Orioles score six in 10th to cruise past Red Sox

Gunnar Henderson and Colton Cowser each homered during the six-run 10th inning that lifted the Baltimore Orioles to a 9-4 win over the host Boston Red Sox on Thursday night.

Cowser went 3-for-5 with two homers, a double, four RBIs and two runs scored. The Orioles hit four homers during their nine-hit attack. He drove in 10 runs in the three-game series sweep.

Henderson and Anthony Santander also drove in two runs apiece.

Jarren Duran and Wilyer Abreu each had two hits and an RBI for the Red Sox.

In the eighth inning with Boston clinging to a 2-1 lead, Red Sox shortstop David Hamilton missed touching second on a would-be double-play grounder by Adley Rutschman. The Orioles took advantage of the miscue as Santander hit a two-run, go-ahead homer down the right-field line.

Pinch-hitter Connor Wong hit a game-tying, two-out homer to deep left-center off Danny Coulombe in the bottom of the eighth.

Boston closer Kenley Jansen retired the final two batters in the ninth and Baltimore counterpart Craig Kimbrel (2-0) threw a scoreless ninth to force extra innings.

Henderson hit a two-run shot off Red Sox reliever Isaiah Campbell (0-1) to give the Orioles a 5-3 lead. Campbell retired the next two batters, but Ryan O’Hearn hit a double and Ryan Mountcastle walked. Cedric Mullins followed with an RBI single to center and Cowser cleared the bases with a three-run shot to center to give Baltimore a 9-3 lead.

Duran got Boston a run back on a leadoff double in the last of the 10th.
