Phillies pitcher Cole Hamels gave up four runs during his season-debut start on Monday in an 8-0 loss to the Red Sox. 

All of the runs Hamels gave up came on home runs as he gave up four. Each run was earned, giving Hamels an ERA of 7.20 to start the season. Hamels went five full innings and threw 100 pitches. 

Hamels struck out six batters and walked three. 

''It's discouraging,'' Hamels said, via the Associated Press. ''You want to get the first win for your teammates and the organization. We didn't get the win and I'm the culprit.''

His next start is expected to take place Saturday against the Nationals.
