I think Takatsu will close. Guillen is in love with using Marte as his specialist...meaning, he faces the top lefty in the opposing lineup, whatever inning it is in.
Takatsu has been great this year. Politte, not so much. I love Marte, he's my favorite MLB player, but I think Takatsu is next. Keep an eye on the situation. Billy's stuff hasn't been that bad, but his confidence is terrible. I'm stupid enough to start Koch and Marte right now...but oh well.
