Watch: Andreas Seppi hits a stunning 'tweener at the Monte Carlo Masters

During his first-round win at the Monte Carlo Masters, Andreas Seppi hit one of the best 'tweeners we've seen since Roger Federer hit his stunner against Novak Djokovic at the 2009 U.S. Open. Seppi nailed everyone's favorite hot-dogging shot past No. 15 Mikhail Youzhny en route to his first top-20 victory of the season.
Seppi's rendition of this shot was so eye-popping because he wasn't going for the trick shot just to dazzle the crowd. The 'tweener was actually his only defensive option after chasing down a perfectly weighted lob by Youzhny. He struck it clean for a passing shot down the line, and and the ball barely clips the outside of the line. And by "barely" we do mean barely.
Watch the Italian's hot shot below.
