"It's been something we know he can do but we push him a little bit to make sure we can get it out of him".
Said Turner: "Everyone knows what the goal is". "It sounds easy but it's not but when you are out there and the games are on the line and perhaps you have confidence in one pitch or another pitch". At 49-60, the Mets are 11 games under.500 for the first time since July 2014. "Both sides of the ball as a team are clicking". Now you've got to learn how to pitch when you're just OK.

As the Mets rotation has morphed from a strength to a weakness this season, Steven Matz's regression has been as surprising development. In five career starts against the Mets, Ryu is 3-0 with a 1.69 ERA, 0.94 WHIP and 31 strikeouts in 32 innings. In his last six starts he has thrown 34 2/3 innings and struck out 38 batters, posting an ERA of just 2.20.
In his 11th start of an injury-plagued season, Matz allowed three runs in the first inning.
