Indians encourage fans to 'show their Tribe pride'

The Indians are trying to create a playoff atmosphere in Cleveland, and not just at the ballpark.

The club is encouraging fans to "show their Tribe pride" on Thursday by wearing Indians gear to work and class, according to a club news release. Entering Wednesday a half-game behind Texas and Tampa Bay in the crowded American League Wild Card race, Cleveland returns home Thursday for four games against Houston and two against the White Sox.

The Indians are also inviting fans wearing Tribe gear at their offices and schools to tweet pictures to @Indians using the hashtag #TribeTown. The team will retweet and share those photos with its followers.

According to the team, a limited supply of $10 upper bleacher tickets remain available for most of the Indians' six remaining home games. The Indians entered Wednesday ranking 28th in the Majors in attendance this year, drawing an average of 19,435 fans per home game -- more than only Miami (19,267) and Tampa Bay (18,553).

The Indians are seeking their first postseason appearance since 2007, and several players have noted how much of an impact their fans can make down the stretch.

"That extra man is a good push to have," center fielder Michael Bourn said recently. "It gets your blood flowing a little bit. ... We try to give them a good show every time they come out."
