Mark Trumbo with a walk-off homer as O's win in 11th

Yes, there were similarities to the American League wild card game. The Orioles and Toronto, tied 2-2, playing in extra innings.

But a different team won in 11 innings this time. Mark Trumbo, who didn't homer once in spring training, blasted a shot to left on a 1-2 pitch from Jason Grilli, and the Orioles beat Toronto 3-2.

This was the sixth career walk-off homer for Trumbo, who led the majors with 47 home runs in 2016.

This was the ninth extra-inning Orioles opening day game, and the first since 2003. The Orioles have now won seven straight opening day games, 14 of the last 17 and are 42-22 all-time in season openers.

After the Orioles went 0-for-5 with runners in scoring position their first two innings, they scored twice in the last of the third to take the lead.

Right fielder Seth Smith led off with his first O's hit. He drove a double to deep center off Marco Estrada, and Adam Jones walked on four pitches. After Manny Machado's flyout, Chris Davis was off-balance as he offered at a changeup. With basically a one-handed swing, he singled off the right field wall for a 1-0 lead. He was thrown out trying for a double. Batting next, Trumbo hit a high fly along the right field line that dropped in for an RBI double and 2-0 lead.

In the top of the fifth, O's starter Kevin Gausman lost the strike zone, but at least he didn't lose the lead. He allowed three walks in the inning - one with the bases loaded - as Toronto pulled within 2-1. Gausman threw 35 pitches in the inning, but issued just one single. Kendrys Morales' bases-loaded base on balls got the Blue Jays on the board. But Gausman got Troy Tulowitzki to ground out, ending a nine-pitch at-bat to leave the bases loaded.

However, an inning later, the Blue Jays tied the game, with the run charged to Gausman after he had left the contest. He allowed a one-out single to Steve Pearce and Mychal Givens came on. After a flyout, Ezequiel Carrera's double down the right field line tied it 2-2.

Gausman, in his first opening start, got a no-decision. He went 5 1/3 innings, allowing five hits and two runs with four walks and four strikeouts. He issued more than three walks just once last season.

Estrada also got a no-decision, although he finished his outing by retiring the last 10 Orioles he faced. Over six innings, the right-hander gave up five hits and two runs with two walks and four strikeouts. He threw 89 pitches, 63 for strikes.

On Wednesday night, Dylan Bundy faces left-hander J.A. Happ to wrap up this two-game series.
