Washington's Jordan Zimmermann overcame a lengthy weather delay to make an impressive major league debut earlier this week. The Nationals' defense could be his biggest problem in his next start.

Zimmermann hopes to help the error-plagued Nationals avoid a three-game sweep by the New York Mets on Sunday when the teams close their series at Citi Field.

Zimmermann (1-0, 3.00 ERA) showed why he was a top prospect for Washington (3-13) on Monday in a 3-2 win over Atlanta. He had to wait over two hours to make his major league debut, but it didn't appear to faze him, as he went six innings, allowing two runs and six hits while striking out three in the victory.

"He was pretty impressive, especially since this was not the nicest day to play baseball," manager Manny Acta told the Nationals' official Web site. "The kid hung in there and was very patient in the clubhouse. He went out there and gave us a tremendous effort."
