Runs are hard to come by during the postseason, in part because of the outsized impact of cooler weather and overpowering relief pitching. So far this fall, no pitcher has done a better job of keeping runs off the board than Aaron Ashby. Working in a multi-inning role that recalls a bygone era of bullpen firemen, the 28-year-old lefty has delivered 12 1/3 scoreless innings for the Brewers thus far while playing a central role in both their Division Series win over the Padres and their Championship Series victory over the Dodgers — so much so that he assembled a reasonable NLCS MVP case, though the award went to Jake Bauers instead.

Ashby has pitched in six of Milwaukee’s eight playoff games, coincidentally Games 1, 2, and 4 of both aforementioned series. He’s thrown more innings than any other Brewer this postseason; by comparison, starters Robert Gasser and Logan Henderson have each totaled nine, and Jacob Misiorowski eight. Four of Ashby’s six outings have been hitless, and all but one has lasted at least 1 2/3 innings, a luxury afforded by the October schedule’s extra days off and his own efficiency and stamina.

“The way this guy loves to play, loves to throw every day. He keeps on wanting the ball,” said pitching coordinator Jim Henderson of Ashby in the wake of the NLCS clincher. “He’s trained himself for it. Every single day he plays catch, he gives it a full effort. He doesn’t save bullets. He creates them.”
