선발투수
Starting pitchers, and sometimes long relievers, will often face batters who hit from both sides of the plate as a matter of course. This is considered a part of their job, and the ability to retire batters from either side of the plate is an important asset for any starting pitcher. Most starters, especially those who rely on ball movement rather than power, are still stronger throwing against one side of the plate, however, the difference is often less pronounced than that for pitchers in the bullpen. Late in close games, when the starter is tiring and baserunners become more important, a starter may be lifted for a specialist, but a starting pitcher is "very" seldom replaced with a specialist without having first worked deep into a close ballgame.
