Introducing the New Orioles Bullpen

On April 15 at Camden Yards, the Orioles and Yankees were locked in a stalemate. Both starters had exited, and by the seventh inning, the score remained tied, 1–1. It would be up to each team’s bullpen to keep the game close until their respective bats came alive. The Yankees, of course, sported the league’s finest collection of relievers, a sentiment shared by our preseason positional power rankings. The Orioles bullpen, in contrast, had been deemed one of the league’s worst. A lack of offensive firepower also cast a shadow of doubt on Baltimore’s hopes for victory. It was clear: One side had the advantage, the other did not.
And yet, it was the Orioles who triumphed to secure the win. The projected 28th-best bullpen held its own until the 11th inning, when Ramón Urías drew a walk-off walk against a shaky Aroldis Chapman, bringing a drawn-out conflict to a close. But this isn’t just a one-time, David-beats-Goliath story. As of this writing, the Orioles have the most valuable bullpen in baseball by WAR (I know, it’s early for that, but bear with me). They have the second-most effective bullpen by xFIP. And to really put things into perspective, here’s a comparison between the Orioles and the Yankees:
Metric | Orioles | Yankees |
---|---|---|
ERA | 2.75 | 2.44 |
FIP | 2.95 | 3.07 |
xFIP | 3.27 | 3.56 |
K-BB% | 14.8% | 14.0% |
CSW% | 29.9% | 29.6% |
As expected, the Yankees bullpen has served the team well. But on most fronts, the Orioles’ own unit has kept pace, a fact we can appreciate regardless of how the team is performing. Sure, that’s more mirage than reality. Skeptics can point to an abnormally low home run rate and the fact that it’s early – the Orioles had yet to face a revitalized Mike Trout until Sunday, for example. Consider, though, that Orioles relievers not only own the league’s fifth-highest groundball rate, but also its lowest fly ball rate. In tandem with the altered dimensions of Camden Yards, there’s reason to believe this contact suppression isn’t merely a fluke. They’ve set themselves up for success, in other words.
