A peer-reviewed article is published in a peer-reviewed journal only after it has been subjected to multiple critiques by scholars in that field. Peer-reviewed journals follow this procedure to make sure that published articles reflect solid scholarship and advance the state of knowledge in a discipline.
In baseball, a walk-off home run is a home run that ends the game. It must be a home run that gives the home team the lead (and consequently, the win) in the bottom of the final inning of the game. Thus the home team can walk off the field immediately afterward, rather than finishing the inning. The winning runs must still be counted at home plate.
On Base Percentage (OBP) - On Base Percentage is similar to batting average but includes appearances which led to walks and times a hitter was hit by a pitch. It is calculated by adding Base Hits, Bases on Balls and Hit by Pitches, and dividing by the sum of At Bats, Bases on Balls, Hit by Pitches and Sacrifices.ases on Balls (BB) - The number of bases on balls (walks) issued by the pitcher. This does not include Intentional Bases on Balls (where the manager effectively instructs the pitcher to walk a batter for tactical reasons).
