Castillo walked one and struck out one in a scoreless ninth inning Tuesday to record his 15th save of the season, and first since joining the Mariners, in a 4-2 win over the Rays.

EDGE Analysis

The right-hander got some revenge against his former club, fanning Brandon Lowe as he picked up his first career save in a uniform other than Tampa Bay's. Castillo has already set a new career high in saves on the season, but he figures to get most of the opportunities in Seattle over the final two months as opposed to splitting the load in the ninth as he did in Tampa.
