La Sorsa was designated for assignment by the Rays on Saturday.
La Sorsa allowed one run on three hits in 2.1 innings of relief in the first half of Saturday's doubleheader against the Red Sox. That was the first run he gave up in 4.1 innings at the big-league level this season. The long-relief effort means he won't be ready to pitch again for a few days, so he'll be the one to lose his roster spot as the Rays bring in fresh arms for the nightcap.
