Fortunes rose and fell for a handful of Mississippians on an eventful Sunday in the big leagues. In Atlanta, the Braves completed a stunning sweep of the New York Mets with former DeSoto Central High star Austin Riley playing a key role in a pivotal third inning. In Milwaukee, Mississippi State alum Hunter Renfroe gave the desperate Brewers life in the ninth only to see their playoff hopes virtually crushed by Miami in the 12th. In San Diego, ex-Ole Miss standout Lance Lynn, playing a spoiler role for the Chicago White Sox, beat the Padres — but only after the Brewers’ defeat had locked up a playoff berth for the Pads. … Powered by homers from Mississippi Braves alum Dansby Swanson and Matt Olson, the Braves beat Buck Showalter’s Mets 5-3 to virtually clinch the National League East. “If I know these guys, they’ll rebound and look to make somebody feel their pain,” Mets manager Showalter, the former MSU star who is also feeling that pain, told mlb.com. The Mets had taken a 3-1 lead in the third and had runners at the corners with no outs when Mark Canha hit a roller down the third-base line. Riley charged and made a split-second decision to let the ball go. It hopped foul. Had Riley fielded it, the runner at third would have scored. Had it stayed fair, at least one run would’ve scored. None did. Charlie Morton, the veteran ex-M-Braves right-hander, retired Canha and the next two hitters. In the bottom of the third, Riley reached on an HBP that loaded the bases with two outs, and he ultimately scored the go-ahead run on a Travis d’Arnaud hit. Braves relievers locked down the win, reducing the defending world champs’ magic number to claim the East to one with three games left at Miami. “You come at the kings, you better not miss,” said Madison native Ben Ingram, the Braves radio voice. … The Brewers trailed 2-1 in the ninth when Renfroe doubled with one out and scored the tying run on a Kolten Wong knock. Alas, Milwaukee fell in the 12th. Coupled with Philadelphia’s win against Washington, the Brewers’ elimination number is now one. They’ll send ex-MSU standout Brandon Woodruff (13-4) to the bump today against Arizona. The Phillies face Houston on the road. One Brewers loss or one Phillies win in the final series eliminates Milwaukee from the NL wild card chase. … At San Diego, Lynn (8-7) pitched great (seven innings, one run) in the final outing of what as been a disappointing season for the big right-hander and his Chicago team. After the game, a 2-1 Chicago victory, the White Sox had to watch the Padres and their fans at Petco Park celebrate a wild card berth. P.S. Former Delta State star Dalton Moats celebrated a Triple-A championship Sunday after the Durham Bulls, Tampa Bay’s affiliate, beat Reno 10-6 in Las Vegas. The lefty reliever, who didn’t pitch in the finale, had a 3.60 ERA in 51 games this season, his sixth in pro ball.
