The Orioles' first game of the 2015 season started at 3:11 p.m. at Tropicana Field with a called strike from Tampa Bay pitcher Chris Archer to Orioles leadoff hitter Alejandro De Aza. It was called by home plate umpire Dana DeMuth.
De Aza had a few firsts as well. He was the Orioles first baserunner, reaching on a throwing error by Archer in the first inning. He then scored the first run of the Orioles' season on an RBI single to left by newcomer Travis Snider, which was the club's first hit of 2015.
De Aza also hit the Orioles' first home run of the season, a two-run shot off Archer in the top of the fifth, which made it 3-0.
Manny Machado had the first walk and Steve Pearce was the first Oriole to strike out – on a 96 mph fastball from Archer that caught Pearce looking. Both of those ocurred in the first inning.
Chris Tillman's first pitch was a ball to John Jaso. He walked Jaso and then picked up his first strikeout by fanning Steven Souza Jr.
The first replay review came in the bottom of the fifth inning when the Rays challenged that a catcher obstruction call was not made. The review lasted one minute, 28 seconds and the call was upheld.
Rays third baseman Evan Longoria hit the first home run allowed by an Orioles pitcher off Tillman in the seventh.
