Mookie Betts is frustrated with his slow start to the season.

"Basically, what I'm doing is unacceptable," the reigning American League MVP said. "I have to figure out a way to get something done and help the team."

The Red Sox are 6-11 and Betts is slashing .222/.324/.413 and has three homers and seven RBIs.

"I wouldn't say it's more pressure, but I know I'm definitely -- there have been many times where I can help score runs or do something and I haven't done it," said Betts. "I take full ownership of that."
