A's closer Blake Treinen last pitched at Nationals Park just over a year ago.
On July 7, 2017, Treinen retired all three batters he faced in his last inning of action with the Washington Nationals, before being traded to Oakland.
375 days later, he did the same thing, this time as an All-Star. The NL All-Stars went three up, three down against Treinen in his Midsummer Classic debut.
Along the way, Treinen even received help from his A's teammate and fellow first-time All-Star, second baseman Jed Lowrie.
Thanks to his perfect sixth inning, 30-year-old reliever handed off a 2-1 lead to AL teammate Charlie Morton in the seventh inning. Morton relinquished the lead on a Trevor Story solo homer.
Treinen pitched for the Nationals from 2014-17. Oakland traded Treinen, a 2011 seventh-round draft pick, to Washington as part of a three-team deal in 2013. Fans in D.C. gave him a warm welcome to his former home.
Big cheers for Wilson Ramos, AL All-Star, but also for ex-Nats Felipe Vasquez & Blake Treinen who, since he went to A's, has 1.47 ERA, 37 SV in 75g. Everybody said he'll figure it out, he just needs a change of scenery. Who knew anybody could luv Oakland's scenery THAT much.— Thomas Boswell (@ThomasBoswellWP) July 18, 2018
