Overview
- The Pirates placed Griffin on the 10-day injured list for a right forearm/flexor strain, a move the club announced on May 31 and described as likely to be short because he already threw and is progressing.
- General manager Ben Cherington said the team has been cautious, using Griffin as the designated hitter while limiting throws before deciding an IL stint was the prudent next step.
- To fill roster spots the club reinstated veteran Ryan O'Hearn from the 10-day IL and put right-hander Carmen Mlodzinski on the restricted list after he was not ready to pitch.
- Right-hander Cam Sanders was recalled from Triple-A Indianapolis to replace Mlodzinski on the active roster and O'Hearn returned immediately to the lineup as the designated hitter.
- Griffin is a 20-year-old rookie who signed a nine-year, $140 million extension in April and has hit about .270/.327/.402 with four homers and 14 steals in 51 games, so the team says protecting his arm now is meant to preserve his development and availability later this season.
