The move dropped Wednesday night, confirmed simultaneously by MLB Trade Rumors and Mark Feinsand. The Dodgers activated Edwin Diaz from the injured list, ending a stretch that's kept the three-time All-Star closer off the mound since mid-April.
Feinsand broke the Diaz activation alongside another injury update out of Philadelphia.
Two NL health updates: The Dodgers have activated Edwin Diaz from the IL. The Phillies announced that Brad Keller underwent right elbow ulnar collateral ligament reconstruction with internal brace and flexor tendon repair surgery. Timeline to return is 13-16 months.
This isn't a tweak-and-return situation. Diaz underwent right elbow surgery back on April 22 to clean out five loose bodies he'd apparently been pitching through for his entire career. He said he started feeling "tired and tight" after an outing against Colorado just days before going under the knife. That's a scary phrase for a guy whose whole game is built on a triple-digit fastball and a slider that misses bats.
The rehab process took months. Diaz didn't begin his minor league assignment until July 11, then made seven appearances spread across Triple-A Oklahoma City, Single-A Ontario and the Arizona Complex League, posting an 11-strikeout, 3.18 ERA line over 5.2 innings before wrapping it up on July 26. Three days later, he's back in a Dodgers uniform.
MLB Trade Rumors put the official transaction on record as it broke.

His return immediately reshuffles the bullpen pecking order. Tanner Scott had been holding down the closer role while Diaz recovered, and now slides back into more of a setup or fireman spot as Diaz reclaims the ninth inning. For a Dodgers team that's leaned hard on its relief corps all year, getting a healthy, dominant closer back is exactly the kind of boost you want walking into August.
The timing matters. The trade deadline lands August 3, and the Dodgers' bullpen being whole again gives the front office more flexibility to focus resources on the rotation, where the real work is happening. Los Angeles has been floated as the favorite for Tarik Skubal, a pursuit that's only gained urgency with Shohei Ohtani's knee still keeping him off the mound. On the other end, Eric Lauer is widely expected to be dealt once Blake Snell is fully back, continuing what one insider called a pattern of the Dodgers trading away a big-league starter at the deadline for a fourth straight year.
Bottom line: the Dodgers just got healthier where they were already deep, which frees them up to chase what they're actually short on. A full-strength Diaz doesn't fix the rotation questions, but it takes one variable off the board heading into a deadline that's shaping up to be busy.
