Early Friday afternoon was a celebration at Fenway, the home opener celebrating a team that made a surprise run to the ALCS last season, and on Jackie Robinson Day to boot. The Red Sox brought back Mo Vaughn with his son throwing out the first pitch before they took on the Twins, and the vibes were good. That quickly changed. Nick Pivetta had nothing in this game, getting through only two innings with Alex Cora looking to keep the game within reach for his offense. To the bullpen’s credit, they did a fine job at that, allowing just two runs over the final seven innings.
