Summary:
There’s a lot to like in Bresnahan’s foundation as a left-hander, starting with a clean, athletic delivery and a fastball that has taken real steps forward. The heater now works comfortably in the 93–96 range and is thrown with solid control, particularly to the outer half, allowing him to stay on the attack rather than nibble. The delivery produces extension and a tough angle, helping the fastball play up without needing elite raw velocity, and the overall operation supports continued strike-throwing as he moves up.

The changeup is the clear separator in the arsenal and already flashes as a true weapon. It sits in the mid-80s with late fade and feel, and when he’s landing it, it gives him a reliable answer to right-handed hitters. The slider has improved as well, showing more consistency and trending toward an average offering, though it can still get loose and break early at times. As his strength and feel continue to develop, the slider’s ability to tighten shape and stay on plane will be a key indicator of how deep the mix can play.

Taken together, the profile points toward a starter track with real upside. The fastball/changeup pairing provides a strong backbone, and the combination of physical projection, athleticism, and strike-throwing gives him a chance to settle into a mid-rotation role if the slider continues to firm up and a fourth look emerges. Without that next step, the floor remains useful, but the ingredients are there for more as he climbs the ladder.
