The Cavaliers now have a second Central Division banner hanging in the rafters at Quicken Loans Arena, but there were no celebrations on Sunday.
It had been 33 years since their last division title, but the team is focused on more lofty goals.
"We've got two more to get ? the Eastern Conference championship and the finals," LeBron James said.
Cleveland clinched the division title with a win over Sacramento on Friday night, and are on pace to finish the season with the best record in the East.
