Found a Brasier-stan on Twitter:
@RRyanmedeiros
Batted-ball data shows that Brasier was incredibly unlucky in ‘22.
He had the 8th-highest differential in MLB (1.80) between ERA and xERA (3.97).
But the Sox aren’t keeping just him around to show sympathy for his poor luck
Brasier's slider was the 10th most effective pitch on Boston’s staff (-5 run value) and the best offering in his arsenal by far (.262 xWOBA).
But he couldn't establish a strong secondary pitch - fastball was 8th worst pitch by a Sox P (+8 RV) and sinker wasn’t far behind (+7).
Brasier's 4-seam actually amassed a much better run value than his slider from 2018 until 2022 (4SM (-12) / SLD (-4)).
He entered the '22 season throwing 50% 4-seamers, but the early results were so poor (.385 BA / .692 SLG) that he began to mix in the aforementioned sinker.
In September, Brasier started throwing his fastball more often again (46%) and the results were excellent (.162 xWOBA on 73 deliveries).
Brasier had a 1.80 ERA and 0.50 WHIP in 11 September appearances.
The Red Sox front office recognizes the value he can bring if he continues to combine good fastball location with his plus slider.
Now you might too.
Per Cotillo, the other DFA's so far have been: Almonte, Reed, Bazardo, McGee, Hamilton, Reed, Cordero, Chang, Park, Downs, Hosmer, Darwinzon, Seabold. Not exactly a list of guys that still need to be around.
