Update 6:

Improvements:
Further tweaks to Pennant Race Ego assignments (slightly higher Egos to reduce offense / run totals).
Have the AI be somewhat more willing to bring in the closer in the early and middle parts of the game if necessary.
After making an out in the outfield with no runners on base, AI fielders now ensure that they throw the ball in to someone in or closer to the infield.
Allow the pitcher to be the selected fielder on more types of infield hits up the middle of the diamond.

Issues addressed:
Fixed: In online play, the ball stutters substantially after being bunted or hit on certain infield plays, especially when the fielding user is at high Ego.
Fixed: Slow motion special effects not properly working in online play.
Fixed: In online play, the batter's bunt state could become out of sync after the batting user enters the pause menu.
Fixed: Error noise fails to play when attempting to start a pitch from the stretch before the pitcher has finished coming set.
Fixed: AI-controlled outfielders still sometimes jog or hesitate while the user is controlling another fielder.
Fixed: In rare cases, the AI makes a poor decision to go for a tag out over a forced out on the back end of a double play.
Fixed: Outfielders sometimes run towards the infield on deep fly balls / home runs.
Fixed: Middle infielders sometimes run towards home plate immediately after contact on fly balls to the outfield.
Fixed: AI makes a double switch that inadvertently sees the new position player playing out of position.
Fixed: In online co-op, the catch sound fails to play and ball ribbon trail fails to disappear after the ball is fielded in some cases.
Fixed: In online co-op, balls hit to the AI in the infield can appear to get past infielders before being caught.
Fixed: In online play, on ball 4, the batter returns to his batting stance after tossing his bat in some cases.
Fixed: In online play, the substitution button would remain visible after an auto-ball resulted in ball 4.
