player. 21. Karns has settled into the Rays rotation and put together a solid May going 2-1 with a 2.38 ERA. Today, he makes his third start of the season against Baltimore going 0-1 with a 5.06 ERA in his first two outings. He did look good in Baltimore when he faced them May 3 allowing two hits in five shutout innings. He doesn’t typically go extremely deep into the game, and he does have upside, but Baltimore knocked him around in his first start of the season scoring six runs in 5.2 innings which is reason for caution in deploying Karns today.. Tampa Bay Rays. @ Orioles. Nathan Karns. 21
