Let's take a look at a few targets at shortstop.

Expert Consensus Rank: 7
Injuries have kept Correa from reaching his full potential over the past two seasons, but he has Top 20 overall upside. He already has two seasons with 20 or more home runs and 10 or more steals. I believe he gets back to those numbers in 2019. Last season saw a career low .239 batting average. A career low .282 BABIP explains this. His current ECR of 35 overall at FantasyPros feels like a steal.

My advice at shortstop is to grab one of the Top 12 for sure. I know people have mixed feelings on Adalberto Mondesi (my No. 12) but it's crazy to think the position has 12 guys with legit Top 20 overall upside. Jean Segura is kind of getting overlooked at the end of the Top 12 tier. Segura has been super-consistent over the past three seasons and, despite playing the last two at Safeco, has averaged 91 runs, 14 home runs, and 25 steals a season since 2016. This includes hitting .308 with a .803 OPS. Segura joins a Phillies lineup in 2019 which could include one, if not both, of Bryce Harper and Manny Machado.

I saw someone make a point on twitter and I don't disagree. The point was basically Eduardo Escobar is Gleyber Torres with less speed. The speed part isn't even much different. Torres had six steals last season compared to Escobar's two. Both had similar slash lines and counting stats. Sure, Torres is 22 with a ton of upside, but the point here is Escobar is being undervalued outside the Top 20 at shortstop.

Dude is going outside the Top 40 at the position. Diaz has a 162-game average of 21 home runs, 71 RBIs, 79 runs, and six steals with a .275 batting average. Plus, he's going to the Astros, who seem to make everything they touch turn to gold.
My Rank: 39
Expert Consensus Rank: 46
Crawford has been a top tier prospect since he was drafted in 2013. This includes two times being ranked inside the top five by MLB.com. This helps keep faith in his potential as he is still just 24 years old. He's had a rough stint in the Majors to date but it's less than half a season's worth of games played. Crawford is a great contact hitter with impressive plate discipline. He can grow into an Andrelton Simmons type with more walks. His current draft price makes him a low risk option in deeper leagues and AL-only formats.
