Beller: For me, it's Pedro Strop. It would be a complete shock if the Cubs didn't trade Kevin Gregg by next week, and manager Dale Sveum said Strop is likely to take over ninth-inning duties if and when Gregg is shipped out of town. Strop has made nine appearances with the Cubs since being part of the trade that sent Scott Feldman to the Orioles, and has yet to allow a run. He has 10 strikeouts against two walks in 7.2 innings in that stretch. If you're looking for a guy who isn't closing now but might be next week, he's your best bet.
