The frustration the Boston Red Sox experienced on Wednesday night can be captured in one at-bat in the bottom of the fifth inning. Former Mississippi State star Hunter Renfroe was up with the Red Sox down 1-0, two runners on, no outs. The Crystal Springs native, who had 31 homers and 96 RBIs this season, got ahead in the count 2-0. Was it his time? No. Houston starter Framber Valdez threw his signature sinker, and Renfroe rolled into a 6-4-3 double play. The next batter, Alex Verdugo, also bounced out. Boston got nothing, and the Astros then blew up for five runs in the sixth en route to a 9-1 victory that puts them ahead 3-2 in the American League Championship Series that heads back to Houston. Valdez was brilliant over eight innings, limiting the Red Sox to three hits. The Sox had just five hits in a 9-2 loss in Game 4 on Tuesday. Several of Boston’s big bats have gone cold. Kyle Schwarber is batting .143 in the series, Xander Bogaerts .227, Verdugo .235. Renfroe’s slump has been particularly pronounced. He is 1-for-14 (.071) with one RBI, that coming in Game 1. He was 0-for-3 with a strikeout and two GIDPs in Game 5. Surely, he is frustrated, as are his teammates, but he is not down, said DH J.D. Martinez. “I think Hunter’s been even-keeled all year,” he said in a nesn.com story. “I don’t see him down at all. You know, he is still going up there. He puts up tough at-bats.” Backs to the wall, the Red Sox need some of those tough at-bats to produce hits and runs. P.S. Unsung hero in Atlanta’s crucial Game 4 win in the National League Championship Series: A.J. Minter. The former Mississippi Braves left-hander (2016-17) pitched two near-perfect innings in middle relief in the Braves’ 9-2 win against Los Angeles. Minter pitched the sixth and seventh innings when the lead was a precarious 5-2 and threw 16 of 22 pitches for strikes. He yielded just one hit. With ace Max Fried, another ex-M-Braves standout, starting tonight in Game 5, the Braves, up 3-1, have to feel they’re in pretty good shape.
