Baseball stats?

Question

I have recently really got in to baseball, thanks to my nocturnal baby and Setanta.

I cant get a grip on the stats. What does RBI, ERA mean for example?

Answer 2

RBI stands for runs batted in, which is how many runs a batter knocks in. For instance, if a hitter gets a base hit that scores 2 runs, he would get credit for 2 RBI.

ERA stands for earned run average...basically how many earned runs a pitcher gives up per 9 innings of pitching. You figure it out by taking the number of earned runs, multiply it by 9, and then divide it by the number of innings pitched.

For instance, if a pitcher gives up 3 earned runs in 9 innings, you would take 3 x 9 =27, and divide it by 9 = 3, so the pitchers ERA is 3.00.

Answer 3

The main ones are listed (others can be found on the link below)

Offense:
AB- At Bat
H- Hits
HR- Homeruns
RBI- Runs Batted In (runs knocked by a player)
SB- Stolen Bases
BB- Walks (base on balls)
K- Strikeouts
OBP- On Base Percentage (% a player reaches base)
SLG- Slugging Percentage (total bases / at bats)
TB- Total Bases

Pitching:
W- Wins
L- Losses
SV- Saves
IP- Innings Pitched
CG- Complete Games
K- Strikeouts
BB- Walks
SO- Shutouts
ERA- Earned Run Average (runs allowed per 9 inning game)
WHIP- Walks and Hits / Innings Pitched

Answer 4

RBI is "Runs Batted In" and ERA is "Earned Run Average" for the pitchers. I hope the attached source will help you.

Answer 5

The player has a total of 40 hits. Out of those hits, 13 are doubles, 8 are triples and four are home runs. Those three categories (2B, 3B, HR) add up to 25. So the remainder of his hits are singles, and he would have 15 of those.

Answer 6

RBI runs batted in
ERA earned run average
