Yankees manager Aaron Boone says he doesn't want his players to behave in the same manner as some Dodgers players did after L.A. beat N.Y. in the World Series.

Clayton Kershaw was back on the field with the Los Angeles Dodgers on Tuesday in another sign the three-time Cy Young Award winner is returning for his 18th season with the franchise. The team hasn't announced a contract with the 36-year-old. Kershaw had a locker in the clubhouse but did not speak with reporters.

As it turns out, Yankees manager Aaron Boone didn't enjoy that part. Speaking at the opening of New York's spring training, Boone said he hopes that it's the Yankees who win the World Series this year — and that they do it with "a little more class."
