In June, Merrill Kelly had three of the four wins that went to Arizona starters, going 3-2 with a 3.60 ERA. The rest of the rotation combined for a 1-10 record with a 5.18 ERA. Some of that is a bit unfortunate. Zach Davies had a great month, with a 2.56 ERA and three quality starts in his five outings, but was winless in May. However, the fifth spot was a well-documented disaster, and Zac Gallen and Madison Bumgarner both fell back to Earth. Each of their regression was somewhat expected, their FIPs having come into the month significantly higher than their ERAs.
