After a very fast start, Mitchell Parker has struggled since the end of April. He had a 1.39 ERA through his first five starts, but now that is up to 4.44. Parker has been better his last couple starts, but he still has one massive issue. He is getting shelled in first innings.
His numbers in the first frame are ugly. For the season Parker has an ERA of 10.38 in the first inning. The fifth inning is the only other frame where he has an ERA over 4. It has become increasingly noticeable in his last three starts.
