Joe Kelly

A shoulder injury delayed Kelly's 2021 debut until early May. He went on to record the best season of his career, setting personals bests in strikeout and walk rates. A fortunate .227 BABIP played a part as well. Kelly's season ended prematurely in the playoffs with a sore biceps. Kelly has often worked in high leverage scenarios but isn't consistent or durable enough to serve as a team's full-time closer. That isn't likely to change after signing with the White Sox, which already have Liam Hendriks and Craig Kimbrel as closer options, with Kendall Graveman waiting in the wings.

In his second outing, Kelly threw dangerously close to Alex Bregman and Carlos Correa, drawing an eight-game suspension for instigating a benches-clearing scuffle between the 2017 World Series combatants. Kelly appealed and made five more appearances before being placed on the IL with shoulder soreness. At the time, had yet to surrender a run in 6.1 innings, but with only five strikeouts against five walks. While convalescing, Kelly's suspension was reduced to five games. He returned in mid-September to hurl 3.2 frames, giving up his first two runs while whiffing four with two walks. Kelly has one year left on his contract, so he'll be back with the Dodgers in some capacity. Kenley Jansen is showing signs of decline, but Kelly is no longer next in line. With a drop in velocity along with his K% and BB% heading in the wrong direction, Kelly could be stuck in the middle innings.

Kelly's tenure with Los Angeles started in about the worst way possible, with the right-hander blowing three leads and taking two losses in his first five appearances in Dodger Blue. He was better from there, though the Dodgers had to take measures to limit Kelly down the stretch in the regular season due to poor "overall body" health. While Kelly did end up pitching in the NLCS, he struggled to the tune of six earned runs in 2.1 innings. There were some positives from his 2019 body of work: Kelly lifted his K-rate to a career-high 27.4% while trimming his walk rate to 9.7%. He was one of the most prolific groundball relievers in the game with a GB rate north of 61%, but unfortunately for Kelly, a quarter of the balls that got up left the yard (25% HR/FB). The contract isn't looking great, but Kelly still throws 98 mph and the team will be looking to him to fill a key piece in the bridge to Kenley Jansen.

Kelly endured a roller-coaster 2018 campaign. The flamethrower allowed four runs and recorded just one out in his season debut (in late March) but responded by not allowing a run in April (0.53 WHIP, 10:1 K:BB in 11.1 innings). Kelly's inconsistency continued, as the right-hander posted an ERA north of 8.30 in three of the following months (June, July and September) while keeping his ERA below 1.50 in the other three months (May, August and October), including a 0.79 ERA and 13:0 K:BB across 11.1 playoff frames for the eventual World Series champions. While the 30-year-old saw a jump in his strikeout rate, his 9.3 K/9 still seems somewhat disappointing for a late-inning arm with a 98.5 mph average fastball. Kelly appears primed to serve as Kenley Jansen's top setup man after signing a three-year, $25 million deal with the Dodgers in free agency.

Kelly was coming off of what was arguably the worst statistical season of his career in 2016 (5.18 ERA over 40 innings), but the veteran reliever twirled a dominant final month of the season which helped establish him as one of Boston's more reliable relief arms heading into 2018 campaign. After some offseason mechanical adjustments, Kelly saw his fastball velocity significantly increase to a blistering average of 99 mph. Unfortunately, this uptick in velocity didn't correlate to better strikeout numbers, as his strikeout rate actually fell nearly four percentage points to a very pedestrian 21.9 percent rate. His walk rate remained high (11.3 percent), but he was able to greatly suppress his home-run rate en route to a 2.79 ERA (3.49 FIP) over 58 innings of relief. Despite his improvements, Kelly's still a middle reliever with strikeout and command issues -- that isn't a very appealing combination in fantasy.

Joe Kelly teased the Red Sox in 2016 with his high-90s fastball but would often lose his mechanics, missing the strike zone, and failed to use his secondary pitches enough. In six starts, he had an ERA of 8.46 while giving up 31 hits and 19 walks in 22.1 innings. He was demoted to Triple-A Pawtucket, where the organization decided to transition him to a reliever, a role for which many in MLB thought he was best suited. He took to it quite well, posting a 0.56 ERA in 13 appearances with the PawSox. Kelly continued to be effective when called up in September, putting up a 0.64 ERA while striking out 20 and walking three in 14 innings for Boston to close out the season. He added three scoreless and hitless postseason frames against the Indians. Manager John Farrell attributed his success to an improved slider. His dominant finish to the season sealed Kelly's fate as a full-time, mid-to-late-inning reliever in 2017.

Kelly has intoxicating velocity that keeps him interesting even as he continues to pile up mediocre results. He looked good in 2012-13, but his best work was done in the bullpen while he lucked into good results as a starter despite a 1.6 K/BB ratio in 31 starts. He's been a full-time starter since and the mediocrity has shown itself clearly with a 4.57 ERA and 1.9 K/BB ratio in 231 innings. His best secondary pitch is a changeup that helps him neutralize lefties with just a 29-point platoon split. The problem is that he just allows too much contact leaving him open to variance like the .274 to .320 BABIP jump we saw in 2015. Further exacerbating the issue is that his strikeout pitch - the slider - gets lit up any time it doesn't generate a strikeout (.908 OPS, 33% K rate since 2014). There are some intriguing elements, but his MLB work marries well with his minor league track record so it's hard to project a major jump for him as a starter.

Kelly posted a 2.69 ERA over 37 appearances – 15 starts – in 2013 and opened last season as the Cardinals' fifth starter. There were red flags, particularly with his strikeout and walk rates, as Kelly's xFIP in 2013 (4.19) indicated that a sub-3.00 simply wasn't sustainable. That proved to be true, and while Kelly pitched reasonably well, he was sidelined after three starts by a hamstring injury that kept him out of action for three months. Upon his return, he was hit hard and then traded to Boston in the John Lackey deal. With Boston's starting rotation decimated by trades and the team relying on young starting prospects, the 26-year-old Kelly became the team's No. 2 starter. Even with the offseason changes in the rotation, Kelly is expected to begin the year with one of the five starting spots. He may be ideally suited for the bullpen, where his fastball will have even more velocity (he averaged 94.7 mph on the pitch in 2014) and he won't have to rely as much on his secondary offerings.

Kelly started the season as a long-relief arm out of the bullpen before getting a shot in the rotation at the start of July. Kelly took the opportunity and ran with it, posting an 11-2 record with a 2.32 ERA over his final 14 starts. Despite an excellent showing in the rotation for the Cardinals, Kelly's role for the start of 2014 is murky. The Cardinals have a talented group of young arms to put behind ace Adam Wainwright and Kelly is a good bet to make the rotation next season, but it's far from a guarantee that he will stick if he ends up solidifying a spot when spring training breaks in March.

Kelly started 16 games for the Cardinals last year and threw eight in relief, where he was far more successful. In 91.1 innings as a starter, he had a respectable 3.74 ERA but a not-as-respectable 1.41 WHIP and 59:32 K:BB. Meanwhile, as a reliever, he threw 15.2 innings and finished with a 2.30 ERA, 1.21 WHIP and 16:4 K:BB ratio. Naturally, the Cardinals are planning on using him as a starter this year. He's still just 24, and has room to grow, but it would be nice to see the K:BB ratio improve a bit before throwing him into the rotation for good.
