BOSTON — Back in Boston after spending the weekend home welcoming his new child, Brayan Bello returned to find his team in disarray.In the few days he was gone, Cooper Criswell caught COVID, James Paxton hurt his leg and the whole bullpen had been burnt out trying to cover for them. On top of that, Jarren Duran earned himself a twogame suspension for making a homophobic remark, bringing a storm of controversy into the clubhouse at a time the Red Sox were already at their lowest.The Red Sox needed a big outing from Bello in the worst way, and after season filled with false starts, the new father came through when it mattered most.Bello delivered one of his best performances of the season on Monday, allowing one run over six strong innings, and the Red Sox went on to win, 5-4, in a 10-inning thriller on a walk-off single by Rob Refsnyder.Trailing 4-3 entering the bottom of the 10th, Enmanuel Valdez hit a towering RBI double to the deepest part of the ballpark to tie the game, and then Nick Sogard singled to put runners at the corners with no outs. The Red Sox later pinch hit Mickey Gasper with the game on the line in his MLB debut, and the rookie was able to draw a walk to load the bases with one out.Two batters later, Refsnyder came through with the gamewinner.The win also snapped Boston’s four-game losing streak and moved the Red Sox to within two games of the Kansas City Royals in the wild-card standings.Boston broke the ice in the bottom of the fourth when it loaded the bases and scored on a sacrifice fly by Sogard. Ceddanne Rafaela nearly drove in at least one more, but his scorching liner was snagged by the second baseman, prompting the rookie to fling his bat in disgust.Texas tied the game on an RBI single by Marcus Semien in the top of the fifth, but in the bottom of the frame the Rangers pitchers completely lost the plot, walking five men and allowing two runs to score.Things started off innocently enough. Starting pitcher Tyler Mahle walked the leadoff man but struck out the next two. With his pitch count up to 92 and a pocket of lefties coming, Rangers manager Bruce Bochy opened for lefty and recent trade deadline acquisition Andrew Chafin.The move quickly backfired.Chafin first intentionally walked Rafael Devers,
