Cubs relievers had a 3.46 ERA coming into today Do you believe that ERA accurately reflects their performance, or has there been some unsustainable luck involved over a small sample size? Dillon Maples currently has an ERA of 2.00, but walks more than 1 batter per inning. Dan Winkler is at 1.43, but has also walked 1 batter per inning. It is only a matter of time before the walks come back to burn them, and the bullpen as a whole. Sure, but then you have Chafin and Brothers on the flip side of that coin: strong peripherals and a crappy ERA. Chafin's the primary setup man too, so you feel those unlucky runs more than you benefit from Maples escaping damage while we're already down 6. We need to figure out which of Tepera/Adam/whomever from AAA is the second RH setup guy, but otherwise I feel quite good about the pen. Kimbrel's been incredible, Workman started a little slow but has been good overall, Chafin's been great but unlucky, etc. I think early in the year people are even more prone to freakouts than normal, so a legitimately bad weekend for the pen has people on the ledge.
