Diaz (elbow) has resumed more of his normal baseball activities including hitting and catching, and will begin to throw to bases in the near future, Bill Brink of the Pittsburgh Post-Gazette reports.
Diaz started throwing at 120 feet last week and seems to be progressing well from a right elbow injury that has caused him to miss all of the 2016 season thus far. He decided to undergo surgery in early May and is still on pace to return just after the All-Star break around mid-July.
