Line opened at -200 and has dropped all the way to -165. He is 4-0 against Fognini, including thrashing him on clay earlier this year (3,0). Seppi looked good enough in his match today, while Fognini hasn't looked the greatest in his two matches - struggling to hold serve in nearly every game. I wanted to make a big bet on Seppi here, but the line change scares me. Should I be concerned?
