BOSTON (AP) — The Boston Red Sox have acquired closer Craig Kimbrel from the San Diego Padres for four prospects.

The Red Sox assume $25 million remaining on Kimbrel's contract in their first big acquisition since Dave Dombrowski took over as president of baseball operations on Aug. 18. Kimbrel was obtained by the Padres in a blockbuster deal the day before the 2015 started.

The deal was announced Friday night.

Kimbrel had 39 saves in 43 chances for the Padres, who underachieved despite a roster makeover by general manager A.J. Preller.

The Padres receive outfielder Manuel Margot, infielders Javier Guerra and Carlos Asuaje, and left-hander Logan Allen.

Asuaje spent 2015 with Double-A Portland, Margot split the season between Class A Salem and Portland, and Guerra was with Class A Greenville. Allen, Boston's eighth-round draft pick, split time between Boston's rookie-level affiliate and Class A Lowell.
