| GP: Games the player appeared in, however briefly. | AB: At-bats: trips to the plate that ended in a hit, an out or an error. Walks and sacrifices are not counted. | R: Runs — scored by the batter, or allowed by the pitcher. | H: Times the batter reached base by hitting the ball, without help from an error. | HR: Home runs hit. | RBI: Runs that scored because of this batter's plate appearance. | SB: Bases taken while the pitcher was delivering. Being caught is counted separately. | AVG: Hits per at-bat. .300 is the traditional line between a good hitter and a great one. | OBP: Share of plate appearances that ended with the batter on base — hits, walks and hit-by-pitches. | SLG: Total bases per at-bat, so a home run counts four times a single. | OPS: On-base percentage plus slugging. Around .800 is All-Star level, .900 is MVP territory. | ||
