The Red Sox are promoting Double-A hitting coach Johnny Reina to Triple-A Worcester’s assistant hitting coach, I’m told. Reina joined the Red Sox organization in 2024 after working for Driveline.

I hadn’t performed for an audience since middle school. Four weeks of salsa taught me that confidence isn’t born — it’s earned. Check out my second piece in an ongoing exploration of mental skills, growth, and confidence: https://t.co/KAxL7F6XuV

Great thread from @Corsillo11 !

There is a chance Ohtani could make his 100th career start in his 1000th career game. Dodgers, please use a 5-man rotation until mid-September to make this happen.

Ceddanne Rafaela's .989 OPS since late May coincided with cage work he did with Alex Bregman. He hears Bregman’s voice in his head at the plate. “Every time he comes talk to me I just go do what he says and something good happens” On Bregman's big impact https://t.co/2e1rdy99oh

Bregman constantly challenges his teammates to be fully prepared for each at-bat and game. His impact has been felt even as he's been hurt.

Relentless work ethic, intelligent hitter, flat out gritty player. Nobody wants it as bad as him. Jack can absolutely move in the box. No brainer for any program. Go get him!

A man ordered _newspaper fruit_ instead of orange juice. I signed up for salsa lessons. Growth looks weird at first. This is the first piece in an ongoing exploration of mental skills, growth, and discomfort. https://t.co/047VWe9Pqo

"Bat speed doesn't matter. The pitcher provides all the power." Above MLB average bat speed on plane with the descent angle of the pitch allowed Kepler to turn on this Mason Miller fastball and tie the game for the Phils. By the way, bat speed provided about 84% of the EV.
