Soon to turn 28, Santos has thrown 36 2/3 major league innings over the past two seasons. He has allowed 21 earned runs in that span, with eight home runs putting a big dent in the bottom line. Santos does carry a solid combination of forty strikeouts against 14 walks in his still-nascent MLB career.
Formerly a starter, Santos worked almost exclusively in a relief capacity in 2018 in both the majors and minors. In 42 2/3 frames spread over twenty appearances for Triple-A Buffalo, Santos pitched to a 2.74 ERA with 8.4 K/9 against 2.7 BB/9.
The multi-inning capabilities are surely of interest to the Rays. Beyond that, Santos has also shown some interesting skills. He carries a 14.2% swinging-strike rate during his time in the majors and last year averaged over 94 mph with his fastball.
