ANAHEIM, Calif. -- The Los Angeles Angels exploded for seven runs in the second inning, and coasted to an 11-1 win over the Boston Red Sox Monday afternoon in the first game of a doubleheader at Angel Stadium.

The Angels scored all seven runs in the span of just eight pitches thrown by Red Sox starter Eduardo Rodriguez (5-3), who didn't make it out of the inning.

The Angels' onslaught included a two-run single by second baseman Johnny Giavotella, a two-run homer by right fielder Kole Calhoun, and a solo homer by designated hitter Albert Pujols.

Third baseman David Freese hit a three-run homer in the fourth inning.

The outburst was more than enough for Angels starter Hector Santiago, who was making his first start since being named to his first All-Star team. Santiago had to work hard, making 114 pitches in just five-plus innings to get the win and improve to 7-4.

He struck out 10, tying his career high, and they included key strikeouts in the first and fourth innings.

In the first, the Red Sox had runners on first and second with one out, but Santiago struck out designated hitter David Ortiz and left fielder Hanley Ramirez.

In the fourth inning, the Red Sox already had scored one run on first baseman Mike Napoli's RBI single, and had the bases loaded with one out. But Santiago struck out catcher Ryan Hanigan and center fielder Mookie Betts to escape again.

In all, Santiago gave up one run on eight hits and one walk.

The Angels finished with 11 hits, including two each by Pujols and shortstop Erick Aybar.

NOTES: Monday's doubleheader was the first at Angel Stadium since Sept. 6, 2003, when the Angels played the Royals twice, including one that was a makeup for a game rained out in Kansas City. The last time the Angels played a doubleheader due to a rainout at Angel Stadium was Aug. 5, 1988. ... The Angels called up RHP Cory Rasmus for Game 2 of the doubleheader. By rule, teams are allowed to call up a 26th player for the second game. The Red Sox's 26th player for Game 2 was scheduled starter RHP Steven Wright. ... Red Sox C Blake Swihart was activated from the disabled list, and C Sandy Leon was designated for assignment. Red Sox manager John Farrell cited the need for more offense from the catcher's spot as the reason for the move.
