How To Figure Out Averages
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. What's his ERA? Multiply 67
by 9: 67x9=603. Divide 603 by 220 (his innings pitched): 603/220=2.74. That's
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, and has been hit by
9 pitches. He's hit 6 sacrifice flies. So here's the formula to determine his
on-base average:
(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. So here's Texas'
magic number:
Games remaining (50) +1=51. 51-7=44. The Rangers' magic number to clinch the
AL West is 44.
