Chris Sale pitched five dominant innings as the Red Sox beat the Orioles Sunday at Fenway Park and extended its franchise-best start to 13-2.

Sale allowed two hits and a run while striking out eight in the Red Sox 3-1 victory over the Orioles.

The 29-year-old lefty threw 93 pitches, 56 of them for strikes.

Andrew Benintendi tied the game at 1 in the fifth with an RBI triple into the corner in right, scoring Jackie Bradley Jr.

The go-ahead run came in the sixth, when J.D. Martinez scored from third on a wild pitch that skipped away from catcher Caleb Joseph.

The Sox added another run in the sixth on a ground-rule double to right field by Tzu-Wei Lin.

Craig Kimbrel pitched a 1-2-3 ninth for his fifth save in as many opportunities.

The game-time temperature of 34 degrees marked the coldest game at Fenway since April 17, 2003, when the Red Sox hosted the Rays.

The last team to begin a season by winning 13 of its first 15 was the 2013 Braves.
