d'Arnaud progressing well from concussion

NEW YORK -- A day after general manager Sandy Alderson could not offer a clear prognosis on concussed catcher Travis d'Arnaud, manager Terry Collins said d'Arnaud has made "a lot" of progress over the course of 24 hours.

"He passed the impact test that we give him. He's passed the physical stuff that we make him go through here," Collins said. "[Thursday] he'll be examined by a doctor and see how he's doing. And then we'll find out what the next step is."

d'Arnaud has been out of action since Alfonso Soriano's backswing caught him on the head May 13. Collins indicated d'Arnaud, once he passes all of the required tests, won't be held back.

"When he's ready to play, he'll be back in there," Collins said.

Left-handed batter Juan Centeno and right-handed batter Anthony Recker have platooned in d'Arnaud's absence. Centeno, who is 3-for-10 with a walk in three games, has been "fine," in Collins' eyes.

"He's handled the bat good. He's a defensive little guy," Collins said. "He's lived up to everything we've seen in the past. He's not a big power guy, but he puts the bat on the wall. He's done fine."
