Dominguez has allowed just one run in 5.1 innings so far this spring, striking out five while walking one.
Dominguez's role for the upcoming season remains unclear. The 24-year-old led the Phillies in saves last season with 16, but the team brought in David Robertson over the offseason. The Phillies reportedly want to use Robertson in a versatile, high-leverage role, in line with manager Gabe Kapler's progressive approach. Dominguez also fits that role well, as his recent experience as a starter enables him to work longer outings. It's possible that the saves will go to whomever happens to still be available in the ninth inning. A clearer picture of the late-inning breakdown may not emerge until the season gets underway.
