Mackowiak and Thome.  He was invited to the Major League camp and has been scoreless in 4 games.  

It looks like he might end up making the team Opening Day as one of the arms in the bullpen.  I was skeptical (and to a certain degree, still am), but I saw him pitch yesterday and he did look impressive.  He throws nothing but strikes and gives up nothing but groundballs.  He also was hitting 93 with his fastball.

Any thoughts on Logan?  How rare is it for a guy to go from nobody in Rookie ball to Opening day roster?
