NEW YORK -- The Mets placed right-hander Jeremy Hefner on the paternity list Tuesday, freeing him to fly home to Oklahoma for the birth of his second child. Hefner's wife, Sarah, is scheduled to give birth on Wednesday, giving Hefner plenty of time to return to New York in advance of Sunday's scheduled start against the Astros.
To replace Hefner in the interim, the Mets recalled lefty reliever Robert Carson from Triple-A Buffalo, where he posted a 1.72 ERA in 10 appearances. With Tim Byrdak out for the season, Carson could receive ample work once rosters expand in September, teaming with Josh Edgin as a second lefty in New York's bullpen.
Because of that, the Mets were glad to afford Carson a bit more big league experience in advance of his September assignment.
"I'd like to try to, if I can, have him face somebody," manager Terry Collins said. "The more times I run him out there, the better idea we'll have. I think obviously there's a pretty good chance he'll be here in September anyway, so it would be good to get him some more time on the mound."
