BOSTON — Red Sox starter Brayan Bello showed his athleticism while covering first base during the first inning Tuesday. He stretched out fully and kept his foot on the bag to complete a 3-6-1 double play and escape a bases-loaded jam. He fell to the dirt once the play was completed.

Bello had to work out of trouble but held a red-hot Mariners offense to one run on four hits in five innings in his season debut.

Boston still has a dominant Garrett Crochet, an improving Walker Buehler, and Sean Newcomb to hold down the rotation. The 14-11 Red Sox should be satisfied with their start to the season, despite fielding and strikeout woes, and will only improve with this influx of healthy arms.
