BOSTON (AP) — Rick Porcello became the majors' first 18-game winner and the first Red Sox pitcher in 70 years to open a season 13-0 in Fenway Park, going seven solid innings in Boston's 9-4 victory over the Tampa Bay Rays on Monday night. Porcello (18-3) allowed three runs and six hits, striking out seven without issuing a walk to become the first Boston pitcher since Dave "Boo" Ferriss finished 13-0 at home in 1946 to start a season by winning his initial 13 decisions in Fenway. Matt Andriese (6-6) took the loss, giving up a season-high seven runs in four-plus innings. After the Rays cut it to 5-3, Betts lined a run-scoring double into the left-field corner. The next steps are for him to have bullpen on Wednesday before facing live hitters Saturday.
