ST. PETERSBURG, Fla. (AP) — Boston pitcher Junichi Tazawa has rejoined the Red Sox after a few days in the minors.

Tazawa was one of five players called up Tuesday when teams could expand their rosters.

Tazawa was sent down over the weekend. The 23-year-old righty made his major league debut last month and went 2-3 with a 6.65 ERA for Boston. He is set to start Saturday against the Chicago White Sox.

The Red Sox also purchased the contracts of outfielder Joey Gathright and infielder Chris Woodward, and recalled outfielder Brian Anderson from Triple-A Pawtucket. Catcher George Kottaras (lower back strain) was activated from the 15-day disabled list.

First baseman-outfielder Jeff Bailey was designated for assignment.

Also, right-hander Tim Wakefield had a light workout one day after receiving a cortisone shot for his ailing back on Monday.

Daisuke Matsuzaka, out since June 20 with a right shoulder injury, is scheduled to make his third minor league rehab start Friday for Pawtucket.

Manager Terry Francona said Paul Byrd, who made his 2009 debut by throwing six scoreless innings Sunday in a 7-0 victory over Toronto, will start Friday against the White Sox.
