An official announcement was delayed over Christmas, but the Red Sox and Pirates have now completed the trade sending reliever Joel Hanrahan to Boston.
Along with Hanrahan the Red Sox also receive Brock Holt, a 24-year-old shortstop with good on-base skills who debuted with the Pirates this year.
In exchange for Hanrahan and Holt the Pirates get first baseman/outfielder Jerry Sands, reliever Mark Melancon, and prospects Stolmy Pimentel and Ivan De Jesus.
Hanrahan has been one of the best relievers in baseball since 2010, posting a 2.73 ERA with 10.4 strikeouts per nine innings in 205 appearances, and he saved 76 games during the past three seasons. He’ll be a free agent next offseason.
Sands was acquired by the Red Sox from the Dodgers in the Adrian Gonzalez/Carl Crawford/Josh Beckett trade. He hasn’t hit much in the majors so far, but the 25-year-old has consistently had very strong production in the minors, including hitting .288 with 55 homers and a .914 OPS in 213 games at Triple-A.
Boston got Melancon from Houston last offseason for Jed Lowrie, but he quickly went from setup man to the minors after a brutal start. He returned in June and pitched well with a 4.19 ERA and 40/10 K/BB ratio in 43 innings, so the Pirates definitely bought low on a capable late-inning bullpen arm.
Neither Pimental nor De Jesus ranked among the Red Sox’s top 10 prospects according to Baseball America. De Jesus, who was also acquired in the Gonzalez/Crawford/Beckett swap, has spent most of the past three seasons at Triple-A and projects as a bench player in the majors at age 26. Pimentel spent this season at Double-A as a 22-year-old, throwing 116 innings with a 4.59 ERA and 86/42 K/BB ratio.
