Brusdar Graterol, Joe Kelly begin season on the injured list

The Dodgers made official their opening day roster on Thursday morning, with a few final transactions to get down to the 26 active players for the series against the Rockies in Colorado.

Chief among them are relief pitchers Brusdar Graterol and Joe Kelly each on the 10-day injured list to open the season, Kelly with right shoulder inflammation.

Neither Graterol nor Kelly pitched in a game this spring, and didn’t accompany the team to Los Angeles when camp broke. When they might return to the Dodgers is unknown.

“I don’t want to take a stab at a timetable,” manager Dave Roberts said on Tuesday. “I think Brusdar is ahead of Joe, but what that means, I really don’t know.”

Both were slow-played in Arizona, Graterol because he was behind in his throwing program at the start of camp.

“There’s a lot of things that took place this winter for Brusdar that didn’t allow for him to prepare like he normally would have, as far as throwing bullpens to prepare for spring training. The last thing we want to do is speed him up when he’s not ready,” Roberts said earlier in camp. “The main thing is that we just want him to be healthy and progress the right way.”

That gives the Dodgers four players on the injured list to open the season, along with Caleb Ferguson and Tommy Kahnle, each of whom is on the 60-day injured list and recovering from Tommy John surgery.

The Dodgers are opening the season with 13 pitchers and 13 position players on the roster.
