2019 Fantasy Outlook
Dominguez entered the year as a starter with zero appearances above High-A. He finished it with 16 saves and a 2.95 ERA in 58 major-league innings. It took the 23-year-old just 11 relief appearances in the high minors to convince the Phillies to call him up and just five more in the big leagues for manager Gabe Kapler to give him his first save chance. After beginning his MLB career with 12 scoreless outings (in which he allowed just three baserunners), he came back to Earth a bit, but his final line remained strong. Dominguez's fantasy value in 2019 will be determined in large part by Kapler's bullpen usage, which was unconventional in his first year at the helm. Nine different players recorded a save, and five different relievers were trusted for multiple saves in a row. Dominguez isn't quite in the Josh Hader tier of fantasy-relevant non-closers, but his 32% strikeout rate gives him some value in deeper leagues even if his save opportunities don't increase.

Stat Review
How does Seranthony Dominguez compare to other relievers?
This section compares his stats with all relief pitcher seasons from the previous three seasons (minimum 30 innings)*. The bar represents the player's percentile rank. For example, if the bar is halfway across, then the player falls into the 50th percentile for that stat and it would be considered average.

* Exit Velocity, Barrels/BBE %, Balls Hit 95+ MPH %, and Spin Rate are benchmarked against this season's data (min 20 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.
  • K/BB
    Strikeout to walk ratio.
  • K/9
    Average strikeouts per nine innings.

2018 Fantasy Outlook
Dominguez always had great stuff, but command, control and durability had been issues for him as a starter, so the Phillies transitioned him to a relief role in 2018. As expected, he took to his new role quite well, rocketing from Double-A to the majors in a month's time. His fastball is parked at 99 mph and his slider makes hitters look foolish when he is on, so high-leverage work is a cinch. Hector Neris can miss bats, but his control comes and goes, so if Dominguez performs as expected, he could be a source of saves sooner than later.
