Well, the Cubs did a lot to shore up their bullpen via trade I guess. Obviously Chapman is the big fish but Mike Montgomery is a quality LHP that is cheap for a few more years and should help them. They added vet Joe Smith from LAA at the deadline. Not quite sure why they added him but I think mostly for depth. He has traditionally been really tough on righties but not as much of a split this year as usual. I also suspect it is because they will stretch Trevor Cahill out to the the long man/emergency 6th starter since they no longer have Adam Warren.
Believe it or not Joe Nathan has looked pretty good in limited action since he came back as well. His velocity is where it should be and he is a savvy vet. Carl Edwards, Jr. (aka CJ Edwards) has looked awesome out of the pen though. I am excited about what I am seeing out of him. The average velocity of his 4 seam fastball is sitting at 95.7 right now and he's throwing strikes and mowing people down. Pretty electric stuff.
