Walker undergoes successful TJ surgery

Lamb, Souza Jr. and Miller all on the mend

April 25th, 2018

PHILADELPHIA -- D-backs right-hander underwent successful Tommy John surgery on Wednesday in New York.

"Everything went well," D-backs manager Torey Lovullo said. "I've been in touch with his wife and he's resting comfortably. Hopefully, from what I understand, he is going to be leaving the hospital today."

Walker was forced to leave his start against the Dodgers on April 14 after just two innings and was later diagnosed with a tear in his ulnar collateral ligament.

While Walker will be out until sometime during the 2019 season, the D-backs are planning on getting third baseman and outfielder Steven Souza Jr. back much sooner.

Lamb, who is rehabbing from a sprained left AC joint, was recently shut down with right elbow tendinitis. He was re-evaluated Wednesday and the results were encouraging.

"He's going to begin a light throwing program [Thursday] if he gets through today's activity OK," Lovullo said. "He hit in the cage today and did a lot of the on-field things that he was able to do without throwing."

Souza, who has a strained right pectoral muscle and had resumed throwing over the weekend, had Wednesday off. He will stretch out his throwing distance Thursday and continue to hit in extended spring games.

, who is recovering from Tommy John surgery performed last year, threw his first session of live batting practice Wednesday. He could return in June or July.
