If the Marlins want Andrew Cashner to succeed, they will need him to keep working with his improved slider.
Part of what made Andrew Cashner an intriguing name in 2016 during the trade deadline was his most recent run of success since returning in July from a neck strain that put him on the disabled list. If the Miami Marlins are to get any value out of Cashner’s remaining half-season with the team and try and justify the gamble of sending away first base prospect Josh Naylor, it will be due to whatever is causing this improvement from Cashner.
