Instead, the Orioles were left to begin their first playoff appearance in 15 years on the road against two-time defending league champion Texas.
Longoria homered three times and the Tampa Bay Rays shut down the Orioles 4-1 Wednesday night at Tropicana Field, where Longoria also ended last season with a bang.
Baltimore began the day one game behind the New York Yankees in the division. The Orioles needed a win, plus a loss by the Yankees to Boston, to pull even.
New York cruised to a 14-2 rout of the Red Sox and finished two games ahead of the Orioles, earning its 13th division crown in 17 years. The Yankees had a 10-game lead on July 18 but Baltimore caught up Sept. 4 and the teams were tied 10 times in September.
"We knew it was a long shot, but we ran into some really good pitching," Orioles manager Buck Showalter said. "I've got to tip my hat to them, and what is really kind of amazing is that you look over there with what they've been able to do this year, win 90 games, and that tells you what a fine line there is in all those extra-inning games and one-run losses, and we could be in the same position they are."
The loss sent the Orioles to Texas, where they'll play the Rangers on Friday night, with the winner advancing to the best-of-five division series against the New York Yankees.
"We're going to take it one game at a time. Obviously if you lose, you're done," said Orioles slugger Chris Davis, who had homered in six straight games. "We're going to try to do everything we can to beat Texas and get back home."
Longoria finished the season in dramatic fashion for the second straight year, hitting solo shots off Chris Tillman in the first and fourth innings and adding another solo drive off Jake Arrieta in the sixth.
With a chance to tie the major league record of four homers in a game, the three-time All-Star who missed 85 games this year with a strained left hamstring grounded out in the eighth.
"It was cool," Longoria said. "That's about as fun a night as you can have in a ballgame."
Longoria's second career three-homer game came a year after he hit two of them of the final night of last season, including a 12th-inning, game-ending shot that clinched a post-season berth. The area beyond a short wall in the left-field corner where the biggest homer in franchise history landed is now called 162 Landing.
"I just think it highlights how well we play in games 162," Rays manager Joe Maddon said. "It was a very dramatic game, the way it all unfolded. I just like the idea that we played the last game of the season with that kind of effort and intensity."
Ryan Roberts also homered for the Rays in the fourth against Tillman (9-3).
Jeremy Hellickson (10-11) allowed one hit — Adam Jones' fourth-inning single — in 5 1-3 innings. Jake McGee, Wade Davis, Joel Peralta and Fernando Rodney teamed up to hold the Orioles to two hits — J.J. Hardy's double and Matt Wieters' single, both in the ninth inning — the rest of the way.
Jones ruined Tampa Bay's shot at a 16th shutout with a sacrifice fly off Peralta. After Wieters singled, Rodney was summoned to get the final out for his 48th save in 50 opportunities.
Davis, who tied an Orioles record when he homered for the sixth straight game in a 1-0 win over Tampa Bay on Tuesday night, went 0 for 4 with three strikeouts.
Baltimore had five hits in the final two games of the regular season, but Jones is confident the offence will bounce back for the club's first post-season game since 1997.
"We ain't got no choice. You don't hit, you go home," Jones said. "It's no ifs, buts or maybes. Both teams know that."
Longoria has homered in five of his last seven plate appearances in the final game of the season. In four career Game 162s, he is 8 for 15 with six homers and nine RBIs.
"Sometimes you've got to give credit where credit is due. He put some good swings on some pitches, but I should have been better," Tillman said. "I knew what I needed to do. I just didn't get it done."
Longoria is 6 for 12 with three homers against Tillman, who lasted five innings and allowed three runs on four hits in his first loss since Kansas City beat him on Aug. 11. The right-hander who had gone 3-0 with a 1.20 ERA over his previous five starts also allowed three homers in that game, matching his career high.
The Rays (90-72) won 12 of 14 down the stretch, remaining in contention for the second AL wild card until the 160th game and finished with at least 90 wins for the third straight season.
Hellickson allowed three baserunners, two of them in the fourth inning when Jones singled to right-centre after Davis struck out on a wild pitch that allowed him to reach first. The 2011 AL Rookie of the Year walked Manny Machado leading off the sixth and was replaced by McGee after getting the next batter, Nate McLouth, to pop out.
"The big tip of the cap goes to Joe Maddon and the Rays. They played 162," Jones said. "Their players went out every game to the last one and gave it all they've got."
NOTES: Jones played in every regular-season game this season. "It's a pretty cool thing," Showalter said. Jones is the first Baltimore player to accomplish the feat since Miguel Tejada in 2006. ... Orioles RHP Steve Johnson (sore left knee) said he felt great after throwing off a bullpen mound. ... Rays CF B.J. Upton, who can become a free agent this winter, singled in what might have been his last at-bat with Tampa Bay. The crowd of 17,909 gave him a standing ovation when he was removed for a pinch-runner in the eighth inning.
