2019 Fantasy Outlook
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. Read Past Outlooks

August 20, 2019
Williams (5-6) took the loss Monday, surrendering eight runs (six earned) on six hits and three walks over only two innings while striking out one as the Pirates were routed 13-0 by the Nationals.
Three of the six hits off Williams left the yard, but given that the Washington offense has been averaging better than 12 runs a game since last Wednesday, there may not have been much he could have done to avoid the drubbing. The right-hander now carries a 5.65 ERA and 81:32 K:BB through 106.2 innings, and he'll look to turn things around in his next start Saturday, at home against the Reds.

Stat Review
How does Trevor Williams compare to other starting pitchers?
This section compares his stats with all starting pitcher seasons from the previous three seasons (minimum 120 innings)*. The bar represents the player's percentile rank. For example, if the bar is halfway across, then the player falls into the 50th percentile for that stat and it would be considered average.

* Exit Velocity, Barrels/BBE %, Balls Hit 95+ MPH %, and Spin Rate are benchmarked against this season's data (min 70 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.
  • K/BB
    Strikeout to walk ratio.
  • K/9
    Average strikeouts per nine innings.

Past Fantasy Outlooks
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.
