Johan Santana (5-5 3.55) vs Livan Hernandez (6-4 3.10)
TV: SNY Radio: WFAN
What to watch: Who would’ve ever thought Livan would be having a better season than Santana? That’s the case. But the Nationals have lost six of seven games now. Santana has lost two straight games in pitched poorly in four straight. The Mets need him to turn it around quickly.
