The hit allowed was a single to Mets captain David Wright, who went 2-for-3 in his first game of the Grapefruit League season. The third baseman said keeping his back loose is a little easier in the Florida weather.
"The back felt good today," Wright said. "We'll see how it feels tomorrow."
Giolito was staked to a 5-0 lead in the first inning. Nationals shortstop Danny Espinosa highlighted the explosion with a three-run homer.
Colon was hit hard over five innings, allowing eight runs on nine hits (three homers). But he took it in stride afterward, saying he is working to improve his stuff.
