MILWAUKEE — Kyle Harrison told himself to treat Tuesday night’s game against the San Francisco Giants like any other start. Blot out the past. Bottle up the emotions. Tunnel his vision along with his pitches.All of those thoughts got wrestled to the ground when the first batter of the game stepped into the box. It was Casey Schmitt, Harrison’s teammate at every minor league stop, beginning at Low-A San Jose when he was a 19-year-old left-hander still figuring out how to do his own laundry.If Schmitt’s presence conjured memories of Harrison’s beginnings in the Giants organization, then the second batter of the game represented its end. It was Rafael Devers, the three-time All-Star slugger whom the Giants acquired from the Boston Red Sox almost exactly a year ago for a four-player package that included Harrison.“You use that as fuel,” said Harrison, who was in the middle of his pre-start routine in the Dodger Stadium bullpen on June 12 of last year when he got tapped on the shoulder. “It sucked getting traded that day. I didn’t know what to expect and then I got sent to Triple-A (by the Red Sox) that same day. My head was spinning. But then you bring it back to, ‘I’ve just got to worry about baseball and get better each and every day and keep grinding, because one day it’ll work.'”Everything is working for Harrison this year following another trade to Milwaukee in February. And everything was working against his original team Tuesday night.Harrison authored perhaps his most dominant start in what’s been an All-Star first half. He struck out 10 of the first 16 batters he faced, yielded only a solo home run to Willy Adames before departing in the sixth inning and matched his career high with 12 strikeouts in Milwaukee’s 8-3 victory over the Giants at American Family Field.
