A look at what's happening all around the majors today:
OCTOBER COMES EARLY
Reggie Jackson hitting three home runs, Don Larsen pitching a perfect game, Jackie Robinson sliding into Yogi Berra. Dodgers vs. Yankees always conjures up World Series memories. Matchups in the regular season? Not so much. Since interleague play began in 1997, the Dodgers have visited Yankee Stadium for just one day - they split a doubleheader in the Bronx in 2013. The NL West leaders open a three-game series against the AL playoff contenders, with Los Angeles rookie Jose De Leon starting against Bryan Mitchell.
BIRDS IN BEANTOWN
Red Sox lefty David Price tries for his seventh straight win when he faces Baltimore at Fenway Park in a game full of playoff implications. Boston leads the AL East while the Orioles and Toronto are tied two games back for the wild-card spots. Lefty Wade Miley starts for the O's.
The St. Louis Cardinals have activated All-Star shortstop Aledmys Diaz from the disabled list. He missed 36 games after his right thumb was broken when he was hit by a pitch. Diaz was batting a team-best .312 with 14 homers and 57 RBIs in 96 games when he got hurt. The wild-card contenders host the NL Central-leading Cubs.
Mat Latos makes his first start for the NL East-leading Nationals, facing the visiting Mets. The 28-year-old righty was 6-2 with a 4.62 ERA for the White Sox when they cut him in June. Latos has won once in relief for Washington. He was a top starter for the Reds a few years ago when they were managed by Dusty Baker, now the Nationals' skipper.
METS ON THE MEND
Mets lefty Steven Matz is set to throw again at the team's spring training complex in Florida as he rehabs from shoulder tightness. Teammate Jacob deGrom might toss off a mound as he recovers from soreness in his right forearm.
