2023 Fantasy Outlook
Kluber was everything the Rays asked him to be, and nothing more. They gave him a one-year deal for $8M with a workload bonus for $5 more, and he exceeded that workload target making all 31 starts with flashes of previous awesomeness while helping mentor the younger upside arms in the rotation. He resumed his stinginess with walks which evaded him in 2021, but the strikeout rate fell to below league average for a starting pitcher and his fastball and cutter were simply too hittable. He went six innings or more in 16 of his 31 starts, which is saying something given Cash's tendencies to pull guys and he still managed a quality start in 15 of his 31 outings. The overall numbers were punished by a handful of rough outings which saw him allow 26 earned runs in 12 innings of work. He may have another serviceable year in him for the Red Sox after he signed another one-year deal, though he'll likely take a step back with Fenway Park being more friendly to hitters and Boston's defense not being anything special.

Kluber (shoulder) feels healthy but will not pitch again this season, Ian Browne of MLB.com reports.
ANALYSIS
Kluber has been throwing off a big-league mound since late June due to shoulder inflammation, but he'd been working his way back, making a pair of rehab appearances for Triple-A Worcester over the last week. With the Red Sox falling out of the playoff race, they won't ask the 37-year-old righty to put more miles on his arm in what have become essentially meaningless games. The fact that Kluber at least made it back for some rehab games bodes well for his readiness for the start of next season, though his 7.04 ERA in 55 innings this season means his opportunities may be limited.

In 80 innings with the Yankees, Corey Kluber posted a 3.83 ERA, 1.34 WHIP, 24% K%, and 9.7% BB%. It's a small sample, but Kluber's fastball velocity dipped to a career-low at 90.3 mph versus 93 mph in his career. In 2021, Kluber mixed in four pitches at a double-digit rate, including the curve/slider and cutter eliciting quality swinging-strike rates with the breaking pitch at 17% and cutter at 13.7%. The breaking pitch continues to possess above-average horizontal movement with 5.8 inches more than the average to induce weak contact with a .243 wOBA allowed. After signing a one-year deal with the Rays, Kluber will provide a veteran presence in the rotation assuming health. Although Kluber probably isn't the 200 innings workhorse at 36 years old, there's a good chance he bounces back in 2022.
Kluber suffered a season-ending shoulder injury early on in 2020, hitting the 45-day injured list following a Grade 2 tear of the teres minor muscle in his right shoulder. He pitched just one inning for the Rangers, fanning one and walking one in a scoreless frame. The 34-year-old has now pitched just 36.2 innings over the last two seasons as a result of various injuries. Kluber's fastball velocity has noticeably declined in recent years, averaging 92.0 mph in his last full season (215 innings). As a result, he's started to rely more on his cutter and curveball, something he'll need to continue on the back nine of his career. The Yankees saw enough during Kluber's January showcase to sign him to a one-year, $11 million contract. It's a nice landing spot from a job security and run support standpoint -- Kluber could be New York's No. 2 starter behind Gerrit Cole -- although performance and health risk abound.
The perils of drafting a pitcher early were realized with Kluber in 2019. One year removed from a 20-win, sub-3.00 ERA season, the Klubot pitched in just seven games with bad results. The first injury was a broken arm from a line drive suffered May 1, and then he had oblique tightness rehabbing from that injury in late August and was shut down for the season. Only twice in the seven starts he made before the injury did Kluber look like himself, and that was on Opening Day against Minnesota and again two starts later against Detroit. The other outings were marred by either multiple homers or uncharacteristic walks. Kluber's fastball velocity continues its decline, and even he recognizes it as he is not throwing it as much as he did earlier in his career. The two-time Cy Young winner will head up the Rangers' 2020 rotation, likely starting the first game ever at Globe Life Field, following a December trade.
Despite another superb all-around campaign, Kluber is eliciting some trepidation from the "better to run away a year early" crowd. The consternation emanates from a marked drop in Kluber's velocity in the final month of the season -- he lost a couple ticks off his four-seamer. The conundrum is he posted his highest swinging-strike rate in September (over 18%), resulting in a monthly-best 35.3 K%. The assumption is September was more fluke than fact and Kluber can't sustain that dominance with less velocity. For the season, he posted his usual stellar ratios, eclipsing the 200-inning plateau for the fifth straight season, the fourth hurling at least 215 frames. Perhaps amassing 1,091.1 regular-season innings the past five years with another 45.1 tacked on in the playoffs has taken its toll, but assuming he doesn't exhibit any health issues in the spring, it's well worth any discount you may get on what should be another elite year.
Despite missing most of May with lower-back discomfort, Kluber won the American League Cy Young Award and joined Max Scherzer and Jeff Samardzija as the only pitchers to toss more than 200 innings in each of the last four seasons. Kluber shattered career bests in both strikeout (34.1) and walk (4.6) percentages, resulting in his lowest ERA ever. While back issues often resurface, there’s doesn't seem to be any real reason to be concerned about Kluber. The righty threw at least seven frames in 19 of his 29 outings. Of the 10 shorter efforts, three were in April as he battled blisters, one was his only May start when his back began barking, two were the games right after he came off the disabled list in June while another was his last start of the season as he was readying for the playoffs. Kluber’s skills and reliability place him among the elite, warranting first-round consideration in leagues that push pitching.
Kluber is wrongly perceived as underrated. He's quiet and prior to 2016, Cleveland didn't get a lot of national run, but that hasn't muted Kluber's price. Consider that he was the 35th overall pick on the heels of his Cy Young win in 2015 draft season and then even after a 9-16 season that saw his ERA rise by a full run, the fantasy market still understood just how good he was and slotted him as the 38th overall pick on average. He rewarded that faith with another Cy-worthy effort that saw minimal erosion in his skills with an ERA and WHIP that essentially split the difference on his 2014 and 2015 seasons. Even with the overall stock of SPs dropping, Kluber will likely set a new best Average Draft Position, going somewhere in the top 30 picks. He has the occasional blowup (five starts of five-plus earned runs), but his eight starts of at least eight innings were third-most in MLB. Those five starts were virtually his only bad ones out of 32. He's elite.
For those still trying to use wins as a measure of pitcher quality, Kluber's 2014-15 should finally convert you. Yes, his ERA jumped by 1.05 runs, but there is no way that was worth nine wins, especially when the skills were actually better in the 9-16 season. He lost a tick on his strikeout rate, but also dropped his walk rate resulting in a slightly better 5.4 K/BB ratio. The most frustrating thing about Kluber's season was that his hot streaks were best-pitcher-in-baseball good and they always seemed to get broken up by a blow-up start. He had 11 starts of eight-plus innings, the most in baseball, but also five starts of five-plus earned runs allowed. Part of the problem is that despite the velocity, Kluber doesn't have a great fastball. It got a bit better last season, but it remains below average, especially for an ace-level talent. The record will definitely drop his cost on draft day, but the fact that you are reading this means you are smart enough not to make that mistake.
Kluber showed devastating secondary stuff throughout 2013 which hinted at a breakout, but his fastball command lagged behind meaning he was no sure thing. Understanding that, Kluber shifted from a four-seamer to a two-seamer and actually gained velocity, giving him a reasonable fastball offering to set up the elite secondaries, the best of which was an incredible curveball that was arguably baseball’s best pitch in 2014. The .241 OPS-against was the best for any single pitch with 150 batters faced and the .091 AVG was second to only Dellin Betances’ breaking ball (.075). It’s hard to believe that Kluber could get better, but if he began commanding his two-seamer like the breaking pitches, then his 2.35 FIP might be in reach. Batters still hit .304 on the two-seamer, but hitting .172 on the rest of his pitches mitigates that damage. He has improved his fastball OPS yearly, down to .821 last year. Another jump could stifle an ERA dip. Even with a backslide in ERA, he’s still a Tier-1 asset.
Kluber stepped into the rotation when Brett Myers hit the disabled list in late April and never looked back. He missed a chunk of time in August with a finger injury and didn't fare well upon his return, but was effective enough overall to pitch himself into the team's plans heading into 2014. Kluber struggles at times with the long ball, but helps out his cause by missing plenty of bats (8.3 K/9) and not allowing many free passes (2.0 BB/9). He'll head into spring training with a spot in the team's starting rotation, and there is very little in the underlying numbers (.329 BABIP., 72.9% LOB, 3.10 xFIP) that suggest his breakout can't be repeated.
Kluber showed better control (3.5 BB/9) and an uptick in his strikeout rate (9.2 K/9) at Triple-A Columbus and earned a midseason promotion to the Indians. He struggled with the long ball in his time with the Indians and does not have the nasty power stuff you might expect from someone his size (6-foot-4, 215 pounds). He will compete for a rotation spot this spring despite some pretty ugly numbers (5.14 ERA, 1.49 WHIP, 1.3 HR/9 in 12 starts) unless the Indians are able to upgrade their rotation options this winter.
Kluber struggled in his first full season at Triple-A (5.56 ERA, 1.480 WHIP, 8.5 K/9IP in 27 starts) despite a nice strikeout rate. The 6-foot-4 righty doesn't have the power arsenal you might expect from his size, and that figures to limit the success he might have if the Indians move him into a relief role. He'll start the season again at Triple-A Columbus, but it doesn't appear that a breakout season is coming any time soon.
Kluber struggled a bit at Double-A Akron after coming over to the Indians from the Padres midseason, but he pitched well enough in the Texas League to warrant some attention. He's always posted nice strikeout totals in his minor league career, but Kluber might get lost in what has become a pretty deep Indians farm system. He was added to the team's 40-man roster this winter, so apparently he did enough to get noticed by the front office and figures to spend most of the year making the jump to Triple-A.
