Tonight's rainouts affect clinch scenarios

Large amounts of rainfall approaching the East Coast has forced a number of postponements across baseball on Friday, with the Phillies, Orioles and Mets calling off their respective home games.

The Orioles-Yankees and Mets-Nationals games Friday night have been rescheduled as split-admission doubleheaders Saturday, and the Phillies-Marlins game from Friday night will be played as a single-admission doubleheader Saturday.

The Mets and Dodgers, who will meet in next week's National League Division Series, entered Friday with identical 89-70 records. Although home-field advantage for that NLDS hasn't yet been determined, the Mets hold the tiebreaker with L.A., having won four of the teams' seven meetings this season. The Dodgers were set to open a three-game series against the visiting Padres on Friday night.

The Yankees entered Friday with a three-game edge on the Astros for the top American League Wild Card spot. One Yankees win or Astros loss for the remainder of the regular season will assure the Yankees of hosting Tuesday's AL Wild Card Game presented by Budweiser.

The Phillies (62-97) and Reds (63-96) entered Friday with the two lowest winning percentages in the Majors, and the top pick in the 2016 Draft will go to the team that closes the season with the lowest winning percentage. Should more than one team finish the year tied for the lowest winning percentage, the team among those clubs with the lowest winning percentage at the end of the 2014 season will select first overall next June.

The first Orioles-Yankees game will be played at 12:05 p.m. ET. The nightcap will be at 7:05 p.m. ET. The first of tomorrow's Phillies-Marlins games will be played at 4:05 p.m. (gates open at 3:05 p.m.). The Mets-Nationals doubleheader Saturday is reportedly slated for 1 and 7 p.m.

Fans holding tickets to Friday's cancelled Phillies game may exchange them for Saturday's 4:05 p.m. doubleheader, Sunday's 3:05 p.m. season finale or any 2016 home game. Fans wishing to exchange their tickets for a '16 game may do so when single-game tickets go on sale in February. Exchanges for a '16 home game should occur by May 31, 2016.

Separate admission is required for each of the Orioles-Yankees games. Tickets for Friday's game will be honored for the 12:05 p.m. game Saturday, with gates opening at 10:30 a.m. and parking lots at 10 a.m. Gate times for the 7:05 p.m. game will be announced at the conclusion of the first game.

For the Orioles game, fans who are unable to attend the makeup game can exchange their tickets for any remaining home game this season on a "dollar-for-dollar" basis. StubHub tickets are also non-exchangeable, but may be resold on StubHub until 12:00 p.m. on Saturday. Prepaid parking permits dated for Friday are valid only for the 12:05 p.m. makeup game on Saturday.

Baltimore fans may also hold their tickets until 2016 tickets go on sale, at which point they may be exchanged for tickets to any April 2016 home game (except Opening Day). All exchanges are subject to availability and must be completed by April 30, 2016.
