PHILADELPHIA — Daisuke Matsuzaka's rehab assignment is scheduled to end May 23. That's when the maximum 30 days are up.
But under the rules of the new basic agreement, the Red Sox can restart that clock, but it would require activating him before the 30 days are up, waiting seven more days and then placing him back on the disabled list where he'd get another 30 days.
It's an option and Matsuzaka still has one more rehab start to make that decision.
In other matters:
• Jarrod Saltalamacchia appears to be OK after taking a ball off the left ear.
• Cody Ross should be fine after fouling a ball off his left foot, but it was uncertain whether he would be available for Saturday night's game.
