Greg Holland, Royals: The theme of the week appears to be speculation plays, as rumors are swirling that Jonathan Broxton could be on his way out of town. There are plenty of good options in the Royals bullpen to assume the role, but Holland could be the first in line to collect saves if Broxton is ultimately dealt. Also keep an eye on Kelvin Herrera, who could vulture saves as well.
Wilton Lopez, Astros: A contender could scoop up Myers based on his experience and track record at the trade deadline, creating a ninth inning vacancy in Houston. Brandon Lyon is still in the mix, but he could also be on the move, so we look to Lopez as the guy to assume the closer role. Fresh off the disabled list, if he proves healthy and effective, Lopez makes the Astros' decision to move their veteran arms could become much easier.
Glen Perkins, Twins: Matt Capps is on the trade block, and if he's dealt, Perkins could be the permanent ninth inning replacement in Minnesota. He's converted 4-of-5 opportunities since Capps went on the disabled list, and is a far better option than Jared Burton. He's a great speculation play with the trade deadline fast approaching.
Bobby Parnell, Mets: Frank Francisco is still feeling pain in his injured oblique, thus providing Parnell more opportunities to seize the closer role permanently. He's a hard thrower who has always had the potential to be a shut down closer, but seems to slip up when given an opportunity to shine. He should stick in the role for at least another 2-4 weeks, provided the Mets don't acquire a closer at the trade deadline (with Broxton being a name thrown about).
Steve Cishek, Marlins: Juan Carlos Oviedo suffered a setback during his minor league tune up, and Heath Bell has been awful, so let's have a look at Cishek. He picked up a five out save on Saturday, and has a tidy 2.08 ERA on the season. With the Marlins bullpen a complete mess at the moment, Cishek is certainly worth a look.
