Final two Cubs reliever spots?

Patton had a 1.26 ERA and 15 SO's in 14 innings. Gaudin had a 10.26 ERA and 12 SO's in 16 innings. Guzman had a 7.30 ERA and 13 SO's in 12 innings. Samardzija had a 7.31 ERA and 12 SO's in 16 innings. Easy choice for the first one. I'd keep Gaudin just because of his experience.
