BALTIMORE (AP) Rick Porcello pitched a four-hitter for his major league-high 21st victory, David Ortiz and Mookie Betts hit two-run homers and the Boston Red Sox beat the Baltimore Orioles 5-2 on Monday night to pad their lead in the AL East.

Coming off a four-game sweep of the Yankees, Boston sustained its late-season surge in the opener of an important four-game series for both clubs. The Red Sox stand atop the division by a season-high four games.

Adam Jones homered and Mark Trumbo picked up his 102nd RBI for the second-place Orioles, who started the day with a one-game lead over Toronto for the top AL wild card.

Porcello (21-4) struck out seven and walked none in his third complete game of the year. Five days earlier against Baltimore, the right-hander gave up one run in eight innings but took the loss.
