A speedy type, his 24.2 percent strikeout rate in the majors last season would lead to low batting averages characterizing him as a one-category rotisserie performer. But Mastroianni, if he emerges, could be a cheap AL-only steals target, being that he has historically drawn a high rate of walks -- 11.6 percent career in the minors, 9.7 percent for the Twins in 2012 -- which will lead to plenty of times on base to run.","seasonId":2013,"date":"Wed Feb 20"},"positionRank":149}
