Wood bats. Woolen pants. Ninety percent humidity. Old timey baseball took over the Navy Yard this past weekend, as nearly 16 clubs from around the country convened in Philadelphia for a weekend exhibition stick-and-ball tournament, hosted by the Philadelphia Athletics Athletic Base Ball Club of Philadelphia.

The “monetarily self-sustaining” event was played under the rules and customs of 19th-century Base Ball (two words) and was sponsored by the likes of Shibe Vintage Sports, Mike’s BBQ and Franklin Fountain.

Photographer Dennis Tuttle was at the event — he’s now a huge fan of the Franklin Fountain ice cream, and the local nine’s pitcher (and Franklin Fountain owner) Ryan Berley — and shared some shots with Billy Penn. Here’s a look at the old-time fun.

The tournament featured teams like the New York Mutuals, the Diamond State Vintage Base Ball Club, Colorado Territorial All-Stars, Hoboken Nine and, pictured above, a member of the Keystone Base Ball Club of Harrisburg.

I’ve watched a lot of baseball. I did not know ‘Base Ball’ used underhand pitchers.

More sports should employ rolled up sleeves.

It’s hard to know what’s going on there, but it looks rather painful.

Old-timey, indeed.

Please tell me after some hard swinging base ball, the teams took a break to cool off with sarsaparilla.

Are they waving to the crowd or merely stretching their waving arms?

I’m not sure what to say about this photo, other than no member of the Phillies has looked this cool in the on-deck circle in at least 10 years.

Even the fans got into the garb of the era. Or this could be the commissioner. It’s hard to know.

Last, the fun wasn’t just at the plate. Here a base baller shows off his bat skills. Look, ma! No hands. But a bib! And wool pants!
