Giles pitched the ninth inning with one walk and three strikeouts to earn his first save of the season in a 3-0 win over the Mariners on Monday.
Giles is attractive as a top-10 fantasy closer because of his high-90s heater and impressive strikeout rate (14.0 K/9 in 2016). Luke Gregerson and Will Harris could be a threat to his role if he struggles, but Giles is in prime position to rack up plenty of saves for a contending club.
