DETROIT — When Giancarlo Stanton left Yankee Stadium after his first homestand in New York amid a crescendoing chorus of boos, there was no shortage of theories as to why the newly acquired slugger had such a miserable first week in the Bronx.

Maybe the jeers — from a homestand in which he had twice fanned five times in a game — had gotten into his head. Maybe he was trying too hard to make a good first impression. Maybe he was not cut out for the scrutiny of New York.

As it turns out, maybe it was something else all together.

Maybe it was the furniture.

When Stanton arrived back in New York on April 1 after the Yankees’ first series of the season, in Toronto, the furniture he had ordered for the apartment he is leasing with Mets pitcher A.J. Ramos had not yet arrived and there were still repairs and upgrades that needed to be done.

That meant that when Stanton was not at Yankee Stadium that week studying video, working on his swing in the batting cages and getting acclimated to his new surroundings, he was unpacking his belongings, working the phones to sort out furniture delivery and lighting upgrades, and making sure everything was all set for a visit from his father, uncle and aunt that week.
