Latta is known as a "swing guru" around Major League Baseball. He was Justin Turner's swing coach and believes in "lifting the ball." Rosario, still just 24 years old, hit just .252 with a .643 OPS in 2020. With the emergence of Andres Gimenez there's no guarantee that Rosario remains the Mets' everyday shortstop heading into 2021. Working with Latta could be a reason to buy into a Rosario breakout, though. It's something to take note of for now.
