Williams already has an average-to-plus changeup to go with a fastball capable of hitting 95 mph. That alone gives Williams, Milwaukee's second-round pick, a good chance of eventually landing in a major league rotation. Add the fact that the 6-foot-3 righty has room to bulk up and continues to improve his breaking pitches and it's looking like the 22-year-old can travel quickly up the organizational ladder. The question will be if he can overcome his control, which has been shaky at best in his professional career. Williams walked more than four batters per nine innings at both Low-A and High-A, and while he has been nasty enough to get away with it thus far, the upper levels of professional ball won't be so kind. In order to continue his development as a starter, Williams needs to show signs of improving his control in 2017.

Williams spent his first season in the minors in 2015, playing for Low-A Wisconsin. He's only 21-years old, but already has three full seasons in the Brewers' organization and is one of their top prospects on the rise. Despite a 3-9 record, Williams posted a 3.44 ERA and 1.25 WHIP on the mound in the 2015 season after coming off a forearm strain that kept him out until late May. Looking ahead to the 2016 season, Williams will continue to climb through the minors but it looks unlikely to expect him to make the big league roster in the next year.

Since being taken out of high school in the second round of the 2013 draft, Williams has fooled hitters with 105 strikeouts in 101 innings, thanks mainly to his quality fastball that hovers in the low-to-mid 90s. His ERA slipped from his first season to his second, but he cut his walks in half, and has given up just five home runs as a pro. After spending the last two seasons in rookie ball, he could see his first action at the Low-A level in 2014.

The Brewers lost their first-round pick last season after signing Kyle Lohse, but they still snagged Williams, whom some considered a first-round talent, in the middle of the second round. Williams already throws a fastball in the mid-90s, and he could add more velocity as he matures. He still has some work to do on his curveball and changeup, and will need to cut down his walks, but he threw the ball well in his professional debut, posting a 3.38 ERA and striking out 39 batters over 34.2 innings. Williams will not turn 20 until next offseason, so the Brewers may opt to keep him in the Rookie Leagues for now. However, Williams has the potential to be a top-end starter a few years down the road.
