2024 Fantasy Outlook
After battling elbow soreness throughout camp, Stephenson opened last season on the injured list. He was activated in mid-April and struggled to a 5.14 ERA and 1.43 WHIP over 14 innings with Pittsburgh. An early-season trade to Tampa Bay accompanied a pitch mix change for the right-hander, as Stephenson implemented a cutter that was devastating to opposing hitters. In fact, it was one of the best pitches in all of baseball, generating a 59.9% whiff rate that was second-highest in the league among all pitch types. It helped the 30-year-old generate a career-best 38.8% strikeout rate, 24.0% swinging strike percentage and 30.4 K-BB% that was second-best among qualified relievers. Stephenson's breakout season and career-best ratios -- including a 0.88 WHIP -- should land him in the closer role with the Angels after he signed a three-year deal in January. Read Past Outlooks

ANALYSIS
Stephenson was one of the Angels' biggest signings in the offseason, but he won't appear in a game for the team in the first season of his three-year contract. He opened the season on the injured list while recovering from right shoulder inflammation, then suffered ligament damage to his elbow in mid-April while pitching in a minor-league rehab game. Though Stephenson had a brace inserted to help stabilize his elbow and hopefully accelerate his recovery timeline, he's still expected to 12-to-18 months to fully heal.

Stephenson was excellent down the stretch last season after being claimed off waivers by the Pirates, holding a 3.38 ERA and 18:1 K:BB over 13.1 innings. The team had the reliever go slider-heavy, which makes sense because he's always gotten terrific results with the pitch, unlike with his fastball. The former first-round pick has the potential to finally break out if he continues to stick with his best pitch and throws enough strikes. He could even be next-in-line for saves if David Bednar gets hurt or traded, although Stephenson would be a trade candidate himself as an impending free agent. The 30-year-old has dealt with some arm soreness in spring training, although indications are that it could be minor.
While the dream of Stephenson blossoming from top prospect into ace starter died long ago, the right-hander seemed to be finding his niche in relief in 2019. In fact, he ranked third among all qualified relievers in swinging-strike rate that year (18.9%), behind only Josh Hader and Nick Anderson. This past year saw Stephenson battle a wrist injury in summer camp, allow five homers in his first five appearances and earn just a single hold. Homers aside, Stephenson was good, posting a 23.3 K-BB% and ranking among the elite in terms of expected outcomes. Regardless the Reds sent their 2011 first-round pick packing to Colorado in November. Coors Field is a terrible place to pitch, but there is opportunity for advancement in the Rockies' bullpen and saves are not out of the question in 2021.
Stephenson might not have been done as a big-league pitcher after 2018, but he was extremely crispy. The Reds transitioned him to the bullpen, and while it's not exactly a novel idea to see a struggling young starter thrive as a reliever, the degree of Stephenson's transformation was startling. Not only did he post good overall numbers, but he dominated over the second half. From the All-Star break to the end of the season, covering 26 innings, Stephenson posted a 1.38 ERA, 0.73 WHIP and 28:7 K:BB. Pitching coach Derek Johnson was able to get Stephenson to generate more velocity and spin on his slider and four-seamer, and encouraged him to use that wipeout slider even more than he had in 2018, throwing it a whopping 57.7% of the time. It was a positive change -- opposing hitters hit a paltry .122 and slugged .245 against that slider, whiffing 52.2% of the time.
Last year we expressed concern about the extremely negative results Stephenson had with his fastball (17.1 runs below average per Fangraphs). The Reds and Stephenson noticed those results as well, and adjusted by having him throw it less frequently, down to 36.2% from 54.3% in 2017. He replaced his fastball use with more sliders, his best pitch. Unfortunately he still had the same negative results. In 11.2 innings he managed to be -6.0 runs below average with that fastball. Command and control are both issues for him. Stephenson can't reliably throw his slider for strikes, and he can't locate his fastball in the right spot in the strike zone. Occasionally Stephenson has had good stretches at Triple-A Louisville, but even those were marred by the occasional high-walk game. New pitching coach Derrick Johnson will have his hands full to see if he can turn Stephenson around.
Is Stephenson's strong finish to the 2017 season (2.50 ERA, 1.27 WHIP over 50.1 innings) real or a mirage? The 2011 first-round pick was routinely getting cuffed around at the big-league level prior to that end-run, frequently falling behind in the count and then getting punished after putting runners on. He stopped throwing his curveball, and started using his slider and changeup more often, bringing positive results. His fastball remains a big problem -- it was a whopping 17.1 runs below league average last year, albeit not quite as bad later in the season. And therein lies a problem -- it's not as if Stephenson can scrap his fastball. Maybe he can change his grip, or find a better way to improve his location, but at the end of the day, he's going to need a decent fastball to get by. The Reds owe it to themselves to see if he can do that, but you owe it to yourself to invest no more than an endgame pick to find out if he'll be successful.
Stephenson is one of the Reds' most highly-touted prospects, but the window for him to make it as a starting pitcher is closing. He can miss bats with a three pitch-mix -- highlighted by a fastball that routinely sits in the mid- to upper-90s -- but he struggles to locate with consistency. Stephenson made eight starts for the big club in 2016, seeing mixed results. His tenure with Cincinnati started well enough, as he went 2-0 with a 3.00 ERA and 1.08 WHIP in his first two starts in the big leagues. He was sent back to Triple-A afterward and stayed there until September, and he was far less successful upon his return. In six September starts, he only got through five innings once and amassed a 7.56 ERA and 1.88 WHIP thanks to a 5.4 BB/9 and 2.5 HR/9. Stephenson is still an intriguing arm, but if he doesn't take that next step in his development, we could see him in the Cincinnati bullpen before the end of the year.
Stephenson's start to the 2015 season at Double-A Pensacola raised a lot of concerns in Reds-land. It began in spring training, when a sore shoulder prevented him from seeing any meaningful action against big league hitters. That spilled over to the regular season, where he really struggled to throw strikes despite repeating the level. However, he made an adjustment in late May and with that came a big spike in his strikeout rate along with a semblance of control. He earned a promotion to Triple-A Louisville at the beginning of July, but missed out on a September callup to the big leagues due to a forearm strain that put him on the DL. He'll probably start 2016 back at Louisville, if for no other reason than to slow down his service time, but expect him to be up with the Reds by midseason.
Stephenson hit the Double-A wall in 2014, and the wall hit right back, giving him his worst professional season. Stephenson's command, in part defined by how he uses his stuff, was his big problem. His walk rate skyrocketed to 12.3%, and all too often he would fall behind hitters and resort to challenging them with his 97 mph fastball high in the strike zone. Shockingly enough, Double-A hitters were better equipped to handle it when they knew it was coming. The Reds seem confident that he'll adjust accordingly with another year of experience. Keep in mind that he hit Double-A as a 21-year old, and remain optimistic about him despite the down year.
After a couple of rocky starts in April, Stephenson dominated both Low-A and High-A last season before landing in Double-A Pensacola to finish the year. The Reds took a slow approach to developing him after making him their first-round pick out of high school in the 2011 draft, and it is starting to pay dividends, as most prospect lists out there have him leapfrogging Billy Hamilton as the Reds' top prospect. His fastball has been clocked as fast as 101 mph (albeit on scoreboard radars, which are notoriously fast) and he typically works in the 96-98 mph range. A hamstring injury limited his innings last year, which isn't all bad given that he was just 20 years old. It wouldn't be a surprise to see him spend most of the year in Double-A, but a 2015 major league debut seems likely.
The Reds' first-round pick in 2011, Stephenson made his professional debut last season and impressed at two levels, striking out a combined 72 batters in 65 innings. The Reds will probably take a deliberate approach with Stephenson, though they're faced with the conundrum of going from an extreme pitcher's park at Low-A Dayton to a hitter's park at High-A Bakersfield. The Reds avoided that with Daniel Corcino, skipping him right from Dayton to Double-A Pensacola, so we'll see if they take that approach here as well.
Stephenson was the Reds' first-round pick in the 2011 June draft. A high school pitcher from California, Stephenson signed late and will make his professional debut in 2012. He's a big right-hander who throws in the mid-90s. The Reds tend to move their high school draftees along slowly, so Stephenson may not even make it to Low-A Dayton this season, barring a stretch of dominance in rookie ball.

Market picking back up

January 18, 2024
Stephenson is drawing interest from the Mets, Dodgers and Phillies, Jon Morosi of MLB Network reports.
ANALYSIS
The reliever market looks likely to pick up in the coming days, as reports also emerged that the Astros are in pursuit of Josh Hader. While not the same caliber of reliever as Hader, Stephenson proved capable of excelling in a high-leverage role in 2023 by piling up a career-best 15 holds while maintaining a 3.10 ERA and 0.88 WHIP across 52.1 frames. Wherever he lands, he's likely to fill a setup role.
