John Buck's wife is due on Thursday with the couple's child, and Terry Collins indicated there is a possibility the Mets would place Buck on a three-day paternity leave at that point.
Buck noted his wife is in New York, where the Mets return to action Friday. So there is a chance he will not need to be placed on paternity leave, assuming the birth does not conflict with a game.
Collins said top catching prospect Travis d'Arnaud would be a consideration to get called up for the three days if Buck takes paternity leave. Collins did caution that there would be concern about d'Arnaud not being ready for major league pitching, so Francisco Pena or Juan Centeno at Triple-A Las Vegas might be more likely options.
No matter what, Collins suggested, the stay would only last three days.
D'Arnaud has played six Gulf Coast League games since returning from a broken first metatarsal in his left foot, which he suffered April 17. D'Arnaud played with Double-A Binghamton on Wednesday and was 0 for 4.
D'Arnaud is on the 40-man roster, whereas Peña and Centeno are not. But that may not be a major issue, since Peña and Centeno both needed to be added to the 40-man roster this winter anyway if the Mets want to protect them from Rule 5 draft eligibility.
Peña is the son of former All-Star catcher Tony Peña.
