I agree this loss is the lowest yet for DK. I think he is going the clay tournament route now. He's entered in the San Luis Potosi, Mexico Challenger (wk of 3/25) and the Blumenau, Brazil Challenger (wk of 4/8), which means he'll likely also enter the Brazil challengers on the wks of 4/15 and 4/22. Playing European challengers/futures last year helped him get his mojo back after a similar big slump. Hope this trip does the same.
