MLB Debut Date: 9/9/2016
|September 9, in a 7-6 12-inning loss to the San Francisco Giants. He was the 11th of 12 pitchers on the night (the Diamondbacks set a franchise record with 12 pitchers and 26 players in the game, a group effort prompted partly by the return of pitcher Rubby de la Rosa, who started in his first outing off of the 60-day DL and went two innings). Koch tossed one shutout inning, walking two without giving up a hit. Starting the 11th inning, he walked the first two batters he faced, Denard Span and Angel Pagan. Span then advanced to third on Buster Posey’s fly out to right field. Brandon Crawford reached base on a fielder’s choice when first baseman Paul Goldschmidt relayed the ball to catcher Welington Castillo to nail Span at home, after which Hunter Pence grounded out softly in front of the plate, and Castillo’s throw to Goldschmidt got Pence for the third out.|
|The native of Storm Lake, Iowa, moved from starting into relief for the Mets in 2015, but the Diamondbacks have moved him back to starting, at least for now. With a fastball in the low-to-middle 90s as well as a slider, changeup and curveball, all of which he can throw for strikes, he combined to go 5-8 with a 3.48 ERA in 95.2 innings between two Double-A stops in 2015, at Binghamton (Mets) and Mobile, striking out 61 while walking just 19. He earned Florida State League All-Star laurels in 2014 at St. Lucie (High A) when he won 10 games, going 10-4 with a 4.64 ERA.|
