Jon Gray proves you have to be patient with preseason sleepers. Coming off a long stint pitching his home games in the thin air of Colorado, Gray didn't set the league on fire in his first two months with Texas, and impatient fantasy managers largely moved on, leaving Gray available in over half of CBS leagues a little over a month ago. But he was outstanding in June, going 3-1 with a 2.39 ERA, 1.01 WHIP and 44:12 K:BB ratio in 37 2/3 innings over six starts, with half of his earned runs allowed coming in a single poor outing early in the month. He's back up to 80% rostered now, so you won't find him in our list of waiver wire options below, but if he's somehow still available in your league, don't wait any longer to add him.

Before you determine which players you should target on the Fantasy baseball waiver wire ahead of Week 14, you NEED to see what R.J. White has to say.

If you're a regular subscriber to SportsLine, you probably know White from dominating NFL picks for years, but did you know he actually got his start in sports media as a fantasy baseball analyst? He even finished No. 1 among all experts for his draft rankings the first year FantasyPros tracked MLB expert accuracy on their site. White has continued to excel at season-long and dynasty Fantasy baseball formats, and this year he's sharing his Fantasy baseball expertise with SportsLine subscribers.

Now, he's revealed the best widely available free agents ahead of Week 14. One player to target on the Week 14 waiver wire: Royals first base prospect Vinnie Pasquantino, who is "obviously up for the long term, so stick with him and expect a lot of contact, a high OBP and solid power the rest of the way," White says.

White is also all-in on a barely rostered reliever with MASSIVE upside! You ABSOLUTELY need to see who it is before making any Week 14 waiver wire claims.

So which starting pitchers are worth scooping off the waiver wires in all leagues? And which widely-available players at each position are options to consider in deeper leagues? ...
