Red Sox's Nick Pivetta: Not on mound yet

Pivetta (elbow) continues to play catch but hasn't yet advanced to mound work, Julian McWilliams of The Boston Globe reports.

Pivetta was placed on the 15-day injured list and is first eligible to return Sunday, but he's not yet ready to help a Red Sox rotation that has been hit by the injury bug of late, as Garrett Whitlock (oblique) joined him on the IL this week. It's likely Pivetta will need at least one rehab start before rejoining the club.
