I'd like to see Berendorff get a crack, we've lost two lefties he's the next best. Windies always struggle again left handed bowlers and a bloke with something to offer gets a run.
Yep, Behrendorff would be the go for me. Pattinson in for Siddle, Behrendorff in for Starc.
But honestly, any merkin will do who isn't Siddle. Jackson Bird, James Faulkner, Sean Abbott, Gurinder Sandhu, Nathan Coulter-Nile, Behrendorff...all of them will likely figure in a Test match or two at some point in future, even as a sixth choice if injuries demand so why not throw them in against a weaker side? Beats a bloke in his thirties who has never really done much with the ball and now bowls with all the pace of a fourth grader anyway
