Title: Major league pitchers beating all 30 teams
Content:  Major League Baseball (MLB). It is very rare for a pitcher to record a win against every team. In earlier times, two factors made it nearly impossible to defeat all teams in both leagues (even before expansion increased the number to 30):  In any case, defeating all teams is more likely only if a pitcher has a long career. Assuming that good health and rotation timing allows a top notch pitcher to beat every one of his team's opponents in a season, it will still only be 19–20 teams (14 intraleague and 5 or 6 interleague), unless he is traded. It is far more likely that his wins will come against 10 to 12 teams, most of which he has already beaten.

Content: Before the era of free-agency, in which players are free to move to another team at the end of their contract, a pitcher would play for only a few teams, and could not, of course, win a game against his own team. ; Before inter-league play began in June 1997, a pitcher would see only half of the 30 teams in any single season, unless traded to a team in the other league.
