I bounced back. I struggled, but I got the difficulty back to veteran, and then it fell again. After my batting average fell to around 320 (from 420) I got it back up and finished AAA at 340 which I was OK with. I finally hit my first HR too.
First 8 games I have 30 AB and hitting 430, number 4 in the league. Got up to veteran difficulty. It won’t last though.
I got a major league contract and played spring training for the Yankees, starting off horribly and then getting my average to 310 and made the team. The difficulty dropped to beginner 3 before I worked it back up to rookie +. It will be interesting to see how I do in my first major league season and where the dynamic difficulty will go. Happy now to be in the real major league stadiums.
