Yahoo Sports’ Jeff Passan originally reported early Friday that San Diego was nearing a deal to send the catcher to the Boston for Middlebrooks.
The Padres have already acquired All-Star outfielder Matt Kemp in a five-player deal with the Los Angeles Dodgers, outfielder Wil Myers from the Tampa Bay Rays in a three-team swap, catcher Derek Norris from the Oakland Athletics and Justin Upton from the Atlanta Braves in exchange for multiple prospects.
Middlebrooks, 26, hit .191 with two home runs and 19 RBI in only 63 games as he dealt with a back injury that shelved him for two months last season.
Hanigan’s stint with the Padres most likely will last only two days after he was sent to San Diego from Tampa Bay on Wednesday as part of the deal involving Myers.
Hanigan hit .218 with five home runs and 34 RBI last season for the Rays. He spent his first seven seasons with the Cincinnati Reds.
