"Thank goodness it doesn't count now," Hamels said.
The damage started in the second, when Hamels allowed four runs to hand the Dominican Republic a 4-0 lead. Hamels allowed a leadoff double to Hanley Ramirez before Miguel Tejada, Carlos Santana and Ricardo Nanita hit consecutive singles. Hamels retired Alejandro De Aza and Jose Reyes for two outs, but Robinson Cano and Edwin Encarnacion hit back-to-back singles to plate a couple of more runs.
Hamels finally struck out Nelson Cruz to end the inning, but not before everybody in the lineup had batted. Hamels allowed four more runs before being pulled in the third.
Phillies designated hitter Laynce Nix hit a solo home run to right field in the second.
Phillies up next: Right-hander Roy Halladay will pitch against the Nationals at 1:05 p.m. ET on Wednesday at Bright House Field in a game that will air on MLB.TV. Halladay is making his third Grapefruit League start as he attempts to fine-tune a few things and rebound from a disappointing 2012 season.
