Patience Is a Virtue for O’s Mountcastle

Last season was a fun one for the Baltimore Orioles. Coming off of five straight sub-.500 seasons and a particularly torturous 110-loss campaign, the Birds had a 24-35 record before starting to turn things around in late June. Just before the All-Star break, they went on an improbable 10-game winning streak to jump over .500, and after the break, they kept the momentum moving their way, even making a short-lived run at the third American League Wild Card spot (they ultimately fell just three games short). It started to look like the dawn of a new era in Baltimore, and much of the spark came from a revamped lineup. Adley Rutschman and Gunnar Henderson made their highly anticipated big league debuts and did not disappoint – particularly the former, who turned in one of the finest rookie seasons by a catcher in recent memory. Cedric Mullins followed up his breakout 2021 with another solid season. Anthony Santander set a new career high with a team-leading 33 home runs. And then there was Ryan Mountcastle.
After leading the Orioles with 33 homers and 89 RBI in 2021 in his full-season debut, Mountcastle’s offensive production faded last season. He hit just 22 home runs, while his slugging dropped from .487 to .423, his wOBA from .335 to .316, and his wRC+ from 111 to 106. His defense improved enough to allow him to reach 1.6 WAR, a new career high, but for a player whose calling card is power, his waning surface-level thump was at least indicative of a sophomore slump and at most a cause for concern.
But Mountcastle’s Statcast profile and expected stats tell an entirely different story. In 2021, the slugger was in the middle of the pack, with an average exit velocity of 89.1 mph (45th percentile) and a 39.7% hard-hit rate (41st); his .245 xBA and .326 xwOBA placed him in the 36th and 47th percentiles, respectively. By these measures, his 2022 was one of the better year-over-year improvements in baseball. He added 2.2 mph to his average exit velocity, the seventh-largest increase among players who qualified in both years, and 6.6 percentage points to his hard-hit rate, the sixth-most in that group. Just four hitters added more to their xBAs than his .032 points, and the only hitters who managed to improve their xwOBAs more than his .036-point jump were Yordan Alvarez (.073), Christian Walker (.048), and Aaron Judge (.045). His was one of just 40 player-seasons in the Statcast era with 60-plus barrels. Read the rest of this entry »
