I would say in my experience I tend to be over-aggressive with guys I expect to perform well...look for a fastball and take a big rip at it no matter what. Especially when I get in a slump with these guys I constantly have to remind myself to be patient. The AI in the game is very good and recognizes patterns and will take advantage of them especially at the higher levels. Press select and see how theyre pitching him, they will develop tendencies as well. They will pitch around you so expect to get walked a bit. A lot of at-bats the only strikes you'll see may be borderline. Don't take a power swing unless it's meat in his wheelhouse, just use contact swing to ensure you get the good part of the bat on the ball and let it fly. I know you didn't ask for a hitting tutorial so I apologize in advance if I just wasted your time. Just passing along some of my experiences with big hitters and maybe you're trying to be too aggressive as well, and this is what I try to keep in mind when I'm at the plate with Vlad, Hamilton, Cruz, and co. I feel you because I'm in a nasty slump with both Cruz and Michael Young and I still catch myself trying to take a rip at the first pitch hoping its a strike. Next thing I know 0-1 and pitcher's got my number. Just gotta be patient, make them come to you on a hitters count, and eventually you'll work out of it. Good luck!
