Boston Red Sox starting pitcher Daisuke Matsuzaka will undergo Tommy John surgery and is out for the rest of the year. The surgery will be performed by Dr. Lewis Yocum, probably next week.
Recovery time for the ligament-replacement surgery, which has become somewhat common around baseball, is usually about one year.
Matsuzaka has made eight starts for Boston this season, going 3-3 with a 5.30 ERA. He is making $10 million this season, the fifth year of his six-year, $52 million deal he signed with the Red Sox to come over from his native Japan before the 2007 season.
