p.alvarez, r. roberts, or c. johnson @3B

[wmenchen]

with sandoval going down i have to start one of these guys. obviously roberts is playing over his head and alvarez and johnson are slumping to start the season. which guy do you think has the most value till sandoval gets back. *note roberts was playing for mora and he's back now. i know roberts stats are way better than the other 2 guys, but i would hate to start roberts and him come back to earth while the other guys go on hot streaks.
any input would be helpful.
thanks
