Mark the date. The first do-or-die, one-game, wild card playoffs in Major League League history will take place on Oct. 5, with a nationally televised doubleheader on TBS. Commissioner Bud Selig made the announcement Thursday after the owners' meetings had wrapped up at MLB's Park Avenue headquarters in Manhattan.

In other playoff developments, Selig said the owners also had approved the first-round 2-3 format for this season only, with home-field advantage attached to the back end of the series. But that is likely to change for 2013.

"It's just for this year," Selig said. "Next year we'll have a different schedule."

Selig touched on a number of different topics during Thursday's news conference, from the possible relocation of the Athletics' franchise to the viability of the Rays' home in St. Petersburg to interleague play. While Selig was hesitant to delve into the A's-Giants feud over territorial rights for San Jose, the commissioner did suggest the Rays' current situation at Tropicana Field is growing untenable.

"They're operating the franchise, and they're doing beautifully in the field, obviously," Selig said. "But as I've said to Stu [Sternberg] many times, he and I are going to have conversations about it, because they're playing great, and he's going to have to let me know what he thinks they should do, and when they should do it, and how they should do it."

As for interleague play, which begins Friday, Selig said he remains a big fan of it, but the Astros' move to the American League next year will complicate matters. By how much hasn't been determined.

"We haven't made that decision," Selig said.
