Runs produced is a baseball statistic that can help estimate the number of runs a hitter contributes to his team. The formula adds together the player's runs and Run batted in, and then subtracts the player's home runs.〔Thorn, J. and Palmer, P., ''Total Baseball: The Official Encyclopedia of Major League Baseball, 4th Edition'', p. 2550, Penguin Books, New York, 1995, ISBN 0-670-86099-9〕 Home runs are subtracted to compensate for the batter getting credit for both one run and at least one RBI when hitting a home run. Unlike runs created, runs produced is a teammate-dependent stat in that it includes Runs and RBIs, which are affected by which batters bat near a player in the batting order. Also, subtracting home runs seems logical from an individual perspective, but on a team level it double-counts runs that are not home runs. To counteract the double-counting, some have suggested an alternate formula which is the average of a player's runs scored and runs batted in. Here, when a player scores a run, he shares the credit with the batter who drove him in, so both are credited with half a run produced. The same is true for an RBI, where credit is shared between the batter and runner. In the case of a home run, the batter is responsible for both the run scored and the RBI, so the runs produced are (1 + 1)/2 = 1, as expected. ==See also== *Baseball statistics 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「runs produced」の詳細全文を読む スポンサード リンク
