The Phillies Send Blue Jays, Vladimir Guerrero Jr Message Amid Bryce Harper Surge The Philadelphia Phillies' resurgence this season has been a welcome respite from their dismal start, thanks in large part to manager Don Mattingly's influence on star player Bryce Harper.
Mattingly's emphasis on "protecting yourself" at the plate has clearly resonated with Harper, who's taken a more measured approach and seen significant improvement.
Mattingly's ability to connect with his players is rooted in his own experiences as a bench coach for the Toronto Blue Jays during their World Series run last year.
