you do not say that the pitcher is pitching a perfect game
A perfect game for a pitcher is one in which the pitcher faces the minimum of 27 batters and does not let any of them get on-base.
Relief Pitcher - video game - happened in 1994.
The pitcher of record is the pitcher who will gain the win or loss when the game ends.
Relief Pitcher - video game - was created in 1994-05.
No. Once a player is removed from the game, they cannot re-enter that game.
No. In high school baseball, once a pitcher is called out of a game he is done for the day.
A shizz ton of times.
If pitchers' team is ahead when he leaves the game (all runners left on base that score, are charged to the pitcher that left them on base), he gets the win. The pitcher must pitch at least 5 innings in a game over 6 innings to get the win. If it is a tie game and the relieving pitcher's team wins, relieving pitcher gets the win. Otherwise he is charged with the loss. If the relieving pitcher's team is winning when he enters as a pitcher and then loses the game, the relieving pitcher is charged with a loss. If the relieving pitcher's team is winning when he enters the game as a pitcher and wins, the relieving pitcher is given a Save.
It's pretty simple really - a pitcher is credited with a complete game if he is the only pitcher for his team in an official game. There is some argument as to whether a pitcher would be credited with a complete game if say, the starting pitcher didn't get any outs, then a reliever came in and finished the game. He got all the outs in the game - so did he get a complete game? Semantics, semantics...
