2019 Fantasy Outlook
Treinen dug in as the Athletics' closer in 2018 and ended up as one of the most valuable relievers in fantasy. His 18.0 swinging-strike percentage ranked third among qualified relievers. He molded a cutter to conquer lefty batters, completing the missing piece of his skill set. Still, it's impossible to bank on him returning as much earned value in 2019; nine wins enhanced his 2018 value, he had an 85.9 left-on-base percentage and a .230 opponents BABIP. The latter two can fluctuate greatly given relievers' small sample sizes. However, even if he gives back some of that, Treinen should find a soft landing. He has a standout sinker, his control has improved greatly and he posted the fourth-lowest barrels-per-PA rate in the majors (min. 150 batted-ball events). After a dominant season in which he built up a long leash in the role, Treinen has a case to be the first closer off the board in 2019 drafts. Read Past Outlooks

Treinen (back) will not pitch in any postseason games, Shayna Rubin of The San Jose Mercury News reports.
ANALYSIS
The issue is serious enough that the A's can already rule Treinen out for games that could take place weeks from now. However, given his struggles prior to the injury (4.91 ERA, 1.62 WHIP in 58.2 innings), this seems like a common sense move even if he were medically cleared.

Stat Review
How does Blake Treinen compare to other relievers?
This section compares his stats with all relief pitcher seasons from the previous three seasons (minimum 30 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 2019 data (min 30 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

  • Spin Rate
    Spin Rate is the rate of spin on a baseball after it is released. It is measured in revolutions per minute (rpm).
  • Balls Hit 95+ MPH

Past Fantasy Outlooks
2018
2017
2016
2015
Treinen was the Nationals' first choice to close, but he absorbed a 7.11 ERA and a 2.53 WHIP through his first eight games and then spent several months in irrelevant fantasy roles until Washington shipped him to the Athletics. For his new club, he rattled off a 2.13 ERA with 42 strikeouts in 38 innings while converting 13 of 16 save chances. At season's end, he'd increased his swinging-strike rate from 10.5 percent in 2016 to 13.1 percent His sinker, emerging plus-slider and serviceable four-seam fastball gained velocity befitting a stopper. The right-hander should be ready for spring training following October surgery to remove a cyst from his middle pitching finger. It's safe to wonder whether that was hindering his grip last season, considering his elite groundball rate dipped to a still awesome 58.4 percent.
Treinen developed into a true late-inning arm in 2016 after an up-and-down performance in his first two years in the league, leading the Nationals' bullpen with 67 innings while posting a 2.28 ERA. His main step forward was that he was simply adequate against left-handers, yielding a league-average .737 OPS to lefties in 2016 compared to an awful .934 in 2015. Treinen is a classic sinker-slider type of pitcher, with both pitches coming in extremely hard. He tops out at around 97 mph, but that hasn't translated into elite strikeout numbers yet (he posted an above-average 24 percent strikeout rate last season). Instead, he lives on the ground, having improved his groundball rate in every season of his MLB career. His 65.9 percent mark was second to only Zach Britton among pitchers with at least 60 innings in 2016. Treinen is likely to again fill a setup role in 2017 alongside Shawn Kelley and Sammy Solis.
Expected to step into Tyler Clippard's set-up role after the veteran right-hander was traded in the offseason, Treinen struggled to harness his nasty 96 mph sinker in his first full season as a reliever, bouncing between the majors and Triple-A and posting fairly mediocre numbers overall with the Nationals. His main difficulty came against left-handed hitters, who raked him for a .336/.425/.509 slash line and 21:17 K:BB ratio, and until he can find a way to counter them, he'll have trouble providing consistent help out of the bullpen. The Nationals currently have Jonathan Papelbon and Drew Storen filling late-inning roles, although given the volatile way each of their seasons ended, either or both could be in other uniforms before GM Mike Rizzo is done this winter. Depending on what happens around him, Treinen could head into 2016 as staff filler with upside or as someone once again counted on to fill a role he hasn't proven he's ready for yet.
Treinen made a strong impression on the Nationals' coaching staff last spring when he fired a sinking fastball that was regularly clocked in the 95-98 mph range when used as a reliever. Moved back into the rotation at Triple-A and then used as a swingman during his various brief stints in the majors, the 26-year-old did enough to put himself in contention for a regular spot on the Nationals' staff in 2015, posting a superb 0.34 HR/9 rate in 131.1 innings across both levels. Given the organization's rotation depth and the way his sinker plays up in relief, he's likely ticketed for the bullpen long-term. If he sharpens his slider and changeup, he could yet prove he deserves a shot at the rotation.
