2019 Fantasy Outlook
Drafted just outside the top 100 last spring, Weaver was one of 2018's bigger disappointments, as he ended the season in a mop-up role. It's probably too early to completely write off the 25-year-old right-hander, who was sent to Arizona as the headliner in the Paul Goldschmidt trade. Weaver's first-pitch strike rate along with his swinging-strike rate were virtually the same as the previous season. However, in 2017 Weaver posted a 28.6% strikeout rate, compared to a 19.9% mark last season, perhaps because the book was out on his shallow repertoire. Whiffs aside, Weaver's control and command slid last season, as he walked more while allowing more homers. He still lacks a quality third pitch (opposing batters slugged .589 against his curveball), and his top two pitches (fastball, changeup) were not as dominant as they needed to be for him to have sustainable success. His upside is limited to a low-innings mid-rotation starter until that pitch mix improves. Read Past Outlooks

Past Fantasy Outlooks
Say what you will about a "soft" schedule for Weaver; he was excellent in 2017. The right-hander posted a 2.05 ERA over his first 11 starts, and while a couple of poor performances at the end of the year inflated his overall numbers, Weaver finished with a 3.17 FIP and 2.93 xFIP over 60.1 innings at the big-league level. He averaged 10.7 K/9 and just 2.5 BB/9 -- he had the 28th-best K-BB percentage among 274 pitchers with at least 60 innings. Weaver did well to keep the ball on the ground (49.4 percent GB%) and limit hard contact, resulting in a .287 xwOBA. He is still primarily a fastball-changeup pitcher, but the changeup is a dominant pitch, and his curveball is coming along. The only real concern with Weaver is his workload. He totaled just 138 innings between the majors and minors last year, his highest total as a professional, after throwing 119.1 combined frames in 2016.
Weaver got his first taste of the majors at the latter end of the 2016 season. He pieced together a few rough outings and ended the year with a 5.70 ERA and 1.60 WHIP that was built over nine games (36.1 innings). Lefties were particularly tough for Weaver and they went 23-for-69 (.377) against the 23-year-old. Fortunately for the club, he showed signs of promise and produced a 27 percent strikeout rate in that time. Weaver has shown he's a capable starter in the minors, as he dominated his 12 starts at Double-A Springfield in 2016. Heading into 2017, the Cardinals may have Weaver compete for a spot at the back of their rotation, or could opt to use him from the bullpen as they did at the end of 2016. However, the most likely course of action will be to send him to Triple-A Memphis, where he's only appeared in one game to this point, to keep developing his breaking pitches until he's deemed MLB-ready.
Weaver appears to be a third pitch away from being a No. 3 starter, thanks to a low-90s fastball and a filthy changeup that will work as an out pitch at the highest level. That combination was enough for him to breeze through the pitcher-friendly Florida State League with a 1.62 ERA, 1.11 WHIP, and 88 strikeouts in 105.1 innings. Those numbers rightfully put him squarely on the radar of dynasty league owners, but most reports suggest his curveball lags way behind the rest of his arsenal. Without that third pitch, there is not much to see here, so Weaver should still be seen as a work in progress. Fortunately he is in a competent organization, and at least two years away from the big leagues, so it is OK that he is not a finished product. He will head to Double-A Springfield in 2016, where it should become fairly obvious if he has improved his breaking ball.
The 27th overall selection out of Florida State in the 2014 amateur draft, Weaver is expected to work his way through the Cardinals' system rather quickly and could be competing for a roster spot as soon as 2016. Weaver was only able to log 9.1 professional innings with the club's rookie and High-A affiliates, getting six starts and striking out 12. Expect Weaver to start 2015 in either Low-A or High-A for the Cardinals, possibly finishing the season in Double-A if he pitches well. Weaver has drawn praise as one of the lowest risk pitchers drafted. Fantasy owners still shouldn't expect anything on the MLB level until 2016, with 2017 being the most likely scenario.
