Injury Notes: Lambo, Harris, Pearce, Mahtook, Brantley, Bautista, Duffy, Richard, Ottavino, Walker

The Athletics announced that outfielder Andrew Lambo underwent surgery recently to treat testicular cancer. Lambo, 27, has seen limited action in four MLB seasons. He has played mostly at Triple-A over the last four years, posting a strong .264/.332/.467 batting line. MLBTR joins all those around the game wishing him the very best as he recovers; we hope to see him back on the field soon.

Here are some injury notes from around the league:

• Cardinals righty Mitch Harris required significant elbow surgery to reattach his ulnar collateral ligament, he announced on Instagram. The 30-year-old cracked the majors last year for St. Louis, providing 27 innings of 3.67 ERA pitching. MLBTR wishes the best of luck to the former Naval officer, who has one heck of a back story.
• The Rays got some more news on the injury front today, as Marc Topkin of the Tampa Bay Times reports (Twitter links). Steve Pearce will hit the DL with a hamstring injury, and could miss around three weeks. Fortunately, it doesn’t sound like the type of hammy issue that is terribly likely to require a truly lengthy absence. Meanwhile, outfielder Mikie Mahtook’s broken hand will not need surgery, meaning that he could return within six weeks — which is better than had been feared.
• The Indians were relieved to find that outfielder Michael Brantley’s latest discomfort is only a bout of biceps tendinitis, Paul Hoynes of the Plain Dealer reports on Twitter. There had been some concern that his surgically-repaired shoulder was showing further signs of trouble.
• Blue Jays star Jose Bautista will need “a couple weeks” in a walking boot after being diagnosed with turf toe, Ben Nicholson-Smith of Sportsnet.ca tweets. That’s largely what was expected when Bautista hit the DL; Toronto will hope that rest and a brief rehab build-up will allow the slugger to return in short order.
• The Giants may be without Matt Duffy for a bit longer than had been hoped, per Andrew Baggarly of CSN Bay Area (on Twitter). He’s expected to wear his own boot for three weeks, and it would seem likely that he’ll need a bit of a build-up from that point on.
• Cubs lefty Clayton Richard hit the DL with a blister issue, per a team announcement. Chicago also optioned righty Adam Warren to Triple-A, where he’ll stretch out as a starter for an upcoming heavy stretch of play. Righty Spencer Patton and lefty Gerardo Concepcion will head up to the big league club to fill in. Of course, it’s fair to wonder how long the Cubs will continue to roll with Richard, who has struggled quite a bit thus far after a solid 2015.
• Adam Ottavino’s rehab has moved to the Triple-A level for the Rockies, Nick Groke of the Denver Post reports on Twitter. That’s good news for the righty as well as the team; Ottavino was emerging as a force in the pen before undergoing Tommy John surgery last year.
• The Mariners announced that righty Taijuan Walker’s foot issue is only tendinitis. He likely won’t require a trip to the DL, as Bob Dutton of the Tacoma News Tribune reports.
