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

FINALE IN TORONTO

More from FoxSports

The first-place Blue Jays host the Yankees in the rubber game of their AL East showdown. Struggling right-hander Ivan Nova (6-8), recently removed from the rotation, steps back in to start for New York in place of injured Masahiro Tanaka. On the mound for Toronto is Marcus Stroman, who has won both his outings this season since returning from a knee injury - including one at Yankee Stadium. Toronto holds a 2 1/2-game lead over the Yankees.

ZACK ATTACK

As the Dodgers look to close in on the NL West title, Zack Greinke (18-3) tries to lower his major league-leading ERA of 1.65 when he pitches at home against the Diamondbacks. Greinke is in a remarkable race for the NL Cy Young Award with teammate Clayton Kershaw and Cubs ace Jake Arrieta, who improved to 20-6 with a 1.88 ERA by shutting out Milwaukee on Tuesday night.

SIDELINED STAR

Orioles manager Buck Showalter was unsure if center fielder Adam Jones will play against Washington. Jones sat out Tuesday night with a bad back and was not in the lineup Monday before that game was postponed because of rain. Showalter said Jones is improving but would not say he might return.

CLOSING TIME

Two teams in the AL Central are testing new plans for the ninth inning. With closer Greg Holland nursing a sore elbow, the first-place Royals have switched to Wade Davis for the rest of the season and the playoffs. And in Detroit, struggling closer Bruce Rondon was sent home for the remainder of the year. Tigers manager Brad Ausmus gave very little explanation, saying only that Rondon had been jettisoned because of his ''effort level.'' Detroit turned to Neftali Feliz in the ninth inning Tuesday night, and he blew a save opportunity after giving up the first hit of the game by the White Sox.

SWEET 17

Rangers right-hander Colby Lewis (16-8), looking to extend his career high for wins, tries to become the first 17-game winner for Texas since Scott Feldman in 2009 when he faces his former team in Oakland. Lewis also looks to win his third straight start for the AL West leaders. Athletics lefty Felix Doubront (2-1) is 0-5 with a 12.68 ERA and .427 opponents' batting average vs. Texas - his most losses against any team.
