Yankees manager Aaron Boone said Giancarlo Stanton (calf) underwent an MRI that didn't show enough progress to begin ramping up baseball activities.

It doesn't technically qualify as a setback, but Stanton won't be returning to New York's lineup as quickly as initially envisioned. The 36-year-old designated hitter remains in a holding pattern until his calf strain shows enough healing that he's cleared to resume running. His ongoing absence means strikeout-prone prospect Spencer Jones will get a longer opportunity to show something at the highest level than originally thought.
