Beaning, Dispute and Ejections in a Mets Defeat Mike Stobe/Getty Images Jason Heyward walked off the field on his own power after being hit in the face with a pitch in the sixth inning before being taken to a hospital. There are not many things that can move an entire baseball stadium to near silence. But such a thing occurred at Citi Field on Wednesday afternoon when Jason Heyward of the Atlanta Braves crumpled to the ground after taking a 90-miles-per-hour fastball to the jaw from the Mets" Jon Niese. There was a thud, audible all around the stands, and then a prolonged hush from the crowd, which was numbered officially at 22,935. Replays on the scoreboard elicited groans. The Mets went on to lose the game, 4-1 in 10 innings, apparently victimized on a missed called at first base that led to three Braves runs and two Mets ejections. But before the call, and the anger, there was concern about Heyward, who walked off the field on his own power. The Braves said he had two jaw fractures, and he will have surgery on Thursday. The team will announce how long Heyward will be sidelined after the operation. "It's every pitcher and hitter's worst nightmare," Niese said. I felt horrible. Sometimes this game can be pretty dangerous. One minute you're playing, the next minute you're down. Heyward went down during the sixth inning, after Niese had secured two quick outs. On a 1-2 count, Niese tried to elevate a fastball inside, but the ball tailed too far and struck Heyward near the earflap on his helmet. Heyward dropped to his knees first before sprawling onto his back, and he lay there squirming as the Braves" staff checked on him. Mets infielders huddled near the mound, watching as Heyward was treated. Catcher John Buck said he saw Heyward spitting up blood. Some players joined the crowd to applaud once Heyward got back to his feet. Baseball only occasionally becomes a contact sport, but balls that are thrown or batted toward a player's head represent a notable danger. After the game, the Mets right-hander Zack Wheeler was headed to the hospital to check on Heyward. The two players became friendly while working out at the same Atlanta training center. Some Mets sent out encouraging messages about Heyward on Twitter as they waited for an update on his condition. Niese looked anxious once the ball hit Heyward, taking off his cap and shaking his head. Once the game resumed, Niese allowed two straight hits, giving up his first run, which tied the score at 1-1 and canceled out Josh Satin's fourth-inning solo homer. Niese said the beaning did not unnerve him, but the results suggested otherwise. "You have to forget about it and focus on making pitches, but at the time I felt terrible," Niese said. The game's tone totally changed as it moved into extra innings. Chris Johnson's three-run homer to left in the 10th provided the go-ahead runs, but the Mets did not believe Johnson should have made it to the batter's box, and they made it known how they felt. The Mets right-hander Scott Atchison recorded two outs to open the 10th before giving up a single. The left-hander Scott Rice then entered the game to face Freddie Freeman and induced a ground ball back to the mound. Rice fired the ball to first base, and replays appeared to show the ball beating Freeman to the bag. But Jerry Layne, the first-base umpire, called Freeman safe, extending the inning. Later, when Johnson rounded the bases on his home run, second baseman Daniel Murphy expressed his displeasure to Layne and was ejected. Seeing this, Manager Terry Collins ran onto the field for a second time, this time to back up his player. He threw his cap onto the dirt, and he was thrown out, too.
