2021 Fantasy Outlook
Fiers' most notable impact on the 2020 season came over the offseason, when he outed his former Astros teammates for cheating. On the field, he was the same decent back-end starter that he's been for several years. His ERA jumped from 3.90 to 4.58, but his FIP barely moved, falling from 4.97 to 4.94. His already low strikeout rate fell by more than two percentage points for the third straight year, however, dropping from 16.7% to 14.4%. He also recorded his lowest groundball rate (35.0%) since 2014. Missing very few bats while generating very few grounders isn't exactly a recipe for success, though Fiers has been able to succeed with it, thanks in part to good control, as he posted a 6.2 BB% last year. That's kept him in a stable job into his mid-30s, but his effectiveness could collapse if he finds the lower bound for the number of strikeouts and grounders needed to remain a viable big-league arm.

Fiers (elbow) suffered a setback during his rehab assignment and is unlikely to return this season, Martin Gallegos of MLB.com reports.
ANALYSIS
Fiers appeared in three games at Triple-A Las Vegas over the past couple weeks, but he's been unable to reach his desired velocity and may make a visit to Dr. James Andrews, per Shayna Rubin of The San Jose Mercury News. The 36-year-old may not be available even if the A's manage a sustained playoff run.

* Exit Velocity, Barrels/BBE %, Balls Hit 95+ MPH %, and Spin Rate are benchmarked against 2019 data (min 120 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

Oakland was the perfect place for Fiers to land. The A's needed a better version of Marco Estrada, and Fiers needed the spacious park and foul ground for his style of pitching. They indeed fit one another well as Fiers had a productive season with 15 wins and a decent ERA considering the run environment of 2019 along with a solid WHIP. He had a 12-game stretch (which began with his no-hitter against Cincinnati) in which he went 8-0 with a 2.09 ERA and 0.93 WHIP, holding batters to a .187 average. He went 5-1 the rest of the way as Oakland seemingly could not lose, but did so with a 4.37 ERA (5.54 FIP) and 1.33 WHIP. The lack of consistent swing-and-miss stuff and the flyball approach leave him fraught with risk. Last year is what happens when it all works out well, and 2017 is what happens when it does not. There is more to dislike in his numbers for 2020 than there is to like.
Fiers was dealt from Detroit to Oakland in early August and went on a great run (5-1, 2.90 ERA, 0.99 WHIP in 49.2 innings) to help the A's secure a wild-card spot. He slipped up in a relief appearance in his final outing of the regular season, but in the end, Fiers had some of the best numbers of his career. His 5.2% walk rate was a career low and a big improvement on 2017 (9.2%), helping lead to his second-lowest WHIP. However, he needed quite a bit of good fortune to get there (84.2 LOB%, .269 BABIP). He lost some of his strikeout punch (19.5%) and home runs remained a big issue (1.67 HR/9), even as he pitched in two bottom-10 parks for homers. Indeed his FIP (4.75) was well over a run higher than his ERA (3.56), and was a bottom-five mark among qualified starters. After returning to the A's, Fiers will continue to toe the rubber every fifth day, but if he gives back even some of the control gains, things could get ugly.
His career 8.5 K/9 might suggest otherwise, but Fiers relies heavily on deception ahead of power: his fastball sits in the low-90s and is aided by an unusual delivery and arm angle which work to hide his release point. Unfortunately, Fiers hasn't been able to deceive opposing hitters as much in recent years, as he's allowed 1.6 HR/9 over the last two seasons -- a disturbing trend in one of baseball's most prolific homer eras. The right-hander also experienced an uptick in walks last season, with his BB/9 rate leaping from 2.2 BB/9 to 3.6. The Astros, with a plethora of capable starting options, declined to tender Fiers a contract for 2018. The 32-year-old will get a chance to start again after signing with the Tigers, and his diverse arsenal can still guide him through occasional periods of success, but chasing Fiers' good starts will likely prove detrimental.
Fiers' first full season in Houston was a mixed bag, as he showed skills growth with an improved walk rate (2.2 BB/9) and the highest groundball rate of his big league career (42.2 percent), but struggled to keep the ball in the yard with the highest home-run rate (1.39 HR/9) he's had in any campaign as a pro. Little has changed with Fiers' arsenal, but his high-80s fastball, which is only effective when he's painting the corners of the strike zone, was hammered by opposing hitters to the tune of a .343 batting average against and a .653 slugging percentage against. By comparison, the opposition hit .246 with a .453 slugging percentage against Fiers' fastball in 2015, so he's shown an ability to get by without good velocity in the past. He may prove capable of shaving a half-run from his 2016 ERA, but expecting more than that level of improvement without a significant change to his pitch mix is a stretch.
Acquired by the Astros with Carlos Gomez at the trade deadline, Fiers pitched well for his new club after a rough start to the season with Milwaukee. The 30-year-old right-hander went beyond the sixth inning just once in his first 12 starts, as a lack of velocity (89.4 mph) often forced him to nibble around the strike zone, which often led to high pitch counts. Despite his early struggles, Fiers logged a career-high 180.1 innings in 31 appearances (30 starts) between the Astros and Brewers, going 7-10 with a 3.69 ERA and 1.25 WHIP. He did allow 24 home runs on the season for a terrible 1.2 HR/9, but he still struck out nearly a batter per inning and owned a 3.32 ERA and 1.06 WHIP after arriving in Houston. Fiers is projected as the Astros' fourth starter to open 2016.
A trying 2013 season landed Fiers at Triple-A Nashville to open the 2014 season, and he made all of four appearances for the Brewers before August. However, that was due to the depth of the rotation at the big league level, as Fiers was brilliant with Nashville. He sustained that success when he was called up to Milwaukee, and did not give up more than three earned runs in any of his 10 major league starts. Fiers does not have a big fastball, but he has struck out over a batter per inning and owns a 1.18 WHIP over his big league career. Thanks to his impressive 2014 campaign, consider Fiers the front-runner for the Brewers’ fifth starter job.
Fiers burst onto the scene in 2012, posting a 1.80 ERA over his first 13 games (12 starts), but he faltered late that year, and his struggles carried over to 2013. Fiers won the fifth starter job during spring training, but was removed from the rotation after just one appearance, sent to the minors, and briefly recalled before being sent down again in June. When it was all said and done, Fiers ended up giving up 18 earned runs over 22.1 innings with the Brewers and saw his season come to an early end after breaking his arm in June. Fiers was effective at first thanks to a deceptive delivery, but he does not possess a formidable arsenal, and it’s highly unlikely he will regain the form that led to his initial success in 2012.
Fiers was the Brewers' Minor League Pitcher of the Year in 2011, but few expected him to throw the ball as well as he did in his first stint in the majors. Fiers tired late in the season and finished with a 3.74 ERA, but he also posted a 135:36 K:BB ratio over 127.2 innings and held the opposition to two earned runs or fewer in 12 of his 22 starts. Although he pitched well in his first exposure to big league hitters, he will need to earn his place in the rotation by pitching well again in spring training, and it is unclear if the Brewers would consider him for long relief if he fails to lock down a starting gig in Arizona this spring.
Fiers started last season at Double-A Huntsville and ended in Milwaukee. He doesn't throw hard, but has a funky delivery that helped him strikeout more than a batter per inning in 2011. Fiers has an outside chance at a rotation spot in 2012, but could also stick as a long reliever in the bullpen thanks to a four-pitch arsenal and low walk rate. In many ways, his role and upside could parallel that of Arizona's Josh Collmenter.
