Blake Treinen returns to Nationals Park as first-time All-Star
A year and a day after the Washington Nationals shipped closer Blake Treinen to the Oakland Athletics along with two minor leaguers in exchange for Sean Doolittle and Ryan Madson, Treinen returned to Nationals Park with an A’s insignia on his hat and a No. 1 inside a black star on his left shoulder. Treinen departed Washington on July 16, 2017, with a 5.73 ERA. On Tuesday, he returned to the District as an All-Star, sporting a 0.94 ERA with 24 saves for Oakland.
