Statistics Used
To be successful in Scoresheet, an owner needs to concentrate on a player's individual stats such as slugging percentage, on-base average, ERA, hits allowed, etc. Other player stats such as RBI's, runs scored, and pitcher wins, losses and saves, are greatly determined by which team that player is on in the majors. These "team dependent" stats are far LESS important in Scoresheet than in other fantasy baseball games.
Batting
The actual number of singles, doubles, triples, home runs, walks and strikeouts the batter has per plate appearance that week in the majors, modified by the opposing pitcher and fielders' performance, determines his chances at each at-bat. Other stats used include a batter's previous totals for differences in his hitting against left-handed and right-handed pitchers (we use a player's actual platoon differences from the past two seasons, with 1500 plate appearances worth of league average platoon differences added in). This means a player who has hit better against right handed pitchers for the last 2 years will hit righties better than lefties during the upcoming Scoresheet season. (A player's platoon splits from the current season is NOT used - all we get during the season are a player's weekly totals, not how he did each week against RHPs and LHPs.)
Pitching
The number of hits, walks, earned runs and strikeouts the pitcher records per inning pitched that week in the majors affects each batter's chances against him. The pitcher's ERA in his major league games that week, and to a much lesser extent his wins, losses and saves, alter the probabilities of giving up an extra base hit, clutch hit, or getting a double play ball. Like batters, team dependent stats for pitchers, such as his number of major league wins, losses and saves, are not nearly as important in Scoresheet as the individual dependent stats such as ERA and hits, walks and strikeouts per inning pitched.
Base Running
The batter's RBIs and runner's runs scored totals are used in determining how far the base runners advance on a base hit, and affect the chance of a sacrifice fly. Our Scoresheet game program also takes into account such subtle factors as a runner sometimes advancing farther on a hit with 2 outs, since he can run with the crack of the bat. Stolen bases are also important as you can only steal in our games up to as often, and with as much chance of success, as in the majors.
Fielding
A fielder's actual number of errors each week in the majors determines his chances of making an error in Scoresheet. If a player is playing a different position in the majors than that for your Scoresheet team, we compare the number of errors he is making to the average number a player makes at that position. Then we use that ratio to decide how many errors he should make for you, given that you are playing him at a position at which he qualifies (if he does not qualify there he will get a large error penalty.) For example, if Moises Alou is traded to the AL, and starts playing DH, you could still play him in the OF. He'd make an average number of errors for an outfielder for your Scoresheet team (since he qualifies in the outfield), even though he is making no errors as a real life DH. We have this rule so that you don't get an unfair advantage, or get unfairly penalized, if you play a player at a position at which he qualifies in Scoresheet, while he plays a different position in the majors.
