There have been a handful of MLB trades to take place this week, and the Pittsburgh Pirates are getting into the action with a notable deal completed with the Boston Red Sox.
Per Ari Alexander and other reports surrounding the Red Sox/Pirates, the Pirates are sending left-handed pitcher Joe La Sorsa to the Red Sox It’s unclear what the return is for Pittsburgh, but La Sorsa is set to join the Red Sox tomorrow for their upcoming series with the New York Yankees.
MLBTR.com’s Darragh McDonald was on this news very quickly, and had this to say about the deal:
“It was reported a few days ago that the southpaw was triggering an upward mobility clause in his minor league deal. Alexander says that La Sorsa will be with the Sox in New York tomorrow as they kick off a series against the Yankees. Boston will need to open a 40-man roster spot for La Sorsa. Itâs unclear what the Bucs are getting in return but it could be a cash deal.”

“Trade: the Red Sox have acquired lefthanded reliever Joe La Sorsa from the Pirates, according to Ari Alexander. He has a 3.81 ERA in 26 AAA innings but triggered an upward mobility clause. He will be active with the Red Sox in New York.”
It’s a small trade across MLB, but as always, every move can be notable for at least one side.
