Late season trades can haunt fanbases. On August seventh of 2014, the Los Angeles Angels traded a pitcher in Class-A for reliever Vinnie Pestano. Cleveland worked its magic on Mike Clevinger culminating in a career year in 2019 in which he went 13-4 with 169 strikeouts against 37 walks over 126 innings with a 2.71 ERA, 3.09 ERA and 1.06 WHIP in perhaps the most hitter friendly environment on record. He missed with time with two separate injuries, an upper back strain and a sprained ankle.

Prior to his back strain, Clevinger notched 12 shutout innings with 22 strikeouts against four walks. Upon his return, he suffered an ankle injury in June sidelining him again. However, it’s what Clevinger accomplished between July 3rd through September 24th. Within these 102 innings, Clevinger won 12 of his 13 decisions with 134 strikeouts against 25 walks, a 1.76 ERA and 1.02 WHIP. His strikeout percentage rose to 33.6 percent with a .212 batting average allowed, 2.27 FIP and 2.98 xFIP.

What fueled Clevinger’s breakout presents the root of this profile. It starts with adding velocity to his four-seam fastball. In 2017, Clevinger averaged 92.5 MPH with the pitch which increased slightly to 93.6 MPH in 2018 and spiked to 95.4 MPH last season. Although he only made 21 starts, it’s worth noting the added speed to the pitch. He also used fewer change-ups, possibly due to the lower seams on baseballs in 2019 while ramping up his slider usage. These adjustments yielded his strikeout percentage growth to 33.9 percent. Here’s his pitch plot from last year courtesy of Statcast:

Clevinger’s arsenal allowed him to work well both in and out of the strike zone. This, along with his increased fastball velocity contributed to his breakout. In an effort to discern how his pitches fared, check out their expected numbers with expected batting average (xBA) and expected weighted on-base average (xwOBA) plus strikeout percentage along with whiff percentage:

  • Four-seam Fastball - .203 xBA, .283 xwOBA, 36.1 strikeout percentage, 30 percent whiff rate
  • Slider - .159 xBA, .210 xwOBA, 40.6 strikeout percentage, 48.3 whiff rate
  • Curve - .243 xBA, .271 xwOBA, 32.7 strikeout percentage, 32.4 whiff rate
  • Change-up - .290 xBA, .315 xwOBA, 11.5 strikeout percentage, 33.6 whiff rate

For perspective, building on the first chart, Clevinger’s swings and misses from 2019 by pitch:

Using his fastball more than 50 percent of time helped Clevinger work ahead on the count and he owned the shadow zone displayed here on Statcast’s swing and take chart:

Clevinger owned the third best swing and miss rate with his four-seam fastball and the fourth best slider according to’s end of season game notes. Brooks Baseball provides a glimpse of how he used these two pitches in 2019:

When ahead in the count versus left-handed hitters, Clevinger used his curve but relied on the slider against right-handed batters. Beneath all of this, Clevinger increased his whiff percentage by 7.4 percent on Statcast while his swinging strike percentage on Fangraphs rose to a career best 15.2 percent. He reduced contact to 66.7 percent, down 7.4 points compared to 2018 and decreased Z-Contact (in the strike zone) by over six percent.

Although the Twins and White Sox continue to strengthen their lineups, Mike Clevinger still rates as one of the top pitchers in fantasy going forward. Everything looked great for him heading into drafts until this:



Now fantasy owners will need to determine if Clevinger’s worth the risk. Here’s his projection:

  • Mike Clevinger 2020 Steamer Projection - 12 - 8, 167 IP, 202:57 K:BB, 3.67 ERA, 3.85 xFIP, 1.19 WHIP
  • Mike Clevinger 2020 THE BAT Projection - 12 - 8, 170 IPm 210:56 K:BB, 3.43 ERA, 1.14 WHIP

Prior to Cleviger’s surgery, his projection of 197 innings rated just below the elite with 200 inning or more. Injury issues aside from 2019, Clevinger’s breakout appears sustainable assuming his fastball velocity gains stick and his arsenal continues to evolve. With pitching prices escalating in fantasy, one must adapt to the new environment. There’s some risk with Clevinger compared to his price point, and guessing his price does not drift too far as a result of the surgery. If he finishes closer to an ERA near three using his 3.09 xFIP from 2019 as a reference point, Clevinger’s THE BAT projection will be the basis for the Clevinger believers. For owners looking to target two aces early, Clevinger makes for an intriguing investment with some upside still untapped, especially if he comes with a discount.
