No one said a 4-0 start would mean an easy ride to a successful season.
Mets third baseman David Wright, who jammed his pinky sliding back into first base in Monday night's game, has been diagnosed with a small fracture in the finger.
Wright will not require surgery and can return to action as long as he can handle the pain.
"Worst-case scenario right now is that he is going to miss a little bit of time," manager Terry Collins told reporters after Tuesday's game. "Best-case scenario is ... [he'll be] ready to go on Friday."
Wright iced the finger after Monday's game to try to lessen the swelling, but when it didn't improve he spoke to the Mets trainers Tuesday. He tried to take batting practice, but swinging caused too much pain for him to be effective. He went for an X-ray, where the fracture was discovered.
"I couldn't grip the bat today," Wright told reporters after Tuesday's game. "There was nothing I could do to have it feel even remotely comfortable."
Wright had gotten off to a fast start this season, batting 7-of-12 (.583) with one homer and four RBI in the team's first four games.
The Mets lost 6-2 to the Nationals Tuesday night. It was their first loss of the season.
