The Rays took a 9-3 beating at the hands of the Mariners on Monday, when McKay yielded seven runs (three earned) on three hits and three walks over two innings of work. McKay has regularly shuttled between the majors and minors in what has been a promising but frustrating debut campaign for the touted 23-year-old. While McKay has pitched to a weak 5.55 ERA in 35 2/3 innings, he has logged 10.35 K/9 against 3.03 BB/9 at the same time.
Milner, whom the Rays acquired from the Phillies in July 2018, threw just 7 1/3 major league innings last year and hasn’t pitched in the bigs yet this season. The 28-year-old has, however, thrived at Durham, where he has put up a 3.32 ERA/3.09 FIP and 13.11 K/9 against 2.05 BB/9 across 57 frames.
