The Cincinnati Reds have called up infielder Alejo Lopez. There were rumors around the internet on Sunday evening that it was happening, but Lopez seems to have confirmed it on his Instagram in his stories later in the night, saying this (via google translate):
This achievement is dedicated to you, mom and dad. We got to the top, to the big leagues. There were years of work, but this is only the start. I love you.
It would seem that twitter user @Rev_Strikeout was the first to report the call up. The move is not yet official.
