Is Tyler Kinley losing his grip on a high-leverage bullpen role? It's a question that's starting to gain traction as the season progresses.

The top of the bullpen has been a bright spot, with arms like Dylan Lee, Robert Suarez, and Raisel Iglesias holding things down. Kinley was part of that trusted group early on, but the last three weeks have been a different story. He's allowed three home runs in that span—two on his slider and one on a curveball—and his expected weighted on-base average (xwOBA) has spiked by over 100 points compared to his first four and a half weeks. Simply put, he's looking hittable.

Interestingly, his expected fielding independent pitching (xFIP) has barely budged, moving from 4.20 to 4.26. That suggests his underlying skills might still be intact, but the results are hard to ignore. When a pitcher starts giving up bombs at this rate, it's fair to wonder if batters have adjusted to his patterns.

So, the big question: is Kinley sliding down the bullpen hierarchy? And if so, who steps up? Could Didier Fuentes take on a single-inning role? Would Aaron Bummer be a better fit for those high-pressure spots? Or does Kinley just need to mix things up and keep hitters guessing? The answer might define the bullpen's pecking order in the weeks ahead.
