Our fantasy baseball waiver wire column takes a look at players available in many leagues that could have an immediate impact on your fantasy roster, or simply just players to keep on your radar. Let’s take a look some of the top waiver wire pickups heading into Week 3 of the MLB season. If you have any questions on who to pick up or who to drop, feel free to post them in our Fantasy Baseball Forum.

Add in all leagues

Todd Frazier CIN | 3B

I was surprised to see how many leagues that Frazier was still available in. While his average wasn’t the best last year, he did have 51 extra base hits and 19 home runs. He has huge power potential and he has hit for average in the past. He has a big upside and at 28 years old, there is a good chance that we haven’t seen his best year. (about 60% owned)

Melky Cabrera TOR | OF

Let’s not forget that Melky was batting just under .350 in 2012 before getting busted for juicing. He went un-drafted in many leagues after his subpar 2013 campaign, but after his hot start this year you need to think about picking him up. He is a legitimate candidate to win the American League batting title and I like his potential moving forward. (about 55% owned)

José Valverde NYM | RP

With Parnell done for the year, this opens the door for Valverde to take over the 9th inning duties. The old man has a little left in the tank and he has a great opportunity to be relevant again in the fantasy world. (about 60% owned)

Anthony Rendón WAS | 2B/3B

Rendon has been on fire in 2014 and he is quickly getting picked up in a lot of leagues. If for some reason he is still available in your league, then you need to run and snag him. He is a young infielder with a huge upside and he has dual position eligibility. (about 70% owned)

Add in deeper leagues

Dee Gordon LAD | 2B/SS

Gordon was on a lot of people’s sleeper lists last year, but he disappointed his owners. At 25 years old though it’s too early to give up on this talented young infielder and he is off to a great start so far this year. If you need any help with your middle infield then he is a great guy to grab. (about 60% owned)

Ryan Cook OAK | RP

Jim Johnson didn’t last too long as the A’s closer and all signs are pointing to Cook as the next guy in line. They might deploy somewhat of a committee at first, but my money would be on Cook as the guy to own out of the group. He has had decent success over the last couple of years and I think he could be an effective closer. (about 20% owned)

Charlie Blackmon COL | OF

Blackmon was on our deep sleeper list and even though he started the year as the Rockies 4th outfielder, he is still a guy that’s worth picking up. He is too good for the Rockies to leave on their bench and I fully expect him to have solid at bat totals this year. He was great in limited at bats last year and he could flirt with being a top 50 fantasy outfielder in 2014. (about 50% owned)

Trevor Plouffe MIN | 3B

Plouffe has yet to put it all together at the big league level, but I think this could be the year. He has the potential to bat for power and I think he could have a decent average as well. There is a chance that Plouffe could end the year as a top 15 fantasy third baseman and because of that he should be owned in more leagues. (about 20% owned)

Nathan Eovaldi MIA | SP

The young right hander for the Marlines is a guy that I have always been a fan of. While I like his overall upside you shouldn’t expect him to have huge strikeout totals. He isn’t going to be a top tier pitcher, but I think he could crack the top 50 among fantasy starting pitchers in 2014. (about 25% owned)

Shawn Kelley NYY | RP

Kelley is worth a look as a short term solution since Robertson is on the DL. He isn’t off to the best start this year, but he should be a decent source of saves over the next couple of weeks. (about 30% owned)

Chris Colabello MIN | 1B/OF

Colabello has been a life time minor leaguer, but he is finally getting his shot in the big leagues. He is taking full advantage of the opportunity and has played great so far in 2014. He already has 11 RBIs on the young season and he is worth a look in deeper leagues if you need help at first base or outfield. (about 35% owned)

Marcus Semien CWS | 2B/3B

The young starting second baseman for the White Sox is an interesting fantasy option. I don’t think he will bat for the best average, but he should offer a decent mix of speed and power. Another thing I like is his dual position eligibility with second and third base eligibility. (about 5% owned)

Keep an eye on

Adam Ottavino COL | RP

Even though the Rockies bullpen is a bit crowded I still like Ottavino as a guy to consider picking up. He has been amazing so far this year and if Brothers or Hawkins slip up at all, I wouldn’t be surprised if we see him pitching in the 9th inning for the Rockies. It’s a bit of a long shot, but even if he doesn’t take over the closer role he is still a solid relief pitcher with big strikeout potential. (about 5% owned)

Jenrry Mejía NYM | SP

The thing I like most about Mejia is his strikeout potential. He is a young unproven pitcher, so he is going to have some bad games, but I still think he is worth keeping a very close eye on. If he can control his walks then I think he could have solid fantasy value. (about 15% owned)
