The San Francisco Giants brass made the decision to move Raffi Vizcaino to the bullpen during the offseason.
The 23-year-old had turned in back-to-back mediocre seasons as a starter, posting a 4.98 ERA and 1.33 WHIP in 77.2 innings at Single-A in 2017, and a 4.65 ERA and 1.54 WHIP in 79.1 innings at High-A in 2018.
A spike in his walk rate from 3.2 to 5.9 BB/9 last season likely played a major role in the front office’s decision to pull the trigger on moving him into a relief role.
What a decision that has been.
