Sports blogs and sports sites that follow baseball closely have been posting photos and videos showing unruly, drunk and obnoxious Blue Jays fans.

One Yahoo sports blog displays several examples under the headline: “Toronto Blue Jays lead the league in drunken fans.”

Former Blue Jay catcher and current baseball analyst Gregg Zaun has also chimed in, suggesting some Jays’ fans are engaging in boorish, obnoxious behaviour that he finds appalling.

Other sports media sites are taking notice too.

The sports site Deadspin.com has posted a video showing a Blue Jays fan vomiting after trying to leave the stadium.

Boorish behaviour at Blue Jays games has risen to alarming levels, according to Zaun.

The fans, especially in the 500 level, “are developing a reputation,” Zaun told the Star on Monday.

“It’s very, very prevalent at the Rogers Centre, especially in the later innings when the Jays are losing that people lose their minds,” Zaun said.

He said some fans are under the wrong impression that just because they paid their admission that they can behave anyway they want.

“They’re getting drunker, and drunker and drunker and it’s because fans are getting younger and younger,” Zaun said.

He added he is most concerned about fans throwing objects onto the field, but he doesn’t even think “profanity should be tolerated at all.”

The former Blue Jays catcher said offensive behaviour on social media sites is carrying over to ball games, fuelled by alcohol, even though the club shuts off the taps at the end of the seventh inning.

Some fans are being accused of tossing beer, peanuts and paper airplanes onto the playing field.

“As a player who played for 16 years, anytime I saw a fan throw something onto the field, I got them ejected,” Zaun said. “I pointed them out to security.”

Zaun said he is surprised there is so much drinking among the younger fans because prices are not cheap.

“It doesn’t surprise me at all that this (latest incident) happened at the Rogers Centre because I’ve noticed over the years they are getting drunker and drunker with more bravado each year. Unbelievable.”

Blue Jays spokesman Jay Stenhouse would not comment on any blog postings or the behaviour of Jays fans in comparison with the league’s other fans because there is no evidence to back up this claim.

“We are not going to respond to a blog post about our fans in relation to all other fans based upon a blog site,” he wrote in an email. “I have not seen any reliable survey that documents fan conduct around baseball.”

Another incident happened Friday, and this time it was the New York Yankee security guards who got involved, leading to the ejection of two fans.

The security guards, who travelled with the team to Toronto, pointed out and requested the ejection of a pair of Blue Jays fans.

Those fans were heckling the Yankee bullpen, according to a ticket holder in the section, who says Toronto police and Rogers Centre security complied with the request.

Toronto police say the decision on ejections rests with Rogers Centre security.

One of the Yankee guards, Mark Kafalas, told the Star the fans were not only heckling, but throwing peanuts into the Yankees bullpen as well.

He added that later in the game someone threw a full beer from the second deck.

The Blue Jays have strict ground rules for fan behaviour.

Fans who are abusive in language or gestures can be removed.
