Nick Cafardo of the Boston Globe has the goods:
Teams like the Astros and Mets are kicking around the possibility of adding Matsuzaka to their spring training camp to see if he can recapture the form he had in his first two seasons in Boston. Matsuzaka could also head back to Japan if he doesn’t get what he considers a good chance to make a major league roster.
In other words, his best bet here in the states is a non-guaranteed minor league contract and spring training invite. Matsuzaka posted a hideous 8.28 ERA and 1.71 WHIP in 45 2/3 innings last summer for the Red Sox. He hasn’t been an effective pitcher since 2008, when he had a 2.90 ERA in 167 2/3 frames.
But rebuilding teams like the Astros and Mets can afford to take some risks this season.
