BALTIMORE — The Boston Red Sox enhanced their thin starting rotation for a playoff run, obtaining right-hander Nathan Eovaldi from the Tampa Bay Rays in a trade for minor league lefty Jalen Beeks.

Eovaldi can become a free agent after this season.

Eovaldi returned this season following Tommy John surgery in August 2016. He’s 3-4 with a 4.26 ERA in 10 starts after starting the 2018 season on the disabled list following arthroscopic surgery on his elbow.
