The Orioles’ two best relievers are so because they have two dominant pitches. Their third best is so because he doesn’t have one. Danny Coulombe, unlike Félix Bautista, Yennier Cano and most of baseball’s top relievers, doesn’t have one or two pitches that define who he is. He doesn’t have Bautista’s gravity-defying fastball or devastating splitter, nor does he have Cano’s ground-and-pound sinker or his screwball-esque changeup. Instead, Coulombe is having the best season of his nine-year MLB career and is one of the sport’s top left-handed relievers thanks to an unconventional six-pitch arsenal — one he’s crafted by developing a keen sense of self. “I think that half the battle is figuring out who you are and what makes you good and doing that as much as you can,” Coulombe said. Before this season, Coulombe’s career had been marred by arm-slot changes, mechanical tweaks, pitch-mix tinkering and an injury.
