Here's a look at some facts and figures from a crazy day in St. Louis.
• The Mets used 21 players, including seven pitchers, with three relievers throwing multiple innings. Pitcher Jacob deGrom was used as a pinch-hitter in the 17th inning. Meanwhile, the Cardinals deployed 19 players, including eight pitchers, with relievers Carlos Villanueva and Carlos Martinez (normally a starter) throwing four innings apiece. St. Louis hadn't used multiple relievers for that many innings since June 1, 1968, also against the Mets.
• At 18 innings, it was the second-longest game in the Majors this season, behind a 19-inning contest between the Yankees and Red Sox on April 10.
