The Pirates have not only won six consecutive games heading into their interleague series that begins Friday afternoon in Seattle, but they are coming off a three-game sweep of the St. Louis Cardinals in which they didn’t allow a run. A team that was just 12-26 when Derek Shelton was fired as manager on May 8 has been playing better than .500 ball for replacement Don Kelly. “I feel like this is the team we were rolling out with in spring training,” Pirates shortstop Isiah Kiner-Falefa said. The Pirates have outscored their opponents 43-4 during their winning streak, and their staff has combined for 31 consecutive scoreless innings.
