The Rays recalled Lopez from Triple-A Durham to start Sunday's game against the Dodgers.
The left-hander will fill the rotation spot of Shane Baz, who was scratched from his scheduled start due to an illness. Lopez has made three appearances out of the bullpen for the Rays this season, and he'll now make his first MLB start of the campaign. The 26-year-old had a 4.08 ERA and 84:33 K:BB across 70.2 innings at Triple-A and has given up five earned runs over 5.1 frames in the big leagues.
