Mountcastle and Hays homer in Orioles' victory over Blue Jays

TORONTO — The Baltimore Orioles took advantage of an uneven pitching performance by Toronto starter Yusei Kikuchi in a 6-5 win over the Blue Jays on Tuesday at Rogers Centre.

Ryan Mountcastle hit a two-run homer in the third inning and Austin Hays added a solo shot in the fifth that ended the Toronto southpaw's night. Kikuchi (2-3) walked four batters and allowed five hits.

Toronto third baseman Matt Chapman homered and scored twice while rookie catcher Gabriel Moreno had three hits and drove in two runs.

It was Baltimore's first win over Toronto (36-25) in eight meetings and the Blue Jays' fifth loss in 19 games overall.

Moreno drove in Santiago Espinal with a one-out single in the eighth inning to make it a one-run game. Baltimore's Jorge Lopez got the last five outs for his ninth save.

Mountcastle opened the scoring by turning on a 1-0 pitch from Kikuchi for his 10th home run of the year. The Baltimore first baseman had three hits on the evening.

Chapman, who missed Toronto's last three games with a sore wrist, singled off Baltimore starter Jordan Lyles (4-5) in the third inning and scored when Bo Bichette hit a slow chopper with the bases loaded.

Baltimore (27-36) tacked on another run in the fourth but Chapman tied the game in the bottom half of the inning with a two-run shot for his eighth homer of the season.

After Hays opened the fifth with his eighth homer of the season, reliever Trevor Richards gave up another run on a Tyler Nevin sacrifice fly that plated Mountcastle, who reached on a ground-rule double.

Mateo made it 6-3 on a Cedric Mullins RBI single in the sixth inning. Trent Thornton came on in relief and got Hays to hit into an inning-ending double play.
