Two homers in extra innings

Last night Granderson hit a homer in the 11th and then another in the 12th. That combination can't be very common. Anybody have an idea when was the last time someone hit solo homers in consecutive innings after the 9th?

In case anyone is interested, here is an answer I received from a fellow SABR member:

 

On August 12, 1966, Cincinnati's Art Shamsky homered in the 10th and
11th innings in a game at Crosley Field. This 10th-inning homer off
Pittsburgh's Elroy Face tied the game at 9-9, and his two-run homer in
the 11th re-tied the game at 11. Pittsburgh would eventually win, 14-11
in 13 innings.

 

Then, on June 4, 2013, Philadelphia's John Mayberry Jr. homered in the
10th & 11th innings at Citizens Bank Park. His 10th-inning homer off
Miami's SteveCishek, tied the game at 3-3, and Mayberry's grand slam in
the bottom of the 11th off Edgar Olmos won the game, 7-3, for Philadelphia.

 

Granderson is the first to hit solo homers in consecutive extra innings.
