BUFFALO, N.Y. – Daisuke Matsuzaka pronounced himself ready to return to the Boston Red Sox rotation after throwing six scoreless innings in a minor league rehab start.

“I think I’ve thrown enough pitches at this point to be ready to pitch in the big leagues,” Matsuzaka said through an interpreter. “When compared to the second time I went on the DL last year, it took me a really long time to have that feeling. You can’t even compare them right now. I’m confident I can pitch in the big leagues.”

Matsuzaka is on a 30-day rehab assignment because of a neck strain. He is scheduled to pitch again for Pawtucket on Tuesday at Rochester.

On Thursday, he allowed three hits, struck out two and walked none against the Buffalo Bisons. He threw 86 pitches.

“I think, just like my last start, my arm action was pretty good,” Matsuzaka said. “I wanted to work on being able to make adjustments on my breaking pitches today. Compared to my last outing, I think I was able to do that. Today I was able to use the slider with my normal arm action and it seemed to do the work on its own so that was great.”
