That said, Collins was clear to point out that Kyle Farnsworth is still his closer.
Matsuzaka tossed one scoreless inning in relief on Saturday, and three scoreless — and hitless — innings in relief on Sunday. He made only one relief appearance in the major leagues before this weekend.
Farnsworth was named closer in place of Jose Valverde this past weekend. Valverde had taken over for Bobby Parnell, who had Tommy John surgery earlier this season.
