Adam Rubin breaks the story:
Outfielder/second baseman Willie Harris, who has tormented the Mets in recent years with his glove, will be joining the Mets, a source tells ESPNNewYork.com. Harris has agreed to a minor league deal with spring training invite, but appears a decided favorite to make the team.
Harris has good speed and a nice eye at the plate, but while his defense was exemplary in 2008 as measured by Total Zone and UZR, both metrics found him to be below average the past two seasons.
