Red Sox purchased the contract of LHP Justin Thomas from Triple-A Pawtucket.
Thomas had a 6.75 ERA and 9/4 K/BB ratio over 10 2/3 innings this spring, so it’s not like he’s been lights-out, but Andrew Bailey’s thumb injury has opened up a spot for a second left-hander. He’ll likely be used in the middle innings and lower-leverage situations while Franklin Morales figures to be more of a late-game option.
