With 1 day left in the regular season, the NL still has NY Mets, Philadelphia, Colorado and San Diego fighting for a playoff spot.
Arizona and Chicago are in.
If the Rockies beat the Diamondbacks again, and the Padres lose to the Brewers for the second straight day, the Rockies force themselves into tiebreaker action for the National League Wild Card berth.
***
there's a four-way tie among the Mets, Phillies, Rockies and Pads:
• The Mets and Phillies would play in Philly on Monday to crown the East champ.
• The loser would then enter a three-game mini-tournament for which the Rockies, based on head-to-head records during the regular season, would have the option of needing to win twice at home or once on the road to advance.
• If the Rockies choose to stay home, their opponent would be determined by the wishes of the team with the second-best combined head-to-head record; it'd be the Phillies if they're involved, but the Padres if the Mets drop into the three-way. That team could choose to play at the Rockies on Tuesday, but it's more likely that it would opt for a single game and travel to play the winner of Tuesday's game on Wednesday.
• If the Rockies opt for the one road game, Tuesday's game would feature New York at San Diego, or San Diego at Philly, with the winner hosting Colorado on Wednesday.
If there's a three-way tie among the Padres, Mets and Phillies: This scenario is possible only if the Padres and Rockies both lose Sunday and the Phillies and Mets both win.
• The Mets and Phillies would play in Philly on Monday to crown the East champ.
• Monday's losing team would play Tuesday to decide the Wild Card. The Padres would either host the Phils, or travel to New York.
There also remains the possibility that there will be a pair of two-way ties needing to be broken, and they will be created only if the Rockies win Sunday and the Padres lose, while the Mets and Phillies both lose to end their Wild Card bids.
If the Mets and Phillies end up tied in the NL East: You already know this one; they'll play one game in Philly on Monday to crown the champ. And if you're wondering why the Phillies don't just get the division title based on their season-series victory over the Mets, it's because head-to-head tie-breakers are used only when both teams already have a playoff spot secured, and they simply determine seeding. Any regular-season tie that would send the loser home for the year has to be broken on the field.
If the Padres and Rockies finish in a tie for the Wild Card: A one-game playoff will be played Monday at Colorado.
