DETROIT -- Mets outfielder Willie Harris traveled back to New York late Wednesday night to be with his wife, Trey, who unexpectedly went into labor five months into her pregnancy.
The Mets placed Harris on Major League Baseball's paternity list following Wednesday's game and recalled outfielder Fernando Martinez from Triple-A Buffalo.
"It's pretty early for the baby, so hopefully she's OK," Mets manager Terry Collins said. "We certainly are thinking of him and her."
Harris learned of his wife's condition shortly before Wednesday's game and flew directly to New York. Under the rules of baseball's paternity list, he must miss at least one game and can be absent for up to three.
Martinez, 22, will fly to Detroit on Thursday for his second stint with the team this season. A former top prospect of the club, Martinez hit .250 during a two-week stretch with the Mets in May and was hitting .266 with six homers in 158 at-bats for Buffalo.
