Nana celebrates her 100th birthday at Safeco Field

Barbara -- or “Nana,” as she's known to her five children, 18 grandchildren and 21 great-grandchildren -- celebrated her centennial birthday at Safeco Field on Saturday.

Eighty friends and family members made it out to the ballpark for the celebration, some coming from as far as Tanzania.

The whole stadium sang Happy Birthday between innings for Barbara, who also celebrated her 95th birthday at a Mariners game in 2007.
