Down 10-15 against Marquez. Beat it with 8 outs left. I'm a scrub player who uses directional. I'll never be WS or go 12-0, but if I can beat Showdown, you can beat showdown.
Played all the way through; failed three blue missions because I got antsy, beat both mini-bosses.
I know it's been said before, but the best advice is to be patient, only swing on two strikes (or if you're sure it's a meatball). Draft for power. Be willing to take a K instead of a DP. Pause it and take a few minutes if you feel yourself getting in your own head. (Special shoutout to Stryder's helpful tips post, btw.)
Anyway, it's not impossible by any stretch, and it's a great way to grind.
Welcome to the team, Roy Oswalt. Special shouts to Charlie Blackmon for a timely grand slam, and to Nelson Cruz, who hates baseballs.
Good luck.
