In baseball, an extra-base hit (EB, EBH or XBH), 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 (see fielder's choice). 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.
Another related statistic of interest that can be calculated is "extra bases on long hits". A batter gets three of these for each home run, two for each triple, and one for each double. Thus, leading the league in "Most extra bases in long hits" is a significant accomplishment in power hitting.
