The Arizona Diamondbacks celebrate the Fourth of July by hosting the Kansas City Royals Friday in the opener of a 3-game set at Chase Field.

The Mariners bullpen has been one of the most dependable collective units on the team over the last month. The series against the Royals marked Games 11-14 of a 17-game stretch for Seattle without a day off, and the relievers have been steady throughout, often times resembling Atlas holding up the sky.
