Major League Baseball yesterday announced that overall attendance this season set a record for the fourth consecutive year. The league reported total attendance of 76,215,082 through Sunday's games, up from 76,042,787 for all of last season. Average per-game attendance through Sunday is 32,710, an increase of about 4 percent over 2006 and 7.5 percent since 2004. That average would surpass the record of 31,423 in 1994 before a strike interrupted the season. Baseball executives cited a number of factors for the rise in attendance, including the addition of the wild card and interleague play, construction of new ballparks and increased competitive balance.
