The North American Society of Cherry-Picked Short-term Stats says that since 6/20, or about a month, at AAA, Ribalta has made 10 appearances,12.2 IP, with 1.42 ERA, 18 Ks, and 5 BBs. 40 K%, 11.1 BB%. BAA .100, with a WHIP of 0.71. Will guess he's ready for a call up when a roster slot opens (trade of Floro most likely).
FWIW, of the 4 of the 5 BBs came against Buffalo and Worcester, AL East AAA teams. That was also 8 of his Ks. I wonder if the AL teams teach more grinding ABs, deep counts, etc...
