Young and Wieters each drove in three runs, and Jones delivered one of the Orioles' four doubles at a half-empty Yankee Stadium.
Everyone in Baltimore's starting lineup got a hit and scored a run. The Orioles posted their second-highest hit total in the Bronx, eclipsed only by a 22-hit outburst in 1986.
By the late innings, the game took on a spring training feel. The Yankees pulled several starters and the often-demanding crowd didn't even bother to boo while the Birds ran around the bases.
There was a big cheer, however, when two fans sprinted onto the grass and were tackled in the outfield by a wave of security personnel.
Wei-Yin Chen (1-1) weathered five innings for the win, giving up four runs and nine hits.
Ivan Nova (1-1) was tagged for seven runs and 10 hits in 3 2-3 innings.
For all the big hits, it was a little grounder that helped things get out of hand at the start.
After Nick Markakis led off the game with a single, Young followed with a bouncer up the middle. Many shortstops in the majors could've turned it into a double play, but 39-year-old Derek Jeter couldn't quite get to it and the ball skipped under his glove for a single.
Chris Davis followed with a sacrifice fly, and Jones hit his first homer of the season for a 3-0 lead. The Orioles chased Nova with a three-run fourth that made it 7-1 and added four more in the sixth.
Alfonso Soriano and Kelly Johnson hit solo home runs for the Yankees. Rookie Yangervis Solarte struck again, too, with a pair of doubles - he's hit safely in his first six career starts and is 11 for 24 overall with six doubles.
Young was 1 for 6 this season before manager Buck Showalter gave him this start. The designated hitter had an RBI single in the fourth that finished Nova and added his first homer, a two-run drive in the sixth. Wieters connected in the eighth.
Ryan Flaherty also had three hits for the Orioles after starting the year in a 1-for-21 rut. One of his hits was an early bunt single when Francisco Cervelli, a catcher making his first pro appearance at first base, ranged too far wide and in to field the ball.
NOTES: Carlos Beltran's RBI double marked the first run permitted by Baltimore in the first inning this season. ... Nova had allowed four or fewer earned runs in 24 straight starts since September 2012. That was tied with Hiroki Kuroda for the longest such string by a Yankees pitcher since Ron Guidry's 27-game streak ended in 1982. ... With David Robertson on the disabled list, Yankees manager Joe Girardi said RHP Shawn Kelley will likely be the closer. ... Orioles SS J.J. Hardy was out of the starting lineup for the third game in a row because of back spasms. ... Soriano hit his 407th career home run. ... RHP Masahiro Tanaka (1-0) starts the series finale Wednesday night in his Yankee Stadium debut vs. RHP Miguel Gonzalez (0-1).
