This happened twice to me in the last couple of days. Opponent will pause the game and will run the clock to 1 second, then he'll request a friendly quit if they're losing. The goal is to get you to click accept making you think the clock expired and you want to accept before they "come back from pausing the game". But if you accept the friendly then the game won't count for either player.
The 2nd player chose not just to try this but to then have a freeze off after the last out. Forcing me to quit since I have better things to do with my life then wait (plus is just an event game of 3 innings). I then tried to block him and report him but it seems he blocked me first so that I did not get a chance to report him. I wish I could post his PSN but I've read if you do that then you get in trouble. However, feel free to look at my game log, the final score was 6-2 and I took the L. Block him so that you don't have to deal with this BS. I can't think of any way to report him now.
