Sean Casey Steps Down as New York Yankees Hitting Coach, Citing Family Reasons

Casey's departure will require Yankees to hire their sixth hitting coach since 2014, after an unsuccessful offensive season marked by numerous lineup holes and internal discord.

Sean Casey, the New York Yankees' hitting coach, announced on his podcast that he will not return to the team next season due to his wish to spend more time with his daughters in Pittsburgh, following his divorce.
Casey replaced the Yankees' previous hitting coach, Dillon Lawson, at the All-Star break; however, the Yankees' batting average only slightly improved during Casey's tenure.
Casey, a former successful big-league player, was appreciated for his personal connection with the players, but was unfamiliar with the analytics the Yankees use in training.
Some believe that the disconnect between Casey's teachings and the minor league approaches led to the second-half struggles of some rookies.
The Yankees are in need of better hitters as the main veterans struggled this season and it is suggested that some of these repairs need to come from trades or free agency in the offseason.
Potential replacements for Casey could include names from within and outside the organization such as Joe Migliaccio, Trevor Amicone, Jake Hirst, Nick Swisher, or Carlos Beltran.
