How do you calculate earned runs for a pitcher in baseball?

this is easy enough, these people are making it more difficult than it really is.\n\nIm not sure if your just talking about Earned Runs, or the ERA, which is the earned run average... so i will describe both.\n\na run is "earned" when the run is scored without the assistance of a fielding error.  so all runs are earned unless the runner has reached base by error, or a runner was allowed to score by error.  \n\nNow Earned Run Average (ERA) is figured out by dividing the amount of earned runs by the amount of innings pitched, then multiplying by 9 innings.  For Example...\n\nIf a starting pitcher pitches 5 innings, allowing 1 run... you take (1/5) and that equals 0.2.  Then you take 0.2 x 9 innings and get an era of 1.80 ERA.  \n\nHope that helped!

In a league using Rotisserie scoring, fantasy teams are ranked from first to last in each of several statistical categories. Each fantasy team receives points in each category based on how they rank in the league. Each team's category points are totaled to determined their overall rotisserie score. \nThe maximum number of points that a team can earn is equal to the number of scoring categories within a league multiplied by the number of teams in the league. Similarly, the lowest number of points that a team can earn is equal to the number of scoring categories multiplied by one, which is the lowest score that can be achieved in any category. \n\nIf you are in a 12-team league, the team with the most home runs will receive 12 points, the team with the second most will receive 11 points, etc. In the case of a tie, each team involved receives an average of the total points due -- i.e., in the above example, if two teams were tied for first in homers, each would receive 11.5 points [(12 + 11) / 2 = 11.5]. \n\nSo, if you were playing in a league with 12 teams and 12 scoring categories, the lowest point total possible is 12 [12 * 1 = 12] and the highest is 144 [12 * 12 = 144]. \n\nRotisserie standings reflect cumulative season stats and not any single-day accumulation of stats. Your rotisserie total may rise or fall from day-to-day depending on how your rank in each category was impacted by the addition of stats from the most recently completed day.

It really depends on if you are starting for the team or coming in as a reliever. if you are starting im gonna assume it is a five man rotation.so you pitch day one ice your arm well after pitching.day two rest.day three throw about 30 to 40 pitches not full speed just to keep the motion and location (down and away is not always the key you have to know the hitter better then that yes keeping the ball low induces ground balls but just low and away they will catch on) ice your arm after day three. day four 20 to 25 min of long toss. ise your arm. day five rest.

According to the official MLB rules book:\n\nSAVES FOR RELIEF PITCHERS \n10.20\nCredit a pitcher with a save when he meets all three of the following conditions: (1) He is the finishing pitcher in a game won by his club; and (2) He is not the winning pitcher; and (3) He qualifies under one of the following conditions: (a) He enters the game with a lead of no more than three runs and pitches for at least one inning; or (b) He enters the game, regardless of the count, with the potential tying run either on base, or at bat, or on deck (that is, the potential tying run is either already on base or is one of the first two batsmen he faces); or (c) He pitches effectively for at least three innings. No more than one save may be credited in each game.

It goes to the first pitcher, in this case, but not always.  The official rule is 10.18(h):\n\nA relief pitcher shall not be held accountable when the first batter to whom he pitches reaches first base on four called balls if such batter has a decided advantage in the ball and strike count when pitchers are changed.\n\n(1) If, when pitchers are changed, the count is\n2 balls, no strike, \n2 balls, 1 strike, \n3 balls, no strike, \n3 balls, 1 strike, \n3 balls, 2 strikes,\n\nand the batter gets a base on balls, charge that batter and the base on balls to the preceding pitcher, not to the relief pitcher.\n\n(2) Any other action by such batter, such as reaching base on a hit, an error, a fielder's choice, a force out, or being touched by a pitched ball, shall cause such a batter to be charged to the relief pitcher.

it's the # of bases per at bat.... add up the # of total bases (1 for single, 2 for double, 3 for triple, 4 for homerun) and divide by the number of at bats

There really are no standardized rules for the pitching machine. They are local adaptations of established rules.\n\nMost would have the ball become dead, batter is awarded first base, and all runners advance one base(although some advance the runners only if forced).

Slugging percentage is calculated as total bases divided by total number of at bats. Total bases are calculated like this:\nSingle = 1 base\nDouble = 2 bases\nTriple = 3 bases\nHome run = 4 bases\n\nYou add up all the hits using the point system above, and then divide by the number of at bats.\n\nFor example, if a batter takes 10 at bats, during which he hits 2 singles, a double, and a home run, he has 8 total bases (2 for the 2 singles, another 2 for the double, and 4 for the home run). You take 8 and divide by 10, for an .800 slugging percentage. That's a really good slugging percentage.

Taken straight from the MLB Rules - Rule 1.04 The Playing Field\n\nThe pitcher's plate shall be 10 inches above the level of home plate. The degree of slope from a point 6 inches in front of the pitcher's plate to a point 6 feet toward home plate shall be 1 inch to 1 foot, and such degree of slope shall be uniform.

It is the same as in baseball i think.   You take the total of bases from your hits.  1 for a single 2 for a double 3 for a triple and 4 for a homerun and divide it by the number of at bats.

There's no single answer to this. It depends on the number of runs per inning. If one inning had no runs, the product would be 0. \n\nIf one run is scored every inning, the product would be 1, but the sum would be 9 (for 1 team). But if two runs are scored every inning, the product would be larger than the sum.

In order to qualify for the award a player must have accumulated, prior to the season under consideration:\n\nFewer than 130 at bats and 50 innings pitched in the major leagues or \nFewer than 45 days on the active rosters of major league clubs (excluding time on the disabled list or any time after rosters are expanded on September 1)

It, like the whole game of baseball, is sort of complicated math, or at least a lot of it ;-). To get slugging percentage you divide the total number of bases, of all their base hits, by the total number of times they were at bat. Just FYI the abbreviation is SLG. :-)

A pitcher is credited with a perfect game when NO batter of the opposing team reaches base in ANY MANNER (no hits, no walks, no erros, no hit batsmen, no being awared first because of interference or obstruction, none of that stuff).\n\nOne poster had it right when they said, "three up, three down, every single inning".\n\nIf a pitcher pitches a 'perfect' game for nine innings, but the game goes into extra innings because of his own team's inability to score a run, and the pitcher allows a baserunner in extra innings, he is not credited with a perfect game.\n\nThis happened to a Pittsburg Pirate pitcher named Harvey Haddix in 1959, against the then-Milwaukee Braves. He pitched twelve perfect innings before surrendering a couple of hits in the 13th inning, and he lost the game.\n\nFor many years, Haddix was listed in the record books as having pitched a 'perfect' game, but about 15 years ago, baseball amended their rules, and removed Haddix's name from the "Perfect Game" list, although most record book sources will acknowledge that Haddix did pitch 12 perfect innings before allowing baserunners in the 13th.\n\nAlso, a pitcher can not be credited with a pefect game if he allows no baserunners in a rain-shortened game, even if he wins the game. It must be nine or more innings.\n\nJohn Lee Richmond and Monte Ward threw perfect games just 5 days apart in June of 1880, these were the only two perfect games of the 19th century.\n\nRandy Johnson threw a perfect game in 2004, this is the only perfect game of the 21st century so far.\n\nIn between, there were 14 perfect games pitched in the 20th century.\n\nAltogehter, 17 pitchers have thrown perfect games.\n\nHall of Famers who threw perfect games (6):\n\nMonte Ward 1880\nCy Young 1904\nAddie Joss 1908\nJim Bunning 1964\nSandy Koufax 1965\nCatfish Hunter 1968\n\n\nNon-Hall of Famers who threw perfect games:\n\nJohn Lee Richmond 1880\nCharlie Robertson 1922\nDon Larsen 1956 WORLD SERIES (only W.S. no hit game)\nLen Barker 1981\nMike Witt 1984\nTom Browning 1988\nDennis Martinez 1991\nKenny Rogers 1994\nDavid Wells 1998\nDavid Cone 1999\n\n\nThere is also one future Hall of Famer who threw a perfect game:\n\nRandy Johnson 2004\n\nAs you can see, a perfect game is pretty rare.

Multiply the total number of earned runs by nine, and divide the results by the total innings pitched.
