SAN DIEGO — When Cincinnati Reds rookie outfielder Blake Dunn sat in front of his locker in the visitor’s clubhouse at San Diego’s Petco Park, his uniform pants told the story of the previous four-plus hours.When Dunn watched a fastball down the middle from San Diego Padres starter Lucas Giolito on the first pitch of an eventual 5-3 Reds victory in 11 innings on Tuesday night, those pants were solid gray, matching the color of his No. 59 jersey.Four hours and three minutes later, at 10:44 p.m. PT, Dunn’s pants were more brown than gray, covered in the Petco Park dirt after six plate appearances that included a walk, a hit, a stolen base and the eventual game-winning run, not to mention a game-saving diving play in right field to end the eighth inning with a runner stranded at third. For the first time in a week — a stretch of five games — Dunn and his teammates could exhale and enjoy a win.“The last five games we’ve been battling it out up and down, leading sometimes and fighting from behind other times,” Dunn said. “But being able to scratch and claw our way to a win (Tuesday) was huge. It feels like those are the type of wins that help get teams some momentum.”Momentum can swing both ways, and it has seemed to go against the Reds over the last month. The Reds entered May nine games above .500 and in first place in the National League Central. Yet after going 20-11 over the first month-plus of the season, the team fell to 10-17 in the second full month, dropping all but one of their seven games in June entering Tuesday.Yet, after their longest game of the season, the Reds were playing music in the clubhouse to celebrate a victory for just the second time this month.Whatever happens next, Tuesday’s win felt bigger than just one win. It’ll of course count the same statistically. But emotionally, some wins — and some losses — loom larger than others.Nearly every one of the 26 players on the Reds’ roster had a story to tell from Tuesday’s game, one in which left-hander Nick Lodolo, who is scheduled to start Friday’s series-opener against the Arizona Diamondbacks at Great American Ball Park, offered his services to manager Terry Francona if needed.Nathaniel Lowe (31), Brock Burke and the Reds finally had a reason to celebrate Tuesday night in San Diego.
