How to watch the MLB All-Star Game: TV, schedule and lineups

Nearly 50 years ago, a crew of All-Stars were supposed to line the field at the old RFK Stadium in Washington on a midsummer night for a game of baseball. Instead, there was only one major player on the grass: rain.

Water pelted the District, transforming the field into a soggy, unplayable, mucky carpet. Streams of rain gushed down the steps into the dugouts, flooding them.

That 1969 MLB All-Star game was eventually played the next day. Cincinnati Reds catcher Johnny Bench hit a home run, and San Francisco Giants first baseman Willie McCovey hammered two, handing the National League the year's crown.

Now, after a lengthy stretch of dry midsummer classics, there's rain threatening game play again.

Don't let the blue skies in Maryland fool you: Storm clouds are predicted to gather about 2 p.m. Tuesday, carrying scattered thunderstorms with them.

The rain is expected to taper off around the 8 p.m. first pitch, but there's still the question of Nationals Park's condition then, as well as the state of pregame activities. In 1990, the Chicago Cubs handled similar inclement weather by simply postponing the game an hour.

In the meantime, Orioles fans should steel themselves for what could be the last night that shortstop Manny Machado wears an Orioles cap. Other former Orioles in Washington include Seattle Mariners outfielder Nelson Cruz and Atlanta Braves outfielder Nick Markakis, who's making his All-Star Game debut. Milwaukee Brewers pitcher Josh Hader (Old Mill) is also a former Orioles minor leaguer.
