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.
Baseball (1-2 players): Grip the controller like a bat and swat fastballs out of the park in a home run derby. Timing and bat speed will make all the difference between going yard and whiffing, so keep an eye on the ball and swing for the fences. In the two-player game, one player pitches and the other bats.
