This article was originally published on www.si.com/mlb/orioles as Baltimore Orioles' top prospect ranked top five in MLB. Within the last week, the Baltimore Orioles have seen two top prospects make their big league debuts.

The New York Mets acquired an All-Star reliever at the trade deadline, but he may not be around for long. He could leave for the Baltimore Orioles.

Baltimore now has big shoes to fill at the back of its bullpen as it looks to get back into contention next season.

The Orioles announced on Wednesday that their All-Star relief pitcher Félix Bautista underwent surgery on Tuesday to repair a torn rotator cuff and torn labrum. Bautista will now miss at least the next 12 months as he recovers from the surgery.

The Orioles have improved their play recently, winning five out of their last six games, and they have a couple of younger players to thank for providing a spark to the club.

Samuel Basallo’s wait is over. The Orioles promoted the catcher, the club’s top prospect, to the big leagues on Sunday.

The Pittsburgh Pirates are reportedly promoting baseball's top pitching prospect to make his MLB debut as early as Friday.
