i'd normally agree, but the blue jays are not in 'development mode' right now. we are in win-now mode, which means that we should use any and all resources to win. pompey is a better hitter left handed bottom line. was in the minors, and in his short stint in the majors. he will get enough major league ABs in garbage time and short bench situations to work on his right, and when he shows he can hit better than pillar right handed, he will win the job outright. until then, pillar is putting up very respectable numbers on the right side with apparently very respectable defense as well.
i think this is AA's plan for CF, and LF and 2B will need to be addressed.
as for 1b, i think it will be a valencia/smoak platoon and will remain that way until it becomes a disater or someone gets hurt.
