The Dodgers sent Kemp, catcher Tim Federowicz and cash (a reported $32 million) to the Padres in exchange for Grandal, pitcher Joe Wieland and pitcher Zach Eflin.
Eflin is expected to be sent along with Dodgers 2013 second-round pick Tom Windle to Philadelphia for shortstop Jimmy Rollins and cash, but that deal hasn't yet been announced.
The deal was reportedly agreed to last Thursday morning, on the final day of the winter meetings in San Diego, but with Eflin involved in both trades and the injury histories of Kemp and Grandal, it understandably took some time. Kemp reportedly took his physical exam on Tuesday.
The delay in the approval of the deal was reportedly the revelation that Kemp has arthritis in both hips. But after both sides talked, the deal went through unchanged, per multiple reports. The bulk of the delay was reportedly for the Padres to work out insurance on Kemp's contract, per Jon Heyman of CBS Sports.
Dodgers general manager Farhan Zaidi was asked on Tuesday if he had any concern about the Kemp and Rollins trades getting completed.
"There is no concern on any deals we have in the pipeline that are contingent on physicals or otherwise," Zaidi said. "Sometimes the logistics of that stretch the process out, but there is no concern on our part."
Kemp, Grandal and Federowicz all tweeted their goodbyes and welcomes last week, but Wieland waited until Thursday night to acknowledge the trade on social media.
