The latest Mike Zunino swing update comes complete with a series of pregame checkpoints designed to keep him pointed in the right direction.
"There are drills that I’m doing," he said, "are an actual step-by-step stuff where I can isolate each part of my swing in the cage before batting practice. That way, I know I’ve hit every checkpoint before I go into the game.
"That frees you up going into the game. You know you’ve done that, got it to you liking, and then you can bring it into the game."
The Mariners recalled Zunino on Monday after a 12-game refresher tour at Triple-A Tacoma suggested his swing had stabilized.
