Baseball pitchers are only referred to as a Southpaw if they're left handed, it's more common for left handed pitchers to be referred to as a Southpaw but it's just a general term for anyone who is left handed.
As a general rule, there are less left handed pitchers. So lefties face lefties less often and have less at-bats to adjust to them. There are probably other reasons also.
The answer is because left handed batters hit worse off left handed pitchers. There are two reasons for this. The first reason is spin. A left handed pitcher will more easily be able to put spin on a ball that causes the pitch to move from the right side to the left side of the plate (from the catcher's view). This spin moves away from a left handed hitter and toward a right handed hitter. It is believed, with lots of data to support it, that a ball spinning away from a hitter is harder to hit than one spinning closer to the hitter. That's one reason a left handed batter is worse at hitting a left handed pitcher. The other reason is sight and release points. The same principle of spin applies that a pitch moving away from the batter is harder to hit than one moving closer to a batter. Because of the pitcher's release point, a left handed pitcher will release the ball somewhere to the right of the mound (from the catcher's view) when the ball is thrown. If we assume the ball has no spin and is pitched to the center of home plate, it will have moved from the right of the mound to the center of the plate. This movement from a left handed pitcher is going away from a left handed hitter and going closer to a right handed hitter. There is not much difference between how well right handed batters fare against right handed pitchers and left handed pitchers because right handed pitchers are so common that right handed batters don't have the same level of disadvantage as left handed batters do against left handed pitchers. But the reason why right handed batters are better than left handed batters against left handed pitchers is mostly explained with spin and release points.
Only four pitchers have won four or more Cy Young awards in their respective careers, of which two, Steve Carlton and Randy Johnson, are left-handed.
It depends if the pitcher is left or right handed, a lefty will face first, while a righty will face third.
As of the 2014 season, the Colorado Rockies have 9 left handed pitchers.
