Before this afternoon’s game against the Cubs, the Braves called up relief pitcher Rolddy Muñoz. Atlanta also activated utility player Luke Williams from the 10-day injured list. Those accounted for Atlanta’s two expanded roster spots. Muñoz was added to the 40-man roster last offseason to keep him out of the Rule 5 draft. This is his first big league call.
The 25-year-old righty now has a good shot to make his MLB debut in the next few days. Muñoz, the twin brother of former Brave farmhand and current Cardinals reliever Roddery Muñoz, was an amateur signee out of the Dominican Republic. Baseball America ranks him the #18 prospect in an admittedly thin Atlanta farm system. He’s a two-pitch reliever with an upper 90s sinker and a slider that BA rates as a 70-grade (plus-plus) offering. It’s the kind of raw stuff that could play at the back of a bullpen, but Muñoz’s below-average control probably pushes him more towards middle relief.
Muñoz has divided the season between Double-A Columbus and Triple-A Gwinnett. He has combined for 55 2/3 innings with a 2.75 earned run average. Muñoz has walked an alarming 13% of batters faced with a slightly below-average 21.4% strikeout rate. The shape on his fastball causes it to play more as a ground-ball pitch than a huge swing-and-miss offering despite its velocity. Muñoz has gotten grounders at a near-52% clip this season. The Braves will see how his stuff plays against big league opposition as the season winds down, probably with an eye towards letting him battle for an Opening Day bullpen spot next spring.
