Less than two weeks into the MLB season, and we're already starting to see some major trends take place around the baseball world. 

In the American League, the Detroit Tigers and Los Angeles Angels are off to surprisingly hot starts. Meanwhile in the Senior Circuit, the Cincinnati Reds and Arizona Diamondbacks are doing damage. 

While we can't read a whole lot into team-wide success thus far this season, we surely can look at it from a fantasy standpoint and analyze some trends that might continue to take hold. 

Here are a look at the most-surprising fantasy hitters throughout the early part of the MLB season. 

Yunel Escobar, Third Base, Los Angeles Angels

Escobar has consistently been among the most underrated players in baseball over the past couple seasons. Back in 2015 with Washington, he hit .314 with a .375 OBP while posting nine homers and 56 RBI. Then, last year in his first season with the Angels, Escobar hit .300-plus with a solid .355 OBP. 

The issue here from a fantasy perspective of that Escobar plays at a position where we expect power. Having never hit more than 14 homers in a season, this has continually led to an issue with relevance from a fake baseball perspective. For Escobar to be productive in this manner, he would have to post a .320-plus average with an OBP nearing .400. 

Through the first nine games of this season, Escobar has done that and a whole heck of a lot more. He's hitting a whopping .455 with a .500 OBP and a tremendous 1.136 OPS. Having improved from the plate over the past several seasons, Escobar could be primed for an absolutely huge season from an average standpoint. If so, he becomes a tremendously relevant season-long and DFS option. 

Eugenio Suarez, Third Base, Cincinnati Reds

This still young infielder was a pleasant surprise for Cincinnati last season, putting up 21 homers, 70 RBI and 11 stolen bases. The issue here is that he hit just .248 with 155 strikeouts and a substandard .317 OBP. 

Thus far this season, none of that has been an issue. Now fully entrenched in the middle of Cincinnati's lineup, Suarez heads into Thursday's action with a .429 average and a .529 OBP. Equally as important, he has walked more times than he has struck out. Small sample size aside, that's a big deal. It also doesn't hurt that Suarez has put up two homers and eight RBI in nine games. That's the wow factor here. 

Welington Castillo, Catcher, Baltimore Orioles

Heading into this season, his first with Baltimore, Castillo was seen as a hitter with decent power but limited ability to produce much more than that from the plate. While he did have multiple double-digit homer seasons, Castillo ended the 2016 campaign as a career .253 hitter. 

Now in the more hitter-friendly American League east, Castillo has absolutely dominated from the plate thus far this season. Through six games, he boasts a .409 average, .435 OPB and .935 OPS. That's not too shabby at all.

And while he has yet to go yard in 22 at-bats, Baltimore will surely take a better average at the cost of power. After all, the team already has enough homers coming from the rest of its lineup. It remains to be seen whether Castillo can continue to produce anywhere near these numbers moving forward, but his move to the AL has seemingly worked out from a fantasy perspective. 

Khris Davis, Outfielder, Oakland Athletics

Sure Davis put up 42 homers with 102 RBI in his first season with the A's last year. Sure he leads the Majors in homers since the 2015 All-Star Break. That's all fine and dandy. But up until this season, the power hitter was seen as nothing more than one-dimensional. That's obviously changed nearly two weeks into the 2017 campaign. 

Through his first nine games, Davis is hitting a robust .353 with four homers, six RBI and eight runs scored. He's also posted a tremendous .395 OPB and 1.159 OPS. Davis is clearly comfortable hitting in the middle of Oakland's lineup. And it sure looks like he's taken to American League West pitching. 

Should Davis push his average to the mid .270s over the course of the season, he will surely become an elite-level fantasy performer. That's the biggest key here. Maintaining this level of excellence over the long run without falling back into the trap of striking out at a level fantasy owners are not comfortable with.
