Some of Baltimore and Washington's boys of summer are taking a swing at saving the Chesapeake Bay.

MASN, the television network that broadcasts Baltimore Orioles and Washington Nationals baseball games, announced today (6/25) that it is launching a “Go to Bat for the Bay” public service campaign with the Chesapeake Bay Foundation.

Among the players featured in the spots are Orioles outfielder Adam Jones and pitcher Jeremy Guthrie, who tells viewers, "“A cleaner bay means better seafood and more jobs for those who bring the Chesapeake's bounty to our dinner tables.”

In another spot seen above, the Nats' Adam Dunn touts recycling oyster shells in addition to paper and plastic.

The spots will be aired on MASN, whose seven-state broadcast territory overlaps with the six-state bay watershed. About 175,000 viewers tune in when Orioles and Nationals games are on.

Foundation president Will Baker says the public-service ads "help CBF enhance awareness and educate millions of sports fans who live in the Chesapeake region."

Here's hoping the players have better luck pitching bay preservation than they've had lately in their regular jobs. For more, go here.
