Inside 'Green Monster' at Boston Red Sox's Fenway Park

10 September 2012 Last updated at 00:48 BST

Fenway Park, home of the Boston Red Sox, is the oldest venue in US Major League Baseball.

Throughout 2012 fans have been celebrating the ballpark's 100th birthday.

Baseball is known for its traditions - and at Fenway Park that's particularly true. The stadium still has a manual scoreboard which is operated inside a 37ft (11.2m) high wall called the "Green Monster".

Score keeper Christian Elias has been clattering metal numbers in there for 22 years. He spoke to the BBC about his job tracking the highs, and many lows, of the Boston Red Sox - one run at a time.
