There have been 14 XFL games so far, and SportsLine expert R.J. White has nailed 13 of them. That's right -- he cashed both Saturday games, not to mention all four of his picks last week, to improve to 13-1 against the spread.

Not only is White on fire, he's often cashing with ease. Last Sunday for instance, White nailed the XFL doubleheader by a combined 49 points. He had St. Louis -9 (won 29-9) and Los Angeles +8 (won 39-9), and anyone who followed his bets never broke a sweat.

This is the same expert who twice recently cashed big in the world's most prestigious football handicapping tournament, the Westgate Las Vegas SuperContest.

Now, White has locked in strong plays for every Week 4 game. We can tell you he's backing the under (44.5) hitting when the Vipers vie for their first victory against the visiting Defenders. He's also targeting a line he knows is WAY OFF! You ABSOLUTELY need to see his picks before getting down on the XFL.
