A look at what's happening around the major leagues Wednesday:



The Pirates and Cubs continue a pivotal four-game series a day after a day-night doubleheader in Pittsburgh. The Bucs sit atop the NL wild-card standings. Chicago is within striking distance and St. Louis is narrowly ahead of both in the NL Central standings. Pirates right-hander A.J. Burnett (8-5, 3.14) makes his second start since returning from the DL following a strained right elbow, while Cubs righty Jake Arrieta (19-6, 1.99) hopes to help his late push for Cy Young Award consideration.


Mike Napoli will play left field again when the Rangers host the Astros in the third game of a pivotal AL West four-game series. Napoli played outfield for the first time as a pro Sunday against Oakland, and again Monday when he dropped a flyball in the Rangers' 5-3 win over Houston. Manager Jeff Banister said he's trying to use a right-handed bat to boost a lineup that has struggled at times against left-handers. Cy Young Award candidate LHP Dallas Keuchel (17-7, 2.22 ERA) is scheduled to start for Houston.


Matt Holliday has returned just in time to help the Cardinals make their final push for the NL Central crown. The seven-time All-Star was activated from the DL on Tuesday but was not in St. Louis' lineup after missing more than two months with a right quadriceps strain. LHP Jaime Garcia (8-5, 2.33) goes for St. Louis in the second game of a set with Milwaukee, who sends out RHP Wily Peralta (5-8, 4.14).


Rays RHP Chris Archer looks to get back to his winning ways against the Yankees. Archer (12-11, 2.95) dropped to 5-1 vs. the Yankees after losing in his last start against them Sept 6. He took a shutout into the sixth before allowing a three-run homer to Brian McCann and a solo shot to Alex Rodriguez. Rookie RHP Luis Severino (3-3, 3.35) will start for the Yankees.


Indians RHP Danny Salazar (12-8, 3.57) hopes to replicate his strong August results after a disappointing first couple of outings this month. Salazar has allowed nine runs in 10 innings over his last two starts. Cleveland faces Kansas City as a late addition to the AL wild-card race, while the Royals are limping to the finish but still have the AL's best record. Danny Duffy (7-7, 4.14) pitches for Kansas City.
