TAMPA, Fla. — If there was any concern that some residual taint from the Houston Astros’ cheating scandal would follow Gerrit Cole to the Yankees, it was quickly dispelled by his new boss on Thursday.

“None of that came up or has come up,” Yankees Manager Aaron Boone said here at spring training when asked if he had spoken with Cole about the Astros’ illegal sign stealing. “And I don’t think it’s necessary.”

Cole, one of the biggest free-agent acquisitions in team history, joined his new teammates in the first workouts with pitchers and catchers on Thursday. The Yankees gave him a nine-year, $324-million contract with the explicit goal of ending their 10-year World Series title drought, but since Cole spent the last two seasons with the Astros, his first day at the Yankees’ camp featured plenty of talk about the past.

According to M.L.B. Commissioner Rob Manfred’s report in January, the Astros perpetrated illegal sign-stealing schemes that involved using a live-video feed during games to decode opponents’ signs and immediately communicate the next pitch to their hitters, sometimes by banging on a trash can. The bulk of the cheating occurred in 2017, a year before Cole arrived in Houston, but the report said the Astros continued to illegally decode opponents’ signs from a video feed for at least part of the 2018 season.
