Leury should be just fine, as a platoon partner for Mazara. He hits lefties well enough to cover those games, as his performance over the last 3 years indicates:
AVG OBP SLG
.302 .341 .349
.333 .349 .444
.311 .344 .443
Given his speed and versatility, he is probably as good as some of the other names, which have been suggested, in the limited role of Mazara's platoon partner, especially when considering the cost. I'm much more interested in additional pitching depth, than I am concerned about acquiring a guy to take 100 + at bats from Mazara. In fact, I'd kind of like to know if Mazara can learn to hit lefties better. If Nomar realizes his potential vs. RH pitching, it would be helpful to know if he would still need a platoon partner, going forward, should the Sox have an interest in extending him.
