BOSTON -- Left-hander Pedro Hernandez was roughed up for eight runs on 12 hits in his major-league debut, and the Boston Red Sox rolled to a 10-1 victory over the White Sox on Wednesday at Fenway Park.
Hernandez, the 10th pitcher to start a game for the Sox this season and the ninth rookie to pitch, was brought up from AAA Charlotte to fill a void in the starting rotation left by Gavin Floyd's move to the disabled list on Monday.
Cody Ross hit two three-run homers against Hernandez, and Adrian Gonzalez added a solo shot after Ross' second blast. All three homers cleared the Green Monster in left field.
The division-leading Sox (50-41) lost ground in the American League Central to the Detroit Tigers, whose victory against the Angels pulled them to within 2 1/2 games of the Sox.
Paul Konerko, playing in his 2,000th game in a White Sox uniform, singled in the Sox' run with an opposite field single in the first inning against Boston starter Felix Doubrant (10-4).
The White Sox were held to four hits. The fourth and final game of the series is Thursday night.
Hernandez, 23, was acquired along with pitching prospect Simon Castro from the Padres during the off-season in a trade for outfielder Carlos Quentin. He was 7-2 with a 2.90 ERA between AA Birmingham and Nashville.
