Murtagh played with his brother once in a Pro40 game for Surrey
Middlesex bowler Tim Murtagh is looking forward to the chance to bowl younger brother Chris out when they face Surrey in the Pro40 League on Sunday.
The elder sibling, 27, moved to Middlesex from rivals Surrey in 2007.
He told BBC London 94.9: "I [played against him] in the Twenty20 but he ran himself out. I've never bowled to him.
"I'll bowl a couple of balls to his legs to get him off the mark, then get him out and have a massive celebration right in front of his face."
Chris, 24, has only played once alongside his brother in a Pro40 game before Tim left Surrey for their London rivals.
