After twice going ahead in the series, the Boston Celtics missed a crucial chance to take a 3-1 lead in the NBA Finals on Saturday morning.
Instead, the Golden State Warriors - spearheaded by Steph Curry - bounced back again, with their 107-97 win in Game 4 leaving the series at 2-2.
The Celtics managed to go punch-for-punch with the Warriors for the first three quarters, but a poor fourth quarter riddled with errors cost the home side, and Jayson Tatum is happy to take responsibility for his side.
The 24-year-old has been a standout performer for the Celtics this season and even managed 23 points, 11 rebounds and six assists on Saturday morning.
But of the Celtics' 16 turnovers during Game 4, Tatum made six of them, and only made 8-of-23 shooting attempts.
"It's on me. I've got to be better," Tatum said.
"I know I'm impacting the game in other ways, but I've got to be more efficient, shoot the ball better, finish at the rim better."
Marcus Smart also noted his side's poor finish to the game, with the 28-year-old - who scored 18 point of his own - suggesting his team lacked "execution".
"We just didn't execute late down the stretch," said Smart.
"They went on a run early on in the third. We sustained it, made a run of our own. After that we just couldn't execute."
The two sides will now effectively play a best-of-three series in the final three matches, starting with Game 5 on Tuesday morning, taking place at the Chase Center.
