Setting the Trends: Houston, we have options

Astros, Astros everywhere!

Houston seems to be the hot-spot for Fantasy treasure hunting this week, as owners have flocked to the Astros' outfield to shore up their teams, welcoming Jordan Schafer and J.D. Martinez to a combined 70 percent higher ownership level.

Most Added Players (as of 4/17)
Player % change
1. Jordan Schafer, OF, Astros 41
2. Lance Lynn, RP, Cardinals 32
3. Santiago Casilla, RP, Giants 31
4. J.D. Martinez, OF, Astros 29
5. Barry Zito, SP, Giants 29
6. Danny Duffy, SP, Royals 28
7. Kyle Drabek, SP, Blue Jays 28
8. Omar Infante, 2B, Marlins 27
9. Adam LaRoche, 1B, Nationals 25
10. Fernando Rodney, RP, Rays 25

If you missed the Martinez train, it might already be too late to jump on board -- he's now owned in 91 percent of leagues. But Schafer, who offers a little more speed than his fellow outfield counterpart, is still available in just under half. And this is the beauty of Roster Trends: using data from other leagues to try and beat people in your own league. It's the circle of life, just like in The Lion King. But with far less subliminally sexual messaging.

On to the highlights!

Most Added Players (complete list)

Jordan Schafer, OF, Astros
Jump in ownership: 41 percent (from 13 percent to 54)
Reason for the jump: Possibly fulfilling his potential
Why you should join the crowd: Schafer had bushels of promise while coming up in the Atlanta farm system but fizzled in his time with the big club, partially thanks to hand and finger injuries, and partially just to what seemed to be unrealized potential. He was shipped to Houston as part of the Michael Bourn deal and is now playing every day in the Astros outfield. He already has five steals on the season.
Devil's advocate: Schafer's career minor league batting totals aren't that impressive -- he has a .260 average over 500-plus games. And while he's often regarded as a speedster, his ceiling is more along the lines of 35 stolen bases, as opposed to 55.

Lance Lynn, RP, Cardinals
Jump in ownership: 32 percent (from 37 percent to 69)
Reason for the jump: He's 2-0 with a 1.50 ERA and 0.75 WHIP so far this season
Why you should join the crowd: Lynn, 24, a former first-round draft pick for St. Louis, has progressed nicely through the minors. He debuted with the Cardinals in 2011, posting a 3.12 ERA in 34 2/3 innings as mainly a reliever. He doesn't strike out a batter per inning, but he's close. Adding to his value is the fact that Chris Carpenter's return is still pretty unclear, meaning even if Lynn is the odd man out when Carpenter comes back, that day may still be a while away.
Devil's advocate: Lynn had a 1.33 WHIP in the minors and while that's not bad, it's not exactly a sign pointing to him as a future superstar. He's also going to be in a bit of a crunch when Chris Carpenter returns, sitting behind Jaime Garcia and Jake Westbrook in the rotation.

Less than 50, more than 50
Players owned in less than 50% of leagues who should be owned in more than 50%
Player % owned
1. Bryan LaHair, OF, Cubs 49
2. Denard Span, OF, Twins 40
3. Brad Lidge, RP, Nationals 36
4. Eric Thames, OF, Blue Jays 35
5. David Murphy, OF, Rangers 29

J.D. Martinez, OF, Astros
Jump in ownership: 29 percent (from 62 percent to 91)
Reason for the jump: Martinez is batting .333 with three home runs and 10 RBI so far this season
Why you should join the crowd: Martinez had a somewhat inauspicious debut, replacing Hunter Pence for the Astros in 2011, hitting six home runs in 208 at-bats, while batting .274. But he carried a .342 batting average in 1,118 minor league at-bats with a .958 OPS.
Devil's advocate: I'm not really sure there is a rock solid one. Granted, 91 percent ownership is pretty high for a player with just under 250 career at-bats, but as long as a team isn't angling to have Martinez as a Ryan Braun-type contributor and is more realistic about a ceiling of 25 home runs and a .300-.320 average, he's a smart add.

Santiago Casilla/Sergio Romo, RPs, Giants
Jump in ownership: Casilla: 31 percent (from one percent to 32); Romo: 22 percent (from 17 percent to 39)
Reason for the jump: Giants closer Brian Wilson is likely out for the year with an elbow injury
How you should join the crowd: Carefully. It isn't clear whether Romo or Casilla will be the closer in Wilson's absence just yet. And even if Romo gets the first save, there's a chance Casilla gets the second, and they rotate in a maddening dance to irrelevancy for both. However, in a worst-case scenario, picking one of these two up still gives you a capable, high-strikeout, low-ERA and WHIP middle reliever. Personally, I lean Romo and think that he'll get the most opportunities. But there's enough support for Casilla to at least consider the less-enjoyable possibilities.
Devil's advocate: Not many owners can afford to pick up both Romo and Casilla -- which would be the preferred route as the situation plays itself out -- so on top of the fear of choosing the wrong one, there is the chance that they have a committee, which essentially makes both pitchers "the wrong one." If it's a casual pickup, fine. But consider the downside carefully before using top waiver priority on a pitcher who may essentially turn out to be a 12-save maximum middle reliever.
