Ahh, but that's not how these guys operate. Some minor tweaks were applied to further distance the game from a slew of other baseball titles. Errors are more varied, and include very believable throwing mistakes. Diving infielders can throw from their knees as in the past, but this year, they don't always attempt a throw. The variety of hits has also been expanded.
Ground balls have a little more bounce than years past.
These may not sound like major changes, but when you're so close to perfection, there's not much else you can do. Probably the best thing they did to the gameplay was not changing it to the point where they actually altered the way the game plays. A full 9 innings can be completed in just over 30 minutes, and all the while, the plays will play out true to the game. There may be the occasional slugfest, where six homers can be hit, but at least you can understand the reason WHY they were hit - if you serve up too many strikes, you will pay for it. On the other side of the plate, you can tee off on sub-par pitchers, especially once they're a bit fatigued.
