A’s injuries: Trevor Rosenthal shoulder, Matt Olson knee

On the bright side, Ramon Laureano returned to the lineup

The Oakland A’s have begun to get over a couple of their early-season injuries, but one of them might turn out to be a long-term issue.

New closer Trevor Rosenthal hasn’t pitched yet after going on the injured list Opening Day, and now insider Martin Gallegos offers the following report:

“Bob Melvin says shoulder surgery is on the table for Trevor Rosenthal. He’ll make a decision in the next few days.”

In particular, the operation would be for thoracic outlet surgery, adds Gallegos.

Thoracic outlet syndrome is a major injury for a pitcher. One recent A’s hurler who dealt with it was Andrew Triggs, and you can read more info about the condition and procedure here. It’s something pitchers can come back from, but it takes a while. Matt Kawahara of the S.F. Chronicle suggests “at least 12 weeks” for recovery, which is a minimum of half the season.

“Rosenthal started experiencing tingling in his fingers out of nowhere,” adds insider Jon Heyman.

Olson out of lineup

On the position player side, the lineup was without 1B Matt Olson on Tuesday, and again on Wednesday. Per Kawahara:

Matt Olson has a knee contusion from sliding into the wall chasing a foul ball the other day. MRI showed nothing structural, Bob Melvin said.

Fortunately, it doesn’t sound like Olson will be out for long. He “could be back [Thursday],” per Gallegos.

In the meantime, DH Mitch Moreland covered first base on Tuesday and made multiple excellent defensive plays, reminding us that he also once won a Gold Glove at the position and that he’s a top-notch temporary fill-in when needed.
