2020 Fantasy Outlook
Williams showed flashes of brilliance in 2018, but failed to make much of a fantasy impact in 2019, finishing the year with a 5.38 ERA and 1.41 WHIP around injuries. His struggles can be attributed in part to the juiced ball (27 home runs allowed, up from 15 in 2018). The right-hander found success in 2018 by limiting the amount of hard hits allowed, and even with the homer issues last year he was still better than average in terms of average exit velocity and hard-hit rate. His fastball velocity ticked up to 91.3 mph in 2019, which helped bring his swinging-strike rate up to 10.4%. With the MLB run environment impossible to predict, Williams is merely on the margins of fantasy relevance; his windows of efficiency proved unsustainable in a juiced-ball year. Williams will look to right the ship and his home park should help in that regard, but he's barely even in the glob until further notice. Read Past Outlooks

September 13, 2020
Williams (1-7) took the loss Saturday as the Pirates were downed 7-4 by the Royals, surrendering six runs on 10 hits and three walks over five innings. He struck out four.
ANALYSIS
Two of the 10 hits left the yard, and Williams struggled in almost every frame. The right-hander threw 65 of 101 pitches for strikes as he lost his fourth straight decision. Williams will carry a 6.35 ERA, 1.63 WHIP and 42:18 K:BB through 45.1 innings into his next outing Thursday, at home against the Cardinals.

Williams provided the most confounding success story of the 2018 season. During a nine-start run from July to early September (54.2 innings), Williams posted an incredible 0.66 ERA and 1.06 WHIP. He achieved those marks despite just a 34:17 K:BB over that stretch. It was a microcosm of his season as a whole; while Williams obviously wasn't that successful over the course of the full year, he still finished with great ratios despite an utter lack of dominance. Williams barely cracked 90 mph on average with his fastball, which he threw 70% of the time, and induced swinging strikes at a career-low 7.9% clip. So how on Earth did he do it? And is it sustainable? In short: by inducing a lot of manageable, playable contact, and no. His opponents' 85.6 mph average exit velocity was among the lowest in baseball, but without the other numbers in the underlying profile, there's simply not much to get excited about. Don't pay for last year's numbers.
Williams settled in as a back-end starter for the Pirates last season, providing an innings-eating option every fifth day. For those who were careful to use him as a home streamer, Williams returned plenty of value with good ratios at PNC Park (3.45 ERA, 1.17 WHIP) despite a very limited ability to induce whiffs. Away from Pittsburgh, his ERA was more than a run-and-a-half higher (4.96), but it's interesting to note that his ability to keep the ball in the park did not change much in more hitter-friendly parks. Looking forward, Williams should have an inside track to begin the year back in the Bucs' rotation. In order to stay there and to remain effective, he'll need to improve his changeup, as opposing hitters hit .328 with a .547 slugging percentage against that offering last season, and ideally, improve his walk rate as well, as there isn't much in his current arsenal that suggests a spike in strikeouts is on the horizon barring the addition of a new pitch or an increase in velocity.
Williams' postgame embrace with his dad following his first appearance (and win) was one of the more emotional scenes in baseball last year. The 25-year-old started in 19 of his 20 Triple-A games, going 9-6 with a 2.53 ERA and 1.20 WHIP in 110.1 innings. A 74:30 K:BB serves as a reminder he'll probably never be a big strikeout guy. For the Pirates, Williams fell off after his debut. He gave up 11 earned runs, 16 hits and four walks in 9.2 innings, striking out four. Based off his strong Triple-A showing and the fact he served as informal trade compensation when Miami hired away pitching guru Jim Benedict from Pittsburgh, Williams will likely receive ample opportunities to prove his worth as a serviceable innings-eater for the Bucs.
As a sinkerballer with the body to eat innings, there is more pitchability than stuff in Williams’ profile, but he still has a good enough repertoire to succeed at the back of a big league rotation. The 23-year-old righty has a solid four-pitch mix but has yet to showcase above average command in the upper levels of the minors. Williams posted a 4.00 ERA, 1.38 WHIP, and a 88:36 K:BB over 117 innings at Double-A Jacksonville before earning a late-season promotion to Triple-A New Orleans where he made three solid starts. He was traded to the Pirates in the offseason -- a move that might lessen his chances of joining a big league rotation this summer, given the disparity of pitching depth between the two organizations. Look for the Pirates to use Williams as rotation depth in the second half of 2016.
A second-round selection in 2013, Williams totaled 144 innings pitched across two minor league levels, reaching Double-A for the final three starts of the season. It was another positive step for Williams, who does not come as highly regarded as many of the other prospect arms in the Marlins' system, as he continues put the results on tape. The right hander went 8-7 with a 3.13 ERA and 1.35 WHIP over 26 starts during the 2014 season, his first full season of professional ball. Though Williams is fairly hittable and has posted mediocre strikeout totals so far, he shows solid command and consistent effort. Williams should slot into the rotation at Double-A Jacksonville out of spring training as he continues to progress up the ladder.
