MLB teams saw a slight increase in attendance during the regular season, averaging 30,366 fans per game. The Phillies led all of baseball with an average attendance of 45,441, followed by the Yankees, whose 45,107 average was down 3% from last season. The Red Sox and Phillies were the only teams to fill their stadiums to 100% capacity for the season. The Indians and Pirates, two surprise early season contenders, saw the largest attendance gains. The Indians' 22,726 fans per game was an increase of 30.3% over last year, while the Pirates' 24,255 average mark was up 21.8% from last season. The Dodgers, riddled with off-the-field issues, saw the biggest decline in attendance, down 17.7%. Meanwhile, the Rays, despite their improbable run to win the AL Wild Card, saw a 17% drop in attendance at Tropicana Field. Listed below is MLB regular season attendance with comparisons to last year.

NOTES: Teams can exceed 100% capacity because of standing-room-only tickets. All attendance figures are based on totals posted immediately following games. Figures may not reflect any subsequent adjustments made by teams or leagues.
AROUND THE HORN: The Twins' final attendance was the second most in team history, following the '10 season. This was the team's second season playing at Target Field (Twins)....The White Sox reached the 2 million attendance mark "for the sixth straight season" (CHICAGO SUN-TIMES, 9/29)....It is the "first time since moving into Safeco Field the Mariners have failed to draw 2 million fans." The last time the team drew fewer than 2 million in a full 81-game home schedule was '89 (AP, 9/28)....The Astros' final attendance was their "lowest since 1997, when they were in the Astrodome." The team's 56-106 record was worst in MLB (CHRON.com, 9/29).
