I did this in Road To The Show mode as a created catcher. I don't think it matters what type of player you choose to be (I chose a power player) but if you pick one based on fielding that might improve your chances. Just focus on having a strong throwing arm.
Once you play the exhibition games and get drafted, then you can try for this achievement.
You're pretty much always put into situations where there is a runner on first or 2nd trying to steal a base. Just anticipate the base and start pressing the base before the pitch gets to you then quickly line up the throw and hit
to throw it. With enough tries, you'll eventually get this. I found that the runner pretty much always goes when the pitcher picks their own pitch. When you call the pitches, they go less often. I kept trying to call a pitchout with
+
and they never ran. I got this in my 3rd game, took less than 30 minutes from creation to playing time.
*I don't believe this works in the exhibition games when you're being scouted. I threw out a base runner trying to steal and the announcer said 'perfect throw' and it didn't pop.*
