Baseball Basics: How to Keep Score
Different fans have different methods of keeping a scorecard, and many use their own notations.
But here's a simple method:
If the hitter grounds out to shortstop, for example, write in "6-3," which shows the shortstop threw him out at first base. If the hitter flies out to left field, write a "7."
If the batter gets a hit, write in the hit according to which base he reached. Each corner of the box represents a base, with the lower-right corner being first.
If he singles, put a "-" in the lower right. If he doubles, write a "=" in the upper right, and so on. For a walk, use "BB" in the lower right. As the runner advances, mark the appropriate symbol in the appropriate corner.
If a runner scores, put a circle at the bottom of the box, and inside the circle put the symbol of the play and/or the player that drove him in. For example, if the No. 5 hitter drives in two runs with a single, mark his single in the bottom right of his box and mark a circle with the number "5" in it in the boxes of the runners who score (Some people like to use uniform numbers here, so you can tell who did what, even after lineup changes).
At the end of each inning, total the hits and runs for that inning only. At the end of the game you'll be able to add the innings total to get the game score.

Baseball Basics: Stats 101
Batting Average (AVG): Divide the number of base hits by the total number of at bats. | If Tony Gwynn has 600 at bats and has 206 hits. His batting average would be .343 (206/600) |
Earned Run Average (ERA): Multiply the total number of earned runs by nine, and divide the results by the total innings pitched. | Randy Johnson has allowed 67 runs in 220 innings. Multiply 67 by 9: 67x9=603. Divide 603 by 220 (his innings pitched): 603/220=2.74 -- which is his ERA |
W-L percentage: Divide the number of games won by the total number of decisions. | Pedro Martinez has a 16-3 record, Divide his win total(16) by his total number of decisions: (19):16/19=0.842 |
Slugging Percentage (SLG): Divide the total number of bases of all base hits by the total number of times at bat | Sammy Sosa has 282 total bases and 440 at-bats. Divide 282 by 440 to get his slugging percentage: 282/440=.641 |
On-Base Percentage (OBP): Divide the total number of hits plus Bases on Balls plus hits by Pitch BY at Bats plus Bases on Balls plus hit by Pitch plus Sacrifice Flies | In Derek Jeter's 434 at-bats, he has 152 hits, 59 walks, has been hit by 9 pitches, and he's hit 6 sacrifice flies. So here's the formula to determine his OBP: (152+59+9)/(434+59+9+6)=220/508=.433 |
Fielding Average: Divide the total number of putouts and assists by the total number of putouts, assists and errors. | Edgardo Alfonzo has 218 putouts and 290 assists, while committing only 2 errors. So his fielding percentage is: (218+290)/(218+290+2)=508/510=.996 |
Magic Numbers: Determine the number of games yet to be played, add one, then subtract the number of games ahead in the loss column of the standings from the closest opponent. | Texas is 7 games ahead, with 50 games remaining. So here's Texas' magic number: |
