🚨PSA🚨 Sport Psychology work is NOT a hobby, it is an evidence-based profession w/academic & professional standards. If you work w/a “mental performance coach” or follow content online, remember that passion, interest & frequency of posts aren’t always indicators of expertise.

@Coach_Enriquez @ABCA1945 Desirable results can certainly help with confidence but since results are uncontrollable and see constantly fluctuating, you run the risk of confidence being unreliable and volatile if it is only being driven by results.

Everyone will touch on the switch pitcher phenomenon, but not enough people will touch on the character Jurrangelo has - cares about his teammates more than himself/wanted the org to be successful. A rare thing in today’s players coming up that gives me hope in future players.

The Seattle Mariners have acquired All-Star Brendan Donovan. Deal is done. Full trade, per sources: Mariners receive: Donovan Cardinals receive: RHP Jurrangelo Cijntje, CF Tai Peete, OF Colton Ledbetter and two competitive-balance Round B picks Rays receive: 3B Ben Williamson
