Vizcaino surrendered two runs on two hits and a walk en route to a loss against the Phillies on Wednesday.
In his last four appearances, Vizcaino has struck out a pair and walked six (3.1 innings), pushing his ERA from 1.93 to 2.75 during that span and increasing his WHIP from 1.22 to 1.44. There is no indication from the Braves that he's in danger of losing his role as the team's closer, but Vizcaino's performance in the next few appearances is worth monitoring closely.
