In baseball statistics, total bases (TB) is the number of bases a player has gained with hits. It is a weighted sum for which the weight value is 1 for a single, 2 for a double, 3 for a triple, and 4 for a home run. Only bases attained from hits count toward this total. Reaching base by other means (such as a base on balls) or advancing further after the hit (such as when a subsequent batter gets a hit) does not increase the player's total bases.
The total bases divided by the number of at bats is the player's slugging average.
Hank Aaron is the career leader in total bases with 6,856. Albert Pujols (6,211), Stan Musial (6,134), and Willie Mays (6,080) are the only other players with at least 6,000 career total bases.
As of September 26, 2024, no active players are in the top 100 for career total bases. The active leader is Los Angeles Dodgers first baseman Freddie Freeman, tied in 109th with 3,866.

On-base plus slugging (OPS) is a sabermetric baseball statistic calculated as the sum of a player's on-base percentage and slugging percentage. The ability of a player both to get on base and to hit for power, two important offensive skills, are represented. An OPS of .800 or higher in Major League Baseball puts the player in the upper echelon of hitters. Typically, the league leader in OPS will score near, and sometimes above, the 1.000 mark.
Henry Louis Aaron, nicknamed "Hammer" or "Hammerin' Hank", was an American professional baseball right fielder who played 23 seasons in Major League Baseball (MLB), from 1954 through 1976. Considered one of the greatest baseball players in history, he spent 21 seasons with the Milwaukee / Atlanta Braves in the National League (NL) and two seasons with the Milwaukee Brewers in the American League (AL). At the time of his retirement, Aaron held most of the game's key career power-hitting records. He broke the long-standing MLB record for career home runs held by Babe Ruth and remained the career leader for 33 years, until Barry Bonds surpassed his famous total of 755 in 2007. He hit 24 or more home runs every year from 1955 through 1973 and is one of only two players to hit 30 or more home runs in a season at least fifteen times.
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. He was inducted into the Baseball Hall of Fame in 2009.
Robin R. Yount, nicknamed "the Kid" and "Rockin' Robin", is an American former professional baseball player. He spent his entire 20-year career in Major League Baseball as a shortstop and center fielder for the Milwaukee Brewers (1974–93).
Shawn David Green is an American former professional baseball right fielder who played for multiple teams in Major League Baseball (MLB). Green was a first-round draft pick and a two-time major league All-Star. He drove in 100 runs four times and scored 100 runs four times, hit 40 or more home runs three times, led the league in doubles, extra base hits, and total bases, won both a Gold Glove Award and a Silver Slugger Award, and set the Dodgers then single-season record in home runs. Green also set the MLB record for most total bases in a single game, with 19, on May 23, 2002 vs. the Milwaukee Brewers. Green was in the top five in the league in home runs, RBIs, intentional walks, and MVP voting multiple times throughout his career.
In baseball, an extra-base hit, also known as a long hit, is any base hit on which the batter is able to advance past first base without the benefit of a fielder either committing an error or opting to make a throw to retire another base runner. Extra-base hits are often not listed separately in tables of baseball statistics, but are easily determined by calculating the sum total of a batter's doubles, triples, and home runs. Extra-base hits are particularly valuable because they ensure that there will be no runners on base that will be forced to advance on the next fair ball.
Todd Lynn Helton is an American former professional baseball first baseman who played his entire 17-year career for the Colorado Rockies of Major League Baseball (MLB). A five-time All-Star, four-time Silver Slugger, and three-time Gold Glove Award winner, Helton holds the Rockies' club records for hits (2,519), home runs (369), doubles (592), walks (1,335), runs scored (1,401), runs batted in, games played (2,247), and total bases (4,292), among others.
In baseball, batting average (BA) is determined by dividing a player's hits by their total at-bats. It is usually rounded to three decimal places and read without the decimal: A player with a batting average of .300 is "batting three hundred". If necessary to break ties, batting averages could be taken beyond the .001 measurement. In this context, .001 is considered a "point", such that a .235 batter is five points higher than a .230 batter.
In baseball statistics, total bases is the number of bases a player gains with hits. It is a weighted sum with values of 1 for a single, 2 for a double, 3 for a triple and 4 for a home run. For example, three singles is three total bases, while a double and a home run is six total bases.
