Does handedness count for reserve players?

When a reserve uses a live starting performance the handedness of the opposing SP does not matter. But, when a non-live starting performance is used it does matter. Here's how it works. When a reserve enters the game, the first priority is whether to use a true starting appearance or a non-starting appearance (like pinch hitting).  When the game needs the starting type it will first try to use a live performance - no matter who the batter happened to face that day.  If there isn't a live performance to use, the stat will come from the stat pool in which the player currently has more starts (vs. LHP or vs. RHP).

For example, if Jones enters the game as a reserve and his stat pool has 8 starts against RHP and 2 start against LHP and the game needs a starting-type performance (as opposed to the pinch hitting-type) the computer will randomly select one of the 8 starting stats.
