Estrada has been optioned back to Triple-A Scranton/Wilkes-Barre.
It was a short stint at the big-league level for the 23-year-old, who was initially called up earlier this week after Troy Tulowitzki (calf) hit the injured list, but he won't end up logging a big-league at-bat before getting sent back down. Infielder Giovanny Urshela was called up in a corresponding move.
