>>Harvey Sharp In First Regular Season Start In Year and a Half
In his first regular-season start after Tommy John surgery, Matt Harvey tossed six scoreless innings, allowed just four hits, struck out nine and walked one, as the New York Mets held on to defeat the Washington Nationals, 6-3, on Thursday afternoon.
Harvey last pitched in a game 593 days ago and his return was exactly what the doctor ordered for the revamped Mets, who won two of three in this season- opening series from the defending NL East champions.
He threw 91 pitches, striking out Washington slugger Bryce Harper three times, and outdueled Stephen Strasburg in a rare battle of aces in the third game of the season.
David Wright had two hits and two RBI, while veteran free agent addition outfielder Michael Cuddyer also had two hits and drove in a run. Travis d'Arnaud also came through. D'Arnaud went 2-for-4 with two RBI.
Strasburg (0-1) suffered the loss, allowing six runs -- three earned -- on nine hits over 5 1/3 innings. The right-hander, who has also had Tommy John surgery, struck out five and walked three.
Ian Desmond had a rough series for Washington, committing his third error of the series in the third inning leading to a four-run frame for the Mets.
