With the season entering its stretch run, Orioles manager Buck Showalter said the visit allowed his team to stay loose, something he's aimed to do with all of his clubs.

"I think everybody does," Showalter said. "Everything's so serious. There's so much during the game and what have you, before and after. ... Every clubhouse has something like that. I've had it like that for years. It's a players clubhouse. It's not mine. It's a place I want them to feel they want to come to."

Playoff ticket invoices sent

The Orioles will be mailing out invoices for postseason tickets to all season-ticket holders Friday.

The club entered Wednesday's game 5½ games out of the American League East lead and 3½ games behind the second AL wild-card spot. But this it usually the time teams send out invoices for playoff tickets in order to provide enough lead time to process orders, said Greg Bader, the Orioles' vice president of communications and marketing.

Season-ticket holders can guarantee seats for all 11 possible home playoff games (four World Series games, four league championship series games and either three division series games or one wild-card game and two division series games). The deadline for orders from season-ticket holders is Sept. 6.

Single game playoff tickets will go on sale to the general public later in September, Bader said.

Full-season and 29-game plan holders can save roughly 50 percent from the individual postseason ticket prices. The cost is also 20 percent cheaper than regular season individual prime game prices.
