Postseason Picture for Tuesday, Sept. 9

Postseason Picture for Tuesday, Sept. 9

Another September day is over, and more teams are on the move in pennant races that are getting closer and more dramatic by the minute as the Pulse of the Postseason quickens. On Monday, the week began with the Detroit Tigers getting closer to the Kansas City Royals in the American League Central standings, the Seattle Mariners getting closer to the Oakland A's in the AL Wild Card standings, and the Pittsburgh Pirates continuing to pull away from the Milwaukee Brewers in the NL Wild Card race.

Meanwhile, the most dominant teams in the Majors continued to exert their strength. The Angels kept pounding the baseball in a win over Cleveland, and the Washington Nationals, Baltimore Orioles and St. Louis Cardinals did what they had to do on what right now looks like a procession to the postseason.

Postseason picture

The AL Central has been one of the more intriguing divisions for the last few months, and it lived up to that billing on Monday, when the second-place Tigers opened up a crucial three-game series against the first-place Royals with a 9-5 win. With the victory, the math became easy: Detroit can tie up the Central with a win on Tuesday.

In the NL Central, the Cardinals held serve and their 4 1/2-game lead with a 5-0 win over the Reds, and the Pirates won their fourth straight game to continue to solidify their position in the Wild Card's second spot, especially after Milwaukee lost to Miami for its third consecutive defeat.

"To try and pay attention to it would be chaotic," Pirates manager Clint Hurdle said. "We need to play our best ball, we need to focus on the game we're playing. If we play our best ball for the 19 remaining games, we'll get in."

Out West, the Mariners were in the middle of their tight game against the Astros when they had to notice up on the out-of-town scoreboard that the A's had lost to the White Sox in the 12th inning in the Windy City. Seattle responded with a 4-1 win over Houston and now sits a mere one game behind Oakland for the first spot in the AL Wild Card race while the Tigers are only a half-game behind the Mariners for the second slot.

The AL West division race looks more and more like a done deal with each Angels game these days. On Monday, they were relentless again, pounding the Indians, 12-3, to win their fifth in a row and improve the best record in MLB to 88-55.

Jered Weaver notched his 16th win to lead the AL in that category and the Angels got home runs from Albert Pujols, David Freese, Kole Calhoun and Howie Kendrick.

And the AL East and NL East saw much of the same again, with the Orioles and Nationals keeping up the winning ways and building on their sizable division leads. Baltimore now has 10 games on the second-place Yankees, and Washington, which beat Atlanta on Monday, has eight games on the Braves.

"It would be nice to win the division knowing that we can beat the Braves more than winning the division knowing that we can't beat the Braves," Nats reliever Craig Stammen said. "This proves we can play good baseball against a good team, and [it can] prepare us for a playoff-type atmosphere if we get to that point."

TODAY'S KEY GAMES TO WATCH (all times ET)

Braves (Santana, 14-7) at Nationals (Zimmermann, 10-5), 7:05 p.m. Preview

The Braves probably would be in a lot more trouble if they didn't sign Ervin Santana during Spring Training. They need him now more than they have all year.

Pirates (Volquez, 11-7) at Phillies (Buchanan, 6-7), 7:05 p.m. Preview

Edinson Volquez has been a pleasant surprise for Pittsburgh this year. The Pirates can keep their recent momentum rolling with a big start from the right-hander.

Royals (Vargas, 11-7) at Tigers (Scherzer, 15-5), 7:08 p.m. Preview

The Tigers can move back into a tie for the lead in the AL Central with a win here, and they have their best starter on the mound in Max Scherzer.

Cardinals (Wacha, 5-5) at Reds (Leake, 10-11), 7:10 p.m. Preview

The Reds are falling out of it, but the Cardinals are not, and they're very eager to see how Wacha is rebounding from shoulder woes, because they'd like for the young righty to be where he was at this stage last year.

Marlins (Koehler, 9-9) at Brewers (Garza, 7-8), 8:10 p.m. Preview

Milwaukee can't afford to lose many games the rest of the way, and they certainly can't afford to lose at home. They'll lean on a playoff-tested starter in Matt Garza.

A's (Lester, 13-10) at White Sox (Danks, 9-10), 8:10 p.m. Preview

The A's have been taking some heat for trading away their cleanup hitter, Yoenis Cespedes, to get Jon Lester. The southpaw can quiet some of that noise with a good start in a huge road game.

Astros (McHugh, 8-9) at Mariners (Elias, 10-12), 10:10 p.m. Preview

The Mariners are back home and need to take advantage of it as they try to keep or improve their position in the Wild Card race.

TIEBREAKER SCENARIOS

A tiebreaker game will be played to determine a division winner, even if the tied clubs are assured of participating in the postseason. If a division championship tiebreaker is necessary, the head-to-head record between the clubs will determine home-field advantage. If the head-to-head record is tied, then division record will be the next tiebreaker.

If two clubs are tied for the two Wild Card berths, home-field advantage will be determined by the head-to-head record between the clubs. If the head-to-head record is tied, then division record will be the next tiebreaker.
