Deunte Heath being sent down to AAA right before the All-Star break dropped the roster count down to 24, and Philip Humber is set to take his roster spot for a start on Tuesday.
But that's Tuesday. It is presently Friday. Philip Humber is of no use this weekend.
Marinez is yet another Charlotte Knights reliever who's seen some improvement in his control this year. He has a 3.14 ERA in 43 innings (most of any Knights reliever), while striking out 47 and walking 20.
4.19 BB/9 isn't spectacular, but since Marinez is likely only here for three days as bullpen depth--should there be some orgy of offense in Kaufmann Stadium--the extent to which his adjustments will be tested should be minimal. There certainly will be nothing high-leverage without extra innings or poor bullpen telephone reception being involved.
Besides piles of cash of various sizes, Marinez is the last holdover from the Ozzie Guillen trade. He's got a big arm and a wipeout slider that the White Sox felt they could reform, but since he was behind Brian Omogrosso and Brian Bruney in line, it's likely they haven't quite finished the job yet.
