With MLB action returning following the All-Star break, teams will be focused on the trade deadline on July 31. One team to keep an eye on is the New York Yankees, who are in prime position to clinch a playoff spot. However, with pressing needs at pitching, the trade market will present the opportunity to enrich the rotation and make a run at the World Series.

The thing is, non-playoff teams will have a high asking price for their top pitchers, and will certainly want some of the Yankees' top prospects.

In that regard, here are three prospects the New York Yankees should deem untouchable in trade talks.

1. Estevan Florial - OF

Estevan Florial is New York's undisputed top overall prospect, which equally makes him untouchable. Florial is described as a five-tool player, but injuries have limited his path to the show. Regardless, Florial's potential is just too high to pass up on. The outfielder isn't expected in the big leagues until 2021, but he's indispensable.

2. Deivi Garcia - RHP

Of course, the fast-rising Deivi Garcia has caught the attention of Brian Cashman and Aaron Boone, and for good reason.
