Isaiah questions lack of calls after not reaching foul line in Game 4

The Boston Celtics and Washington Wizards are back to square one in their series, tied at two games apiece. In Washington's consecutive wins in Games 3 and 4, Celtics star Isaiah Thomas was held to 13 and 19 points, respectively.

That's the first time this season Thomas has been held under 20 points in consecutive games, but after Sunday's 121-102 Wizards win, he questioned why he never got to the free-throw line in the contest.

"The refs were allowing (the Wizards) to hold and grab," Thomas said, according to ESPN's Chris Forsberg. "I might have hit the ground five or six straight times and I'm not the one that likes hitting the ground. It's gotta be called differently ... I don't even shoot one free throw."

Thomas shot well in the contest - 50 percent from the floor and 5-of-6 from deep - but didn't get any calls despite drawing contact. He only scored two of his 19 points in the second half, when the Wizards sealed the game with a 26-0 run. Thomas confessed he just didn't get good looks, and credited the Wizards' adjustments.

"They also paid a lot more attention to me," the 5-foot-9 guard said. "They didn't allow me to get any open looks after a little bit of the second quarter, and as a team we've got to do a better job of figuring that out."
