Mark DeRosa! USA Manager & 16-Year MLB Vet on Harper, Trout, Judge & the Next Generation

This week on The JustIn Time Podcast, we sit down with Mark DeRosa—16-year MLB veteran, current MLB Network analyst, and Team USA manager. Mark’s journey from Ivy League standout at Penn to playing alongside Hall of Famers with the Atlanta Braves, and now leading America’s best on the international stage, is packed with incredible stories and wisdom. We reminisce about collecting baseball cards, childhood idols like Don Mattingly, and those pinch-me moments facing legends like Randy Johnson and Greg Maddux. Mark opens up about mentoring Bryce Harper as a rookie, the art of building team chemistry, and the thrill (and heartbreak) of managing Team USA in the World Baseball Classic. You’ll hear candid tales from inside iconic clubhouses, lessons from Chipper Jones and Bobby Cox, and why Mark’s passion for the game—and its next generation—remains as strong as ever.
