This achievement requires a bit of a keen eye, and also some luck. It's a simple achievement, and I got this during my first game. There's really not much to be said about it. Once you get two strikes, get a base hit. It'll happen eventually.
If the pitcher has poor composure and keeps throwing balls, swing the bat immediately after the ball leaves the pitcher's hand.
You can always increase the player's hitting abilities, if you're having difficulties. You'll still get the achievement.
