Depends on the batter. There's a stat for batting average with runners in scoring positions (at least one runner on at least second base). It has a lot of factors though like the batter's own psychology, the pitcher having to pitch from the stretch (an abbreviated motion to defend against base stealing when there are >0 runners on base), etc. Baseball stats by the actual teams to get an edge is the most advanced in all of sports. The internal stats of the teams likely have much more sohpicticated numbers that control for a lot more variables.
