Perhaps it's only fitting that the signing that took the entire offseason and into the early portion of Spring Training to happen would have a little bit more of a delay before it becomes official. Slugger J.D. Martinez is still expected to walk through the entrance to the Red Sox's clubhouse and put on his new uniform with the familiar No. 28 on the back in the very near future, but there was no grand entrance on Friday. There are procedural issues related to the physical that are still being worked through, prolonging the formal announcement of a five-year, $110 million contract that includes opt-outs after the second and third seasons. The terms of the deal were agreed to on Monday. Friday marked the third straight day the Red Sox hoped to have a news conference, but it now appears Saturday is the earliest that one will take place. Physicals can take varying lengths of time depending on the player, and certainly, the amount of the contract. Martinez had a right elbow injury in 2016 and a sprained Lisfranc ligament in his right foot last year. The Red Sox could be having specialists scanning images to make sure there's minimal risk of those injuries recurring.
