The closest division race moved the Pulse of the Postseason meter. The Tigers let a ninth-inning lead get away in Minnesota, but they maintained their 1 1/2-game AL Central lead when the Royals also were unable to hold a lead against the White Sox. Carlos Gomez and Hector Gomez manufactured the decisive run in the 12th inning of the Brewers' 3-2 victory in St. Louis, shaving the Cards' NL Central lead to 2 1/2 games over the Pirates and four over the Brew Crew.
With a 2-1 decision in Arizona behind Jake Peavy coupled with the Dodgers' 10-4 loss at Colorado, the Giants moved back within three games of Los Angeles' NL West lead. The A's and Royals in the AL and Giants and Pirates in the NL retained their Wild Card edges.
It was a big day in Atlanta before the Nationals celebrated with the groundbreaking of SunTrust Stadium, due for its unveiling in the 2017 season. Major League Baseball Commissioner-elect Rob Manfred and legendary Braves Hall of Famer Hank Aaron were on hand along with Braves CEO and chairman Terry McGuirk for the festive occasion.
And then there was Bryan Cranston's one-man show about postseason baseball on TBS, a hilarious creation featuring a guest appearance by Pedro Martinez. Everything is breaking right, not bad, for Cranston in this Super Tuesday performance.

The stars for the Orioles on clinching night fittingly were role players Steve Pearce, Alejandro De Aza and Jimmy Paredes, along with Ubaldo Jimenez in his first start since Aug. 16. Pearce got it rolling with a three-run homer in the first, Paredes hit as solo shot in the second and De Aza's three-run triple in the seventh broke it open. Jimenez held the Jays to two runs across five innings before turning it over to the superb Baltimore bullpen.
"They were in it two years ago," Blue Jays manager John Gibbons said of the Orioles. "When you look at their team, it's a solid ballclub. Solid pitching, all-around players, they have gritty hard-nosed type players."
Tanner Roark's seven shutout innings and Ian Desmond's two-run homer, his 23rd, carried the Nats to their second division title in three years in a 3-0 decision over the struggling Braves.
"It's has been amazing road, and now we are the NL East champs," Roark said. "It's nothing I have ever fathomed. We played hard and we won. That's the type of team that we have."
In Minnesota, the Tigers' J.D. Martinez unloaded a dramatic two-out, three-run homer in the top of the ninth off Twins closer Glen Perkins for a one-run lead. But embattled Detroit closer Joe Nathan and his defense watched it slip away. The Twins scored twice in the home half, a miscalculation by center fielder Ezequiel Carrera on Kurt Suzuki's line drive creating a game-tying double before Aaron Hicks' infield hit won it, breaking hearts in the Motor City.
At home, the Royals were unable to capitalize on their good fortune courtesy of the Twins against their former closer, Nathan. The White Sox broke through against Kansas City's gold-plated setup duo of Kelvin Herrera and Wade Davis for a late victory.
Atlanta fell 5 1/2 games off the pace for the second NL Wild Card, held by the Pirates by 1 1/2 games over the Brewers. The Giants hold the first Wild Card, leading the Pirates by 2 1/2 games. Buster Posey continued his hot streak with a homer and Brandon Crawford drove in the decisive run in support of Peavy, who was brilliant again in holding the D-backs to one run across 7 2/3 innings.
In St. Louis, the NL Central plot thickened as the Brewers rallied to get even with a run in the ninth against Cards closer Trevor Rosenthal and won it in the 12th when Carlos Gomez walked, stole second and third and scored on Hector Gomez's two-out single off Kevin Siegrist. Francisco Rodriguez locked it down for his 42nd save.
The A's had a chance to strengthen their grip on the Wild Card but were frustrated by the Rangers, 6-3, in Oakland. Pounding the Angels 13-2 in Anaheim, the Mariners edged within one game of the Royals and two of the A's in the Wild Card chase. The Indians and Jays are five behind the Royals, the Yankees six back.
