Tom Koehler undergoes season-ending surgery, Puig and Baez to join Dodgers Thursday

The Dodgers had a slew of injury updates before Tuesday’s game in Philadelphia, starting with the announcement that right-hander Tom Koehler had undergone season-ending shoulder surgery.

Koehler, 32, was viewed as a late-inning reliever that could fill the void left by Brandon Morrow’s departure to Chicago. But that plan never came to fruition after Koehler was diagnosed with a mild anterior capsule strain in his throwing shoulder back in spring training.

After a few months of rehab and setbacks, surgery was the best option for the reliever as he will go the whole season without throwing a pitch. The Dodgers signed Koehler to a one year, $2 million deal in the offseason.

Wild Horse Update

According to manager Dave Roberts, Yasiel Puig and Pedro Baez will be activated ahead of Thursday’s game in Atlanta.

Puig has been on the disabled list since coming out of a game in Anaheim July 8 with a Grade 1 right oblique strain. The team didn’t place an initial timeline on how long it would take for his return, but similar strains have taken a month or more.

The Dodgers sent Puig to their spring training facility last week to take some swings and he will go on a rehab assignment Wednesday with Triple-A Oklahoma City.

Baez has been on a rehab assignment since July 17 with OKC after last throwing a pitch in the big leagues on June 9. The right-hander has been dealing with what the team described as right bicep tendinitis.

More injury progress

Dodgers’ lefty Hyun-jin Ryu, sidelined since exiting a start May 2 with a left-groin strain, is set to go on a rehab assignment of his own sometime next week. Roberts indicated that the 31-year-old would need at least four starts before returning to the big club.
