Oakland A’s closer Blake Treinen was named the American League Relief Pitcher of the Month on Saturday, the team announced. In 14 appearances in May he posted an 0.59 ERA and converted all 10 of his save chances.
Treinen, May 2018: 0.59 ERA, 15u2153 ip, 19 Ks, 5 BB, 0 HR, 8 hits, 1.63 FIP
The only run Treinen allowed last month came in Boston, while protecting a three-run lead. The leadoff man struck out but reached on a wild pitch, then came around on a double and a groundout. Otherwise, the right-hander was untouchable, with a 32.
