Of course, Detroit's run ended in the World Series, as it was swept in four games by the San Francisco Giants.
Oakland may have been content with just making the playoffs last season, but it's a different story this year for the A's, who enter the postseason with perhaps the most complete team on the American League side.
"We were just riding that emotion and certainly happy to be where we were," Oakland manager Bob Melvin said. "But the mindset was different this spring; the expectations were different."
Last year, of course, the Athletics needed to win their final six games - including a three-game sweep of the Texas Rangers to close the regular season - to claim their first American League West title since 2006.
Well, Oakland proved that last year was no fluke, as it has spent most of the season at or near the top of the division. And thanks to another September swoon from Texas, it ran away with its second straight division title and finished the year 96-66.
This A's lineup resembles more of the late 80's power teams in Oakland at the plate without the star power of a Jose Canseco or Mark McGwire, of course, as these A's are led by a cast of virtual unknowns, including MVP candidate Josh Donaldson.
Oakland's 186 homers were the third best in baseball, but the team managed to hit at just a .254 clip, while striking out 1,178 times.
Donaldson hit .301 this season for the A's with 24 home runs and 93 RBI. He was even better down the stretch and earned the AL Player of the Month Award for September, as he hit .337 with eight doubles, five home runs and 16 RBIs in 25 games.
Still, you probably couldn't pick him out of a lineup.
"I'm a guy who's been downplayed my entire career," Donaldson said. "Even when I was a first-round draft pick (in 2007), I took 10 percent less than the guy before me. I just want something fair, something that's justified."
One concern the A's have heading into the postseason is the ailing shoulder of slugger Yoenis Cespedes. When he was in the lineup this season the A's were 83-51 compared to the 13-15 they were when he was out.
As a rookie last October, Cespedes batted .316 (6-for-19) with two RBI in five games during the ALDS.
The A's pitching staff was fronted by former AL Cy Young Award winner Bartolo Colon, who turned back the clock to win 18 games and post a 2.65 ERA, second only in the AL to the Tigers' Anibal Sanchez (2.57).
Colon, of course, did not pitch in last year's ALDS, as he was serving a 50- game ban for testing positive for performance-enhancing drugs.
Jarrod Parker also had a tremendous season for Melvin's crew, as he went a team-record 19 straight starts without a loss and ended the year 12-8 with a 3.97 ERA.
After those two Melvin has a few young arms at his disposal in righties A.J. Griffin (14-10, 3.83), Dan Straily (10-8, 3.96) and Sonny Gray (5-3, 2.67).
Oakland's bullpen has been a strength all season, but closer Grant Balfour and right-handed setup man Ryan Cook struggled late in the year. Still, Balfour saved 38 games in 41 chances. Lefty Sean Doolittle is also as good as it gets in helping set the bridge.
Detroit, meanwhile, had no hangover from its trip to the Fall Classic, as it went 93-69 to win a third straight AL Central crown thanks to another amazing campaign from Miguel Cabrera, and despite a wildly inconsistent season from ace Justin Verlander.
While Verlander struggled, the rest of the staff thrived, specifically right- hander Max Scherzer, who enjoyed the best year of his career, as he won an MLB-best 21 games, while pitching to a 2.90 ERA and striking out 240 batters over a career-high 214 innings.
