Anderson’s change shows excellent drop and armside fade though its velocity separation has shrunk in the last few years to less than 7 mph. While it did generate a decent 12.8% SwStr, it was not a significant source of K’s due to limited usage with 2 strikes. Overall with a .626 OPS against, it proved an effective pitch in 2019 however.
Demonstrating excellent drop and decent horizontal run on his curveball, Anderson went to it just 5.7% of the time in 2019, its lowest usage of his career. Allowing a .427 wOBA, it may be past its prime as it no longer entices a significant chase rate (25%) nor generates significant SwStr (4.7%).
Brett Anderson threw his primary fastballs 49.3% of the time in 2019, with about 86% of those being sinkers, relying on it much more than in years past, and the rest four-seamers. The sinker shows excellent drop and average armside run while his four-seamer also exhibits sinking action though with much less horizontal action. Overall the four-seamer was more effective in more limited action, with a .399 OPS allowed vs. .795, and neither was an efficient source of swinging strikes, though the sinker did produce a healthy 60.4% GB rate, vs 56% for the four-seamer.
Anderson began throwing a cutter for the first time in 2019, and it provided slightly above average results, holding opponents to a .294 wOBA and .092 ISO. Like most of Anderson’s repertoire, it is not a big whiff pitch (4.8% SwStr) with its modest cut and sink and average 88.7 mph velocity.
The primary breaking pitch in Anderson’s arsenal was less effective than it had been in years past, though still overall a decent pitch for him, with opponents putting up a .309 wOBA against. It exhibits good sink with less than average sweeping action for a slider, and with a zone rate of 49% and a 36% chase rate, it generates a 12.1% SwStr, the best of any of his pitches.
Anderson had lots of success with his sinker in 2018, as it posted a career-best 5.2 pVal thanks in large part to the 67.3% ground-ball rate it generated. Opponents hit just .250 with a .300 slugging percentage against it.
As is the case with most of his pitches, Anderson gets a ton of drop on his slider, which helped it post a 59.2% ground-ball rate. Hitters chased it out of the zone 44.4% of the time, helping it post a solid 15.7% whiff rate.
Anderson’s changeup is not deceptive enough to elicit swinging strikes outside the zone or get a ton of whiffs. Consequently, opponents made contact with the pitch 81% of the time and slugged .541 against the pitch.
The four-seamer was solid in terms of velocity and arm-side run, though it was lacking in vertical movement. Opponents made contact with it 89.1% of the time, though, hitting .315 with a .574 slugging percentage in the process.
The horizontal movement on Anderson’s curve was roughly average last year, though the pitch had nearly twice the amount of drop as the average lefty’s. Hitters weren’t fooled by it, though, as it posted just a 6.2% whiff rate and opponents slugged an incredible .864 against it.
