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 5 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.

Must add in all leagues

Mike Moustakas KC | 3B

This might be the year, the year that Moustakas finally lives up to the hype that was around him when he came into the bigs back in 2011. He has had some solid stats, but he has yet to have that breakout campaign. 2015 has treated him well thus far and I think he is well worth an add to see if he can keep up this pace. (about 60% owned)

Josh Reddick OAK | OF

It was only two years ago that Reddick hit 32 home runs and had 11 stolen bases, it seems like the fantasy world has forgotten about this guys potential. He is only 28 years old and it looks like he is back to his 2013 form. Reddick started the year on the disabled list and I think that is the main reason why he wasn’t draft in more leagues. (about 25% owned)

Brett Cecil TOR | RP

With Cecil it’s simple, he is now the closer for the Blue Jays. He hasn’t been great this year, but if you are looking for some cheap saves then he is your man. Cecil has had two straight solid years throwing from the pen and I fully expect him to get his ERA down toward his normal numbers. (about 55% owned)

Adeiny Hechavarria MIA | SS

The stats for Hechavarria have gone up each year that he has been in the bigs and I think he could be on the verge of a breakout season. He already has 16 runs and 16 RBIs on the young season and he is batting well over .300. I would be surprised if he is able to maintain his batting average, but I think he has a legitimate chance to be a top five fantasy shortstop this year. (about 70% owned)

Danny Santana MIN | SS/OF

Santana was one of my favorite sleepers coming into the year, but for the most part he has been a huge disappointment. I think he has turned the corner though and I am still expecting big things from him in 2015. He has dual position eligibility and I don’t think his numbers last year were a fluke. If he is available in your league and you are looking for a youngster to take a gamble on, then look not further. (about 50% owned)

Add in deeper leagues

Jimmy Paredes BAL | 3B

The Orioles might have a star on their hands with Paredes. He joined the Yankees back in 2007 when he was 18 and he has been up and down from the minors ever sense. At this point though I think he is up for good and he has the potential to do it all. Pick him up if you need help a third and see what happens. (about 25% owned)

Alex Guerrero LAD | OF

Guerrero is too good of a player to be sitting on the bench and the Dodgers are going to have to find a way to get this guy some more at bats. He had great stats in the Cuban leagues, he killed it in the minors last year and so far in limited at bats in 2015 he has been nothing short of amazing. If you pick up Guerrero just be ready for some nights where he isn’t in the lineup, but I would be shocked if the Dodgers don’t do something to get him more regular playing time. (about 45% owned)

Josh Hamilton TEX | OF

I have never been a huge fan of Josh Hamilton. I feel he is overrated and almost always injured. That being said the guy is better than being owned in less than half of fantasy leagues. If he is able to come back in 2-4 weeks and he is by some chance able to stay healthy for most of the season, then you will be happy that he is on your team. If you have an empty DL spot then scope him up and wait him out. (about 30% owned)

Zack Cozart CIN | SS

Cozart has been a full time big leaguer since 2012 and he even though he has had some success, he hasn’t had a breakout year just yet. When you look at his start to the season you can’t help but think that maybe this is the year. He has already matched him home run totals from 2014 and he is batting 40 points over his career average. (about 45% owned)

Juan Lagares NYM | OF

Lagares isn’t going to give you much power, but the young Dominican has a nice overall upside. He is currently hitting second for the surprising Mets and he is taking full advantage of the regular playing time. Lagares is only 26 years old and I think he will build on his numbers from last year and he could easily be a top 40 fantasy outfielder this year. (about 15% owned)

Ike Davis OAK | 1B

It’s clear that fantasy owners aren’t believing the .328 average for Ike Davis, because he is still available in almost all fantasy leagues. At this point though I think people need to give Davis a longer look. He is only 28 years old and I think a breakout year is still highly possible for him. (about 5% owned)

A.J. Pierzynski ATL | C

The old man can still find a way to be relevant in the fantasy world. Obviously A.J. is over performing right now with his .439 average, but I don’t mind the idea of riding out this hot streak. If you are one of the owners that is waiting for Yan Gomes or Matt Wieters to return, then Pierzynski could be the perfect fill in. (about 40% owned)
