With the Seattle Mariners struggling to find offense, Jean Segura wasn't going to sit through a long at-bat looking for a perfect pitch. Segura chopped the first pitch from Sam Dyson into center field to score Guillermo Heredia with the go-ahead run in the eighth inning, and the Mariners won yet another one-run game by beating the San Francisco Giants 3-2 on Wednesday. Seattle came up with just enough offense to split the two-game interleague series, and it was one of the Mariners' All-Stars who came through.
