First Oriole down the orange carpet: Danny Valencia, who as part of a three-player number swap took No. 2 from departed Orioles shortstop J.J. Hardy ahead of Opening Day.
First pitch, ceremonial: Former head athletic trainer Richie Bancells, who retired last fall after 41 years with the organization, threw to the longest-tenured Oriole, center fielder Adam Jones. After the pitch, the entire roster joined Bancells on the field for a photo as Jimmy Buffett's "Margaritaville" played on the stadium sound system.
First pitch, for real: Orioles right-hander Dylan Bundy had a 91 mph fastball fouled off by Twins second baseman Brian Dozier at 3:08 p.m. The game-time temperature was 65 degrees.
First hit: Orioles shortstop Manny Machado hit a first-pitch fastball off the right-field wall for a one-out double in the first inning, with an exit velocity of 108.6 mph, according to Statcast.
First Orioles-y moment at the plate: With Machado on second base, second baseman Jonathan Schoop worked the count to 3-0 against Twins starter Jake Odorizzi before swinging through three letter-high fastballs and striking out.
First wow moment: Everyone gets cheered on Opening Day, but surprise starting right fielder Craig Gentry earned his in the second inning. After Eddie Rosario smoked a pitch to right-center field, Gentry leaped at the wall and pulled the ball from the top of the groundskeeper shed.
First strikeout: After five loud flyouts, Bundy froze shortstop Eduardo Escobar on a front-door slider to end the second inning.
First stolen base: Machado reached base for a second time with two outs in the third inning, and swiped the team's first bag of the season to put himself into scoring position for Schoop. But Schoop grounded out to third base to end the inning.
First gem: Bundy pitched seven scoreless innings in his first start of the season, but settled for a no-decision.
First blown save: Brad Brach made 34 pitches and allowed two runs in the ninth to let the Twins force extra innings with the game tied at 2.
