The Cubs’ Jake Arrieta throws a one-hitter in shutting out the Reds, 7 – 0. Brandon Phillips’ two-out double in the 8th is the only blemish as Arrieta strikes out 13.

Two more teams punch their tickets to the postseason. The Orioles are the AL East champions for the first time since 1997 after defeating the Blue Jays, 8 – 2, and the Nationals clinch the NL East crown for the second time in three years when they beat the Atlanta Braves, 3 – 0.

The Angels are the first team to clinch a postseason spot, securing at least a wild card berth after an 8 – 1 win over the Seattle Mariners. Rookie Matt Shoemaker wins his 16th of the year with another outstanding performance, but has to leave the game in the 8th with an apparent injury.

The Mets’ Jacob deGrom ties a major league record when he strikes out the first eight batters he faces before his opponent on the mound for the Marlins, Jarred Cosart, singles to right. DeGrom ties the record set by Jim Deshaies in 1986. He strikes out 13 in 7 innings but ends up with a no-decision as the Marlins win, 6 – 5.

With Cub runners on first and second in the fourth inning of the team’s 7-3 victory over Chicago, the Pirates turn an 5-4-3 around-the-horn triple play when third baseman Josh Harrison fields Matt Szczur’s hard grounder, stepping on the bag to force Chris Valaika before firing the ball to second to Neil Walker to retire Mike Ott. The second baseman’s relay to first sacker Andrew Lambo completes the first triple killing in the 14-year history of PNC Park.

The Marlins win their first game since losing star OF Giancarlo Stanton to an injury thanks to a dramatic 9th-inning comeback against the Phillies. Trailing 4 – 1, the Marlins score four times against closer Jonathan Papelbon as Jordany Valdespin, Christian Yelich and Justin Bour collect RBIs to tie the score, and a wild pitch by Papelbon lets in the winning run. A frustrated Papelbon then gets ejected by umpire Joe West for gesturing at the crowd before Steve Cishek pitches the bottom of the inning to rack up his 35th save, setting a new personal best. Papelbon will be fined and suspended seven games for his unprofessional gesture, but umpire West will also receive a one-game suspension for grabbing the pitcher’s jersey after the incident.

2014 – The Dodgers crush the Giants, 17 – 0, setting a record for most runs by a visiting team at AT&T Park. The Dodgers’ 24 hits are the most by any team at the ballpark. Zack Greinkepitches 6 scoreless innings and adds a double and homer, while Hanley Ramirez has four hits and Matt Kemp goes 3 for 3.

The Orioles move closer to clinching the AL East title with a doubleheader sweep of the Yankees, 2 – 1 and 5 – 0. But they also get bad news as slugger Chris Davis is handed a 25-game suspension for testing positive for amphetamines.

Alex Cobb of the Rays makes a bid for a no-hitter against the Yankees, keeping them hitless until Chris Young doubles with one out and New York trailing 4 – 0 in the 8th. Pinch-hitter Martin Prado follows with a pinch homer off reliever Brad Boxberger that cuts the lead in half. Not content with having spoiled Cobb’s big night, Young then hits a walk-off three-run homer off Jake McGee in the 9th to give the Yanks a 5 – 4 win.

Giancarlo Stanton is hit in the face by a ball thrown by the Brewers’ Mike Fiers in the 5th inning. The Marlins’ best player suffers multiple facial fractures and broken teeth after lying motionless at home plate, bleeding profusely, for several minutes after the beaning and is carried away on a stretcher. Stanton was swinging on the pitch, so it is called a strike; pinch-hitter Reed Johnson completes the at-bat, and strikes out on a pitch that hits him on the hand, prompting both benches to clear. Marlins manager Mike Redmond and 3B Casey McGehee are both ejected for arguing umpire D.J. Reyburn’s decision to call both pitches strikes. In the 6th, Miami pitcher Anthony DeSclafani is also thumbed, for hitting Carlos Gomez on the left elbow in a gesture that is seen as retaliation; bench coach Rob Leary also gets the heave-ho since he is now the acting manager and both benches had been warned. For his part, Fiers leaves the game after striking out Johnson and issues an immediate emotional apology, denying any intention to hit Stanton. Incidentally, the Brewers win the game, 4 – 2.
