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 March 29, 2024, no active players are in the top 100 for career total bases. The active leader is current free agent Joey Votto in 133rd with 3,706.

In baseball statistics, slugging percentage (SLG) is a measure of the batting productivity of a hitter. It is calculated as total bases divided by at-bats, through the following formula, where AB is the number of at-bats for a given player, and 1B, 2B, 3B, and HR are the number of singles, doubles, triples, and home runs, respectively:
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.
Shawn David Green is an American former Major League Baseball right fielder. 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 single-season record in home runs. Green was also in the top five in the league in home runs, RBIs, intentional walks, and MVP voting.
Craig Alan Biggio is an American former baseball second baseman, outfielder and catcher who played 20 seasons in Major League Baseball for the Houston Astros, from 1988 to 2007. A seven-time National League (NL) All-Star often regarded as the greatest all-around player in Astros history, he is the only player ever to be named an All-Star and to be awarded Silver Slugger Award at both catcher and second base. With longtime teammates Jeff Bagwell and Lance Berkman, he formed the core of the "Killer B's" who led Houston to six playoff appearances from 1997 to 2005, culminating in the franchise's first World Series appearance in 2005. At the end of his career, he ranked sixth in NL history in games played (2,850), fifth in at bats (10,876), 21st in hits (3,060), and seventh in runs scored (1,844). His 668 career doubles ranked sixth in major league history, and are the second-most ever by a right-handed hitter; his 56 doubles in 1999 were the most in the major leagues in 63 years.
Secondary average, or SecA, is a baseball statistic that measures the sum of extra bases gained on hits, walks, and stolen bases depicted per at bat. Created by Bill James, it is a sabermetric measurement of hitting performance that seeks to evaluate the number of bases a player gained independent of batting average. Unlike batting average, which is a simple ratio of base hits to at bats, secondary average accounts for power, plate discipline (walks), and speed. Secondary averages have a higher variance than batting averages.
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 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.
