Destructoid has just posted their second MLB 2K11 preview. This one detailing Franchise Mode, My Player and more.
"I brought up 2K10’s messed-up manager AI for pitchers, and Bailey freely acknowledged that it was awful; he told me I was being too nice about a system where a manager left my starter in for twelve innings. But 2K11 doesn’t go by pitcher stamina or energy, concepts that are “too videogamey,” according to Bailey. “If it says ‘52 energy,’ what does that mean to me? Can I pitch three more innings? One more inning?” Instead, in-game managers will focus on your pitch count, just like real MLB coaches. On the pause screen, you’ll see your current and expected pitch count, and when you reach the upper limits of the expected range for the day, you’ll probably get pulled."
