1. Shane Greene's Slider
In the 2016 preseason, there was plenty of hype surrounding Shane Greene's potential as a starter for the Detroit Tigers. While his experiment in the rotation was a major disappointment, he's found a home as a core member of the Tigers' bullpen. Greene's strikeout ability has always been apparent and he displayed it in a big way against the Astros this week. Check out this elegant Slider that curled back over the plate to nip the outside corner for the well deserved punchout.
2. Keone Kela's Curveball
This pitch might not have the same sharpness of break that we see from other breaking balls nor the excessive velocity that makes us gasp. However, we can all marvel at the depth of Keone Kela's deuce as it starts in the middle of the plate before tumbling far far undernearth the zone, forcing Ian Kinsler to take a knee as he whiffs over the pitch.
3. Dellin Betances' Curveball
With Aroldis Chapman on the DL, Dellin Betances has had to change his role from premier set-up man to stud closer and he's transitioned seamlessly. He's still dealing triple digits at times with his Fastball, which makes his unreal Knuckle-Curveball even more effective. Imagine expecting 100mph on the inside corner only to see this pitch fall down into your back foot at the last moment. Absolutely absurd what he can do.
4. Dinelson Lamet's Slider
You may not have heard that Dinelson Lamet made his MLB debut for the San Diego Padres last night and he impressed with eight strikeouts over five frames. He was dialing it up to 98mph at times, while dropping a heavy Slider that took Mets hitters by surprise. Here's a great exhibition of that breaking ball as he got Wilmer Flores to regret his swing on a slide piece that fell right along the outside corner.
5. Tyler Glasnow's Curveball
The impetus for Tyler Glasnow's hype through the minors was his monstrous Curveball, which helped him showcase elite strikeout numbers all through his career. While his command is still in question, he's dropped some filth with his hook through his starts this year, including this pitch to Rio Ruiz that disappeared behind the third basemen in a blink of an eye.
