Two future stars got the promotion in recent days and they have the ability to impact your season long team immediately. Now that we are almost a week and a half into the MLB season, seasonal owners are starting to get a rough idea of what his/her team(s) lacks and areas that need to be improved. This piece features some quality category producers, who are more or less under owned in fantasy circles. One of these guys could turn out to be that diamond in the rough that helps push your team along to start a nice winning streak. The name of the game is to grab as many categories as you can, and that involves grabbing some guys who are niche producers.

If you have any questions, hit me up on twitter. Let’s check out some players that are ready to impact some categories.

Jeremy Hazelbaker, OF STL— Hazelbaker has done nothing but hit for the Cardinals and as long as he is producing, expect him to remain hitting second in the lineup. Through seven games, Hazelbaker is 10-for-19 with five extra-hits, including two long balls. The 28-year-old has some impressive, and fantasy noteworthy, streaks going on including a six-game hit streak, and recording an RBI and scoring a run in five straight games. Obviously, he is going to regress at some point, but seeing as he hit .274 in 208 Triple-A games, the average might not drop too far in the twos. During that same span at Triple-A, Hazelbaker smacked 25 homers and stole 54 bases. Like many, Hazelbaker struggled with strikeouts at the minor league level, which creates some concern at the big league level. When pitchers adjust, he will hit some bumps, but he does enough otherwise and offers enough speed to maintain fantasy value. While he is hot, go ahead and pick him up, especially if you’re in an NL-only league or a deeper mixed format.

Cesar Hernandez, 2B PHI— Not many Philadelphia Phillies turn out to be fantasy relevant these days, but in deeper formats, Hernandez could be the guy for you. In 127 games last year, the switch-hitting second baseman hit .272 with 57 runs scored, 25 extra-base hits and 19 stolen bases. He is a streaky hitter and it’s shown in 2015 and now in 2016. Last year, he had three months where he hit above .270, but he also had three months where he hit below .250. It’s still early in the month, but this is shaping up to be a solid month for the quick second baseman. Hernandez has four multi-hit efforts in six contests and even though he’s only swiped one base, that number will rise with time. His BABIP sits at a whopping .500 now, so while he is going to regress, a career .349 mark should keep a fair amount of luck on his side. Sure, he isn’t going to help you at all with homers and ribbies, but there are other guys to fill that need. If Odubel Herrera and Maikel Franco could get hot behind him, Hernandez could go on a nice binge of racking up hits and tallying up the runs. He’s really only an option in NL-only formats, but those in really deep mixed leagues could make a case for Hernandez if you’re desperate for steals.

Nick Tropeano, SP LAA— Superb. That’s how I would describe Tropeano’s season debut against the Oakland Athletics. He fired five shutout innings, striking out six in the process. The 25-year-old carries some fantasy value with him and he is going to make at least a few more starts while Andrew Heaney deals with a forearm issue. If he pitches well, not only could he stick in the Angels’ rotation, but he could find a niche on your fantasy staff. He’s only made 12 starts at the big league level, but he oozes potential. In seven starts (eight appearances) with the Angels last year, he went 3-2 with a 3.82 ERA. Nothing spectacular, I get that, but he managed to fire strikes 63.9 percent of the time, and post a 3.8 K/BB ratio. He struck out 38 batters in 37.2 innings and he is a guy who can post a K/9 around or above 9.0 in 2016. Is that unusual for the right-hander? Nope, not in the slightest. In 39 appearances (36 starts) at Triple-A, Tropeano punched out 216 in 212.2 innings. His 3.1 K/BB rate at the Triple-A level shows that last year’s number was no outlier for Tropeano. Seasonal owners pay attention, because his next start comes against Minnesota, the team who leads the MLB in strikeouts. He is a worthy addition while he is in the Los Angeles rotation.

Nomar Mazara, OF TEX— The top prospect in the organization received the promotion when regular outfielder Shin-Soo Choo went down with a calf strain. Texas had no qualms with sticking the young gun right in the two hole, slotted directly in front of Prince Fiedler. In two games, Mazara is 5-for-8 with a home run, two RBI and two runs scored. The kid has potential to be an annual 25-homer guy, but we all have to keep in mind that he is just 21 years old and is the youngest kid in the majors. Pitching is going to adjust to him at some point, but Texas believes he is able to handle it. I mean, you don’t receive a 55 hit grade and a 60 power grade if you’re doing something terribly wrong, right? He’s played in only 23 games at the Triple-A level, but he mashed there, hitting .376 while striking out just 11 times in 93 at-bats. Between Double and Triple-A, Mazara homered once every 32.6 at-bats, but as he continues to develop, that number will drop down. When Choo comes back, playing time could be a bit shaky to come by, which is why he needs to play well during his time in the majors. If he is available in your league, go ahead and pick him up, but if he continues to stay hot, this is a guy who can really help your club. Even if he does struggle, trust me, this isn’t the last we’ll be hearing of Nomar Mazara. This guy is legit.

Mallex Smith, OF ATL— It wasn’t the prettiest of debuts for Smith, literally, because he left the game with a laceration above of his left eye. However, before exiting he was able to record his first, score his first run and get caught stealing for the first time in his major league career. Sure, he got popped trying to steal second, but the bigger picture here is that the team is going to let the speedster run immediately at this level. It’s also encouraging that Atlanta put the speedy outfielder at the top of the order in his debut. To reach his fantasy potential, that’s where he needs to be and the team envisions him as a top of the order guy for his career. In 394 career minor league games, Smith swiped a whopping 227 bases. The guy can run, but do we have another Billy Hamilton on our hands? Hamilton actually hit more homers in the minors than Smith, but Smith’s Triple-A slash line of .287/.344/.382 was far better than Hamilton’s, which was .256/.308/.343. If he gets off to any sort of slow start, everyone is going to throw him in a similar category with Billy Hamilton, but I urge you to believe otherwise. Smith’s hit grade was a 50, while Hamilton’s was a 40. The other big difference between the two is that Smith knows his game and plays to it, while Hamilton, to be quite honest, kind of just does whatever he wants up there. If you want some stolen bases, then go ahead with Smith, because he can surely do that.

John Jaso, 1B PIT— A first baseman isn’t a typical leadoff hitter, but Jaso is succeeding in that role in Pittsburgh. Through the first seven games of the season, Jaso is slashing .321/.375/.500 and as long as he is getting on base for Andrew McCutchen and Starling Marte, he shouldn’t be in any jeopardy of losing his job. Jaso is owned in under 20 percent of ESPN fantasy leagues, and one would begin to wonder why. Well, it’s actually not that much of a mystery. For his career, Jaso homers just once every 43.7 at-bats, he’s never driven in more than 50 runs in a season and he’s stolen just 15 bases in 557 career games. Through the first seven games, his BABIP sits at .360, well above his career .295 mark. At some point, Jaso will come back closer to his career numbers. However, in 2016, Jaso looks good to begin the year and hitting in front of Andrew McCutchen should help him set a career-high in runs. He isn’t going to help you in the power departments, but if you need an immediate boost in RBI and runs, Jaso can provide a quick boost to your lineup.
