How acquired: Trade with A’s (February 12, 2016)

Profile: Acquired from the Oakland A’s in February of 2016 along with catcher Jacob Nottingham in a trade that sent outfielder Khris Davis to the A’s, Derby was originally drafted by Oakland in the sixth round of the 2015 draft out of San Diego State University. After starting out as a reliever with the Aztecs, Derby moved into the starting rotation, where he became their Friday starter. He saw action with two of the A’s rookie league affiliates after signing in 2015 before being traded to Milwaukee in the offseason. The Brewers aggressively promoted Derby to High-A Brevard County in 2016, skipping him over Low-A Wisconsin. A bit on the small side and with slightly odd mechanics, Derby’s long-term future may lie in the bullpen where his fastball has clocked in as high as 97 mph in the past. On the flip side, Derby has both a slider and a changeup that are better than average pitches for him and is a good athlete who showed the ability to handle a heavy workload last season, so the Brewers may opt to continue to look at him as a starter for the time being.

2015: After signing with Oakland following the draft, Derby made a pair of starts in the Arizona League before quickly receiving a bump to Vermont in the New York-Penn League. He made 12 more appearances there, starting eight games, and was dominant, going 1-0 with a 0.78 earned run average, striking out 45 over 34.2 innings while holding opposing hitters to a .161 batting average.

2016: Traded to Milwaukee in February, Derby impressed enough during spring training to jump past Low-A Wisconsin and opened the 2016 season with High-A Brevard County. He started 25 of the 26 games he saw action in, going 6-13 with a 5.59 earned run average.

2017: After struggling some in his first season in the Milwaukee system, Derby bounced back with a terrific 2017 campaign. He split time between Double-A Biloxi and Triple-A Colorado Springs, starting 14 of the 30 games he worked in. He finished the year with a record of 7-1 to go along with a 3.26 earned run average between the two levels combined.
