Shane McClanahan Is Changing Things Up

If there’s anything as inevitable as the Tampa Bay Rays trading away a top starting pitcher, typically for salary reasons, it’s their development of the next one. Shane McClanahan looks a lot like their next one. The Baltimore native was highly effective in his rookie season, putting up a 3.34 ERA and 3.31 FIP with 10 strikeouts per nine over 25 starts in 2021. Even more impressive, he did it with minimal professional experience, with only four games in the high minors before becoming the first pitcher to make his major league debut in a playoff game.
2021 was a fine rookie season for McClanahan, but 2022 is looking like something special. In seven starts, his ERA stands at 2.52, and with a FIP of 2.67, it’s not a BABIP-fueled mirage. His strikeout percentage has jumped by about 40% year-on-year, from 27% to 38%, a notable improvement even in a very pitcher-friendly season. Batters are making both less contact than last year (dipping from 70.4% to 63.6%) and worse contact — their average exit velocity declined from 91.7 mph to 89.3, while their Statcast sweet spot percentage dipped from 36.8% to 26.5%. Among all pitchers with at least 20 innings thrown this season, only Corbin Burnes and Michael King have lower contact rates.
One of the primary differences between this season and last season for McClanahan has been the development of his changeup. Despite a fastball that can hit the high-90s with some nasty late break, McClanahan does not use his heat to finish off batters the way pitchers like Brandon Woodruff or Lance Lynn tend to. In fact, when batters get to him, it’s usually on the fastball, with a batting average well over .300 and 12 of his 19 career home runs allowed coming on the heater. Read the rest of this entry »
