I was stuck on Enrique for quite a while for two reasons 1. CPUs are OP when it comes to hitting 2. my TV has about .1 seconds of input lag Eventually, though, I changed my strategy while at bat and started swinging freely. Once I did that, I scored a lot more and won pretty quickly.
GG - in my opinion Baseball is the hardest sport to get all 10 stamps in. (But you'll need some luck in Golf, I know why you do it last.) "The game pays out skillpoints based on how dominant you are, not what level your opponent is. I wish I knew this back when I was grinding for the other two champion matches." If you play Tennis against another player in a Local Game you do not get Skill Points (at least I am not getting them).
I know I’m 2 years late, but when you’re at level 15 when you lose to level 20 CPUs and it then gives you level 15s about 6 rounds later it gives you level 20 again (unless it’s different in tennis than baseball) I’m still at level 15 and I won 4 times out of 6 on level 15 CPUs and then I got level 20 again
