Please note that the odds are subject to change.

New York Mets at Washington Nationals 6:45 PM EDT

The New York Mets kick off a four-game road series against the Washington Nationals at Nationals Park. The Mets come into this one sitting at a 20-26 record and have found it tough to pick up wins away from home, posting a 9-13 road record. The Nationals hold a slightly better 23-24 record overall, though they have actually been a better team on the road than at home this season. This division battle could easily display tight defense and low scoring if the starting pitchers hit their spots early.

Toronto Blue Jays at New York Yankees 7:05 PM EDT
