Nationals outfielder Denard Span has been to (and played in) all 30 current major league parks. Span, who spent the first five years of his career in the American League with the Minnesota Twins, checked No. 30 off his list this week when the Nationals traveled to Houston.

The list of Nationals who have accomplished this feat is shorter than you might think, with Span joining Rafael Soriano and Nate McLouth in the All-30 Club. That’s it.

Ryan Zimmerman has yet to play at Minnesota’s Target Field, Seattle’s Safeco Field and Oakland’s O.co Coliseum. Jayson Werth and Scott Hairston have yet to play at Target Field. Adam LaRoche has yet to play at Target Field and the new Yankee Stadium. Kevin Frandsen has yet to play at Oriole Park at Camden Yards and Toronto’s Rogers Centre. Gio Gonzalez, who has yet to pitch at Arizona’s Chase Field, could join the club later this month.

Hover over the interactive map below to see how Span — and his team — fared in his first game at each park.

I’ve been to 21 of 30 current major league parks. I’m still missing Chicago (Wrigley Field), Cincinnati, Milwaukee, Miami, Minnesota, New York (Yankee Stadium and Citi Field), St. Louis and Seattle. My top 5:

1. Oriole Park at Camden Yards – Baltimore
2. PNC Park – Pittsburgh
3. AT&T Park – San Francisco
4. Coors Field – Colorado
5. Petco Park – San Diego
