PITTSBURGH — A Pittsburgh Pirates relief pitcher will look outside of the franchise for his ultimate goal this season.Pirates left-handed relief pitcher Joe La Sorsa is choosing to exercise his upward mobility clause on June 1, according to Ari Alexander of 7News Boston, where he'll try to find a MLB team that wants his services.An upward mobility clause, when a player triggers it, allows the other 29 MLB teams to take a chance on them and add them to their roster. The Pirates then have to trade La Sorsa to a team that wants him or he'll remain at Triple-A Indianapolis if no MLB team takes a chance on him.Could a MLB Team Take a Chance on La Sorsa?La Sorsa already triggered his upward mobility clause back before the season started, when the Pirates optioned him to Triple-A Indianapolis before Opening Day, but no team picked him up.The Pirates signed him on a minor league deal this offseason and made him a non-roster invitee to Spring Training, where he posted a 2.25 ERA over four appearances in the Grapefruit League.Mar 8, 2026; Houston, TX, United States; Italy pitcher Joe la Sorsa (75) pitches against Great Britain in the fifth inning at Daikin Park.
