"Stuff-wise, everything was just working well," Burnes told MiLB.com. "As of last week, I've been trying to work on command on offspeed pitches better and commanding the fastball in the zone. I had a good gameplan with [Jacob Nottingham] behind the plate and just went out there and executed the pitches.
"Today, all the pitches were good in the bullpen," he added. "I've been really working hard on the changeup lately. I have a great pitching coach in Chris Hook, and he gave me a couple of pointers last week and it's really helped me. The changeup was one of the better out pitches tonight."
Burnes, Milwaukee's fourth-round Draft pick in 2016, has been sharp in his three starts for the Shuckers, posting a 1.08 ERA, a 0.60 WHIP and a 19-to-4 strikeout-to-walk ratio in 16 2/3 innings. Prior to that, he had gone 5-0 with a Carolina League-leading 1.05 ERA and 0.88 WHIP in 10 starts for Class A Advanced Carolina.
Overall, Burnes has pitched to a 1.06 ERA in 76 2/3 innings (13 starts) between the two levels. He also owns a stellar 0.82 WHIP and .166 opponents' average, with 75 strikeouts and 20 walks.
