Injury Notes: Giants, Red Sox, Indians, Jays, Jankowski

The Giants announced tonight that right fielder Hunter Pence has been placed on the 10-day disabled list due to a left hamstring strain. Fellow outfielder Mac Williamson is up from Triple-A Sacramento to take Pence’s spot on the roster. The loss of Pence is the latest blow to a Giants roster that has seen a number of key players go down with injuries this year, though Pence’s performance hasn’t been anywhere near what one would expect from the typically productive slugger. The 34-year-old has been at least 18 percent better than the league-average hitter in each of the past four seasons, per park-adjusted metrics OPS+ and wRC+, and he’s batted a combined .281/.339/.463 in that time. However, this year, he’s mustered just a .243/.289/.338 batting line through his first 149 plate appearances.

A few more notable injury scenarios from around the league…

• Giants closer Mark Melancon is on the mend and appears to be progressing well, as the right-hander told reporters that he threw a 22-pitch mound session today (Twitter links via John Shea of the San Francisco Chronicle and Alex Pavlovic of NBC Sports Bay Area. Melancon said that he was “pretty much full go,” and Pavlovic notes that he can be activated as soon as tomorrow. Derek Law has been filling in as San Francisco’s closer with Melancon on the shelf.
• An MRI of Drew Pomeranz’s left triceps didn’t reveal any new injuries, and the Red Sox lefty has been cleared to resume baseball activities, tweets Alex Speier of the Boston Globe. News on Tyler Thornburg, though, isn’t as good. The Sox are still trying to get to the bottom of the shoulder woes Thornburg is experiencing, as Evan Drellich of CSNNE.com tweets. Thornburg is set for additional testing and medical consultations this week. He has yet to take the hill since arriving in Boston via trade over the winter.
• The Indians will be without Brandon Guyer for the next four to six weeks due to a sprained left wrist, manager Terry Francona told reporters today (via MLB.com’s Jordan Bastian). Guyer will be completely shut down for a week before he begins the next phase of his rehab. Bastian also notes that ace Corey Kluber tossed a 20-pitch session today but still needs a more aggressive mound session and a simulated game before he’s cleared to begin a rehab assignment. And if those injuries aren’t enough for Cleveland, the Indians’ No. 2 starter, Carlos Carrasco, exited tonight’s game with tightness in his left pectoral muscle (Twitter link via Bastian). There’s no word on the severity of that issue, though it seems reasonable to expect further word following the completion of tonight’s game.
• Steve Pearce became the latest member of the Blue Jays to land on the disabled list, as the infielder/outfielder suffered a calf injury last night and was placed on the 10-day DL today following an MRI. The Jays announced the injury as a right calf strain and did not offer a timeline on Pearce’s absence. Right-hander Leonel Campos is up from Triple-A to give the relief corps a quick boost, though as Sportsnet’s Ben Nicholson-Smith tweets, that gives the Jays a two-man bench and a nine-man bullpen. As such, it seems likely that a reliever will be sent down soon. On a more positive note for Toronto fans, the team also announced that Troy Tulowitzki began a rehab assignment today, suggesting that he’s quite near to a return.
• Padres outfielder Travis Jankowski has been on the DL since late April, and MLB.com’s AJ Cassavell now tweets that it’ll be at least another six weeks before the defensive standout is ready to return to the team. Jankowski hit the DL with what was termed a “deep bone bruise,” though reports at the time suggested that doctors believed there could be a hairline fracture in his foot. Per Cassavell, Jankowski’s most recent tests did indeed reveal a fracture, which lengthens the amount of time that he’ll be away from the club.
