BALTIMORE -- Ubaldo Jimenez pitched seven innings of one-hit ball, Jonathan Schoop hit his first career grand slam and the Baltimore Orioles defeated the Toronto Blue Jays 7-1 on Saturday night.

Left fielder Alejandro De Aza and first baseman Chris Davis added first-inning homers for Baltimore.

Jimenez retired the first nine Blue Jays he faced before shortstop Jose Reyes led off the fourth inning with a line-drive single to left field. The only other Blue Jays base runner against Jimenez came when Reyes walked with two outs in the sixth.

The right hander struck out eight and walked one, throwing 96 pitches, including 61 for strikes.

Jimenez (1-0) struggled in 2014, his first season with Baltimore, going 6-9 with a 4.81 ERA in 22 starts and three relief appearances.

On Saturday night, he began his 2015 season by shutting down a Toronto offense that scored 12 runs on 16 hits in Friday's win.

Meanwhile, 22-year-old Aaron Sanchez, a first-round pick by the Blue Jays in the 2010 draft, made his first major league start after working as a reliever last season.

Sanchez (0-1) lasted 3 1/3 innings, allowing three runs, seven hits and two walks.

Davis went 2-for-3 and was hit by a pitch, and De Aza was 2-for-5 and scored twice.

Toronto averted the shutout when Edwin Encarnacion singled home Steve Tolleson, who had doubled, with two outs in the ninth.

Leading 3-0, Schoop and the Orioles broke it open in in the fifth off reliever Todd Redmond.

After a single by center fielder Adam Jones, and walks to designated hitter Travis Snider and third baseman Manny Machado -- in a 10-pitch at-bat -- Schoop smashed a 1-1 pitch to left for his first career grand slam.

Sanchez posted a 1.09 ERA in 24 relief appearances with the Blue Jays last season and didn't allow an earned run in his final 14 innings.

That streak ended abruptly when De Aza, the Orioles' leadoff hitter, sent a 1-0 fastball over the wall in right.

Two batters later, Davis deposited the right-hander's first pitch about 20 rows into the left-center field stands to make it 2-0.

The Orioles loaded the bases with three consecutive singles to open the third but were held to one run after Jones grounded into a 6-4-3 double play and Snider flied out.

Baltimore squandered another chance in the fourth, failing to score when an error, single and Sanchez wild pitch put runners on second and third with no outs.
