Jamie, 29, and his doubles partner John Peers from Australia go head to head with Julien Rojer and Horia Tecau on Centre Court for the men’s doubles crown.
Younger brother Andy was yesterday blown away by SW19 legend Roger Federer in three sets in the men’s singles semi-finals, preventing a dream Murray singles and doubles finals appearance.
Tennis fans will also be treated to the women’s singles final today, which pits 20-time Grand Slam winner Serena Williams against Spain’s Garbine Muguruza.
If Andy had gone through it would have been the first time brothers had been in the finals of the singles and doubles at the same Wimbledon for 109 years.
Asked after his crushing defeat to Federer if he would be in the stands to watch Jamie, Andy said: "I may come and be here and see what the score is.
"If it's close to finishing, I'll maybe try to go out and watch the last game or two.
"But I find it very, very difficult watching. I would love to but I get extremely nervous.
"I'll maybe ask Jamie if he would like me to come, if he feels like he would rather I wasn't there or I was there. I'll see what he wants."
In the women’s final, 33-year-old Williams will be seeking to hold all four Grand Slams with a sixth win at Wimbledon.
But 6ft world number 20 Muguruza, who was born in Venezuela and lives in Barcelona, has impressed against Angelique Kerber, Caroline Wozniacki and Agnieszka Radwanska to get to the final.
The 21-year-old said she is confident she can beat Williams - despite previous doubts over how the Spaniard would perform on grass – and if she does a star will be born.
Should Williams win she will move within one of Steffi Graff’s record of 22 major women’s titles.
World number one Novak Djokovic will try to prevent Federer from winning a record eighth Wimbledon title tomorrow.
