I don’t think Stanton was a full-time DH in 2018. He probably played more games there than usual because he was hampered by some nagging injuries.
Good point.
Stanton’s contract was definitely for an OFer.
Stanton was primarily a DH in 2018, and is expected to be mainly a DH in 2019. The Yankees official MLB depth chart shows him as #1 DH and OF backup. But there is certainly a lot of opinion that says he ought to be the main LFer.
