A number of aces take the mound for their respective clubs with postseason races heating up as part of an action-packed slate of games streaming live on MLB.TV.
The Indians' Corey Kluber and the Nationals' Max Scherzer return to the hill after the Red Sox and Yankees battle in the Bronx.
Yu Darvish also starts for the Dodgers before a handful of division rivals go head to head throughout the day. The Royals and Twins are set to square off at Target Field, the Angels and Rangers meet at Globe Life Park in Arlington and the D-backs and Rockies clash at Coors Field, highlighting what has the looks of one of the most compelling slates of the season.
With a whopping 17 baseball games to be played in a single day -- thanks to doubleheaders between the Mets and Astros as well as the Dodgers and Padres -- there should be no shortage of excitement from early afternoon well into the night.

Here's what to watch for throughout the day (all times in ET):
Putting a "K" in Kluber: CLE@DET, 6:10 p.m.
Only Boston's Chris Sale (13.4 K/9) and Tampa Bay's Chris Archer (12.5 K/9) have struck out batters at a higher rate than Kluber (12.3 K/9) since the All-Star break, and few have been as impressive overall.
Having struck out 92 batters in 67 1/3 innings since the Midsummer Classic, the Cleveland right-hander is a legitimate challenger to Sale for the AL Cy Young Award, which he earned once already in 2014.
This evening he takes on the Tigers and right-hander Jordan Zimmermann, who is coming off a win over the Rockies in his previous outing.
Wild (Card) West: ARI@COL, 8:10 p.m.
Division rivals trying to maintain a hold on their position in the National League Wild Card standings face off when the D-backs send left-hander Patrick Corbin to the hill versus righty Jon Gray and the Rockies.
Corbin has been lights-out in stringing together four consecutive victories, allowing just one run in 30 1/3 frames over that span. The left-hander also has struck out 29 while holding opposing batters to a .171 average over those four outings.
Gray has been on a nice little run of his own, going 3-1 with a 2.30 ERA in five August starts.
To the Max: WAS@MIL, 7:10 p.m.
Mad Max is back, and that's a fantastic thing for baseball fans everywhere. Scherzer returned from a two-week DL stint to fire seven innings of one-run ball while striking out 10 Marlins.
He made fearsome Marlins outfielder Giancarlo Stanton look pedestrian, too, fanning him twice and inducing a double-play grounder in the slugger's other at-bat.
Tonight, Scherzer toes the rubber against the Brewers and 24-year-old Brandon Woodruff, who is 1-1 with a 1.62 ERA in his first three career starts as a big leaguer.
Yu can't touch this: LAD@SD, 10:10 p.m.
Darvish suffered his first loss as a member of the Dodgers his last time out, giving up three earned runs in five innings while striking out seven. Los Angeles went on to lose the game to Milwaukee, 3-2, but it was not a bad effort from the veteran hurler, who is now 2-1 with a 3.13 ERA while wearing Dodger blue.
Darvish will attempt to get back in the win column versus the Padres, who turn to right-hander Jhoulys Chacin as he looks to earn his first win since Aug. 1.
