FanGraphs | Jeff Sullivan: No team sees the same strike zone, on either side of the ball, and some just naturally have more advantageous zones, either by luck or by framing skill. The teams with the most generous zones are the Indians, Rockies, Diamondbacks, Mariners, and Angels.
The Ringer | Zach Kram: The Indians revolutionized the role of the reliever in the way they deployed Andrew Miller, but now with his decreasing effectiveness and injuries, the team that made changing reliever roles so effective... now actually need more relievers to use the strategy at all.
MLB.com | Mike Petriello: Who are the most improved hitters this year? It shouldn’t be a shock that the list includes the likes of Mookie Betts, Francisco Cervelli, Matt Kemp, and Mitch Haniger.
The Athletic | Levi Weaver ($): Is Kyle Boddy’s Driveline a “gimmick”? Based on this piece, you can walk away with the conclusion that it is pseudo-scientific, while others, like Adam Ottavino and Trevor Bauer, believe that his adjustments made them significantly better.
