The MLB trade deadline is fast approaching (seriously) and it'll heat up big time once the All-Star break comes and goes. If you are leading your division, it's time to start thinking about what you need to add for the stretch run and into the postseason. That includes what prospects you're willing to move to better your big league squad. Top prospects will likely switch teams in one of these blockbuster deals, but here's every division leader's most untouchable prospect ahead of the deadline.


6. AL West: Houston Astros- OF Kyle Tucker

Chicago White Sox v Houston Astros

We've been hearing about outfielder Kyle Tucker ever since he was a top-five pick back in 2015, and he made his big league debut last year for the Houston Astros. I don't know what else he has to do to be an everyday player for the Astros, but no matter what they want to acquire at the deadline, Tucker is an instant deal-breaker. Tucker has all the tools to be a future star, and in 70 games at Triple-A, he has 23 home runs and a .985 OPS. Yeah, I'm not moving him.


5. AL Central: Minnesota Twins- RHP Brusdar Graterol

Minnesota Twins v Milwaukee Brewers

Former No. 1 overall pick and top prospect Royce Lewis is nearly untouchable for the Twins, but with Jorge Polanco firmly entrenched as an MVP candidate at short on a cheap extension, you wonder if they could be enticed to move the toolsy Lewis for rotation help. With that in mind, the guy they can't part with is right-handed pitcher Brusdar Graterol, who is 5-0 with a 1.89 ERA over nine starts at Double-A. Minnesota needs to continue developing pitching and relying on internal options, and he's close enough to the big leagues that he could make his debut next year.


4. AL East: New York Yankees- OF Estevan Florial

New York Yankees v Boston Red Sox

Estevan Florial isn't having a great year in a small sample size (15 games) at High-A Tampa, but he's a five-tool talent, and the Yankees need to find out what he becomes. Florial has missed time due to injury, so his value isn't as high as it could be. That means they should hang on to the 21-year-old and be patient.


3. NL West: Los Angeles Dodgers- INF Gavin Lux

Chicago Cubs v Los Angeles Dodgers

Keibert Ruiz is one of the top catching prospects in the minors, but the Dodgers should make sure to hang on to infielder Gavin Lux ahead of him. He's proven to be an all-around player, even if he doesn't stay at shortstop long term. Lux has defensive versatility, and he's showing the power we were promised this year, belting 13 homers with an .896 OPS over 64 games at Double-A.


2. NL Central: Chicago Cubs- SS Nico Hoerner

Chicago Cubs v Washington Nationals

The Chicago Cubs have been more than willing to trade their top prospects for proven talent so they can win now, but shortstop Nico Hoerner needs to stick around. They can't keep trading their top position player prospects. I'm not telling you Hoerner will be Gleyber Torres or Eloy Jimenez, but he is a top-100 prospect, and I'm sure they wish they had one or both of those guys around.


1. NL East: Atlanta Braves- OF Cristian Pache

Arizona Fall League All Star Game

The Atlanta Braves have a ton of young talent in their system, so there are several players they should view as untouchable. However, outfielder Cristian Pache has elevated himself at their top prospect, and he could be very close to being their center fielder of the future. Pache has been lauded for his defense for years now, but the bat is starting play big time, and he's hitting .297 with 32 extra-base hits (nine home runs) and 41 RBI. The 20-year-old has All-Star written all over him. Come on, Atlanta. Trade from that young pitching stockpile instead.
