A's celebrate 1973 championship with an old-fashioned reunion

The A's celebrated the 40th anniversary of their 1973 World Series championship on Saturday, inviting members of that team to reunite and take the field with their 2013 counterparts.

The first 15,000 fans received Reggie Jackson bobbleheads and the Hall of Famer himself walked out to right field with Josh Reddick before throwing the ceremonial first pitch.

Here's Bob Melvin, Sal Bando and Josh Donaldson walking out to third base together

Reggie Jackson looks pretty good as a bobblehead

A great first pitch to former A's catcher Ray Fosse
