In the Central, the Royals lost the completion of a suspended game but bounced back to beat the Indians in the second game and now trail the Tigers by a game in the division standings. Out West, the Giants outlasted the Dodgers in 13 innings to cut Los Angeles' division lead to 3 1/2 games. And in the AL East, the Orioles, who'd already clinched the division, wrapped up home-field advantage in their AL Division Series even though they were blanked, 5-0, by the Yankees, simply because Detroit lost to the White Sox.

Leave it to Wainwright to get the Cardinals where they want to be. The St. Louis ace was at it again on Monday, blanking the Cubs for seven innings as the Cardinals got even closer to a division title.
Pittsburgh isn't giving up, though. In fact, the Pirates seem to be playing their best baseball of the year, and a lot of it comes down to the fact that their pitching has been superb at the most important time of the year. This was proven once again in a 1-0 win over Atlanta on Monday night that featured a sixth-inning home run by Andrew McCutchen and nothing else but a dominant effort from starter Francisco Liriano and the bullpen.
"Pitching's been pretty good around here," McCutchen said. "One run, and the way Liriano is throwing, and the bullpen's been lights-out."
Now Pittsburgh can secure a Wild Card spot Tuesday with a victory and a Milwaukee loss. If the Pirates finish the regular season with the same record as the Giants (both clubs are 85-71 going into Tuesday), they will host that game at PNC Park by virtue of their 4-2 record vs. the Giants this year.
Another team paying a lot of attention to math this time of year is the Orioles, who would like to catch the Angels for best record in the AL, but realize that this might not be the best bet with a 2 1/2-game deficit in that department with six to play. Then again, Detroit's loss on Monday made sure that Baltimore will begin its Division Series at Camden Yards.
"It is [nice], and it wasn't a foregone conclusion," Orioles manager Buck Showalter said of guaranteeing at least two playoff games in Baltimore. "I keep saying you are not paranoid, you are alert to things. It could happen. You never assume anything."
The Tigers and Royals certainly can't assume anything at this stage of the game. Entering Tuesday, the Royals are a mere game behind the Tigers for the division title, and the math isn't difficult to decipher.
And with the Mariners losing to Toronto and falling two games back of Kansas City, the Royals are looking good once again for a Wild Card spot at the very least. The A's, too, have to like their October chances once again after beating the Angels on Monday to stay in the No. 1 slot in the AL Wild Card running.
On Tuesday, in addition to the Pirates and Giants possibly clinching postseason berths, the Mariners will rely on their ace, Felix Hernandez to try to keep them afloat in the AL Wild Card race.

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.
