In baseball statistics, the term times on base, also abbreviated as TOB, is the cumulative total number of times a batter has reached base as a result of hits, walks, and hit by pitches. This statistic does not include times reaching first by way of error, dropped third strike, fielder's obstruction, or a fielder's choice, making this statistic somewhat of a misnomer.

Baseball statistics include a variety of metrics used to evaluate player and team performance in the sport of baseball.
In baseball, an at bat (AB) or time at bat is a batter's turn batting against a pitcher. An at bat is different from a plate appearance. A batter is credited with a plate appearance regardless of what happens during their turn at bat, but a batter is charged with an at bat only if that plate appearance does not have one of the results enumerated below. While at bats are used to calculate certain statistics, including batting average and slugging percentage, a player can qualify for the season-ending rankings in these categories only if they accumulate 502 plate appearances during the season.
In baseball statistics, a hit, also called a base hit, is credited to a batter when the batter safely reaches or passes first base after hitting the ball into fair territory with neither the benefit of an error nor a fielder's choice.
In baseball statistics, on-base percentage (OBP) measures how frequently a batter reaches base. An official Major League Baseball (MLB) statistic since 1984, it is sometimes referred to as on-base average (OBA), as it is rarely presented as a true percentage.
In baseball, a player is credited with a plate appearance each time he completes a turn batting. Under Rule 5.04(c) of the Official Baseball Rules, a player completes a turn batting when he is put out or becomes a runner. This happens when he strikes out or is declared out before reaching first base; or when he reaches first base safely or is awarded first base ; or when he hits a fair ball which causes a preceding runner to be put out for the third out before he himself is put out or reaches first base safely. A very similar baseball statistic, at bats, counts a subset of plate appearances that end under certain circumstances.
James Edward Rice is an American former professional baseball left fielder and designated hitter who played in Major League Baseball (MLB). Rice played his entire 16-year MLB career for the Boston Red Sox. In 2009, Rice was inducted into the Baseball Hall of Fame.
In baseball, a double is the act of a batter striking the pitched ball and safely reaching second base without being called out by the umpire, without the benefit of a fielder's misplay or another runner being put out on a fielder's choice. A double is a type of hit and is sometimes called a "two-bagger" or "two-base hit". For statistical and scorekeeping purposes it is denoted by 2B.
In baseball, a triple is the act of a batter safely reaching third base after hitting the ball, with neither the benefit of a fielder's misplay nor another runner being put out on a fielder's choice. A triple is sometimes called a "three-bagger" or "three-base hit". For statistical and scorekeeping purposes it is denoted by 3B.
In baseball and softball statistics, an error is an act, in the judgment of the official scorer, of a fielder misplaying a ball in a manner that allows a batter or baserunner to advance one or more bases or allows a plate appearance to continue after the batter should have been put out. The term error is sometimes used to refer to the play during which an error was committed.
