The four scouts allow a 12-year-old boy riding a donkey while pulling three horses behind him to cross their path and pull up to the stadium that houses the Astros’ Dominican Summer League team—which is more the norm for what clubs typically have in the D.R. currently.
It’s a cinderblock façade painted black on the outside, with hand-painted block letters spelling out “HOUSTON ASTROS” next to the club’s trademark star. Inside, it’s much like many minor league facilities in the States were built in the 1930s or 1940s.
