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 7 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

Jung Ho Kang PIT | 3B/SS

Kang was one of our favorite sleeper infielders coming into the season, but things weren’t looking so great early. Lately though he has been turning things around and it’s time to start paying this guy some attention. He had amazing stats in the Korean leagues and he is far from a rookie. (about 25% owned)

Yasmani Grandal LAD | C/1B

The 27 year old catcher appears to be 100% healthy and his stats are reflecting that. He has nine extra base hits in 81 at bats so far this year and he is batting over .300. I have always been a Grandal believer and it looks like this might be the year when he puts it all together. (about 60% owned)

A.J. Ramos MIA | RP

The Miami closer situation is currently a mess, but Ramos makes the most sense as an add right now. He has pitched great so far this year with over a K per inning and an ERA just above 1.00. The only thing that scares me is Miami’s reluctancy to flat out name him the closer. While I do like Ramos there has been talk of a committee or even bringing in another arm that could compete for save opportunities. (about 40% owned)

Jimmy Paredes BAL | 3B

Paredes was on this list two weeks ago as a must add in deeper leagues and his bat is still on fire. I think this kid could be the real deal and at this point though I think he needs to be added in all leagues. In 84 at bats he already has 13 extra base hits and he is hitting the ball hard all over the ballpark. (about 50% owned)

Add in deeper leagues

Noah Syndergaard NYM | SP

There is a lot of hype around this youngster and for good reason. He is one of the top pitching prospects in the game right now and he has been pitching great in the minors. His first start in the bigs wasn’t terrible and if he pitches well then there is a good chance that he holds onto one of the starting rotation spots. (about 60% owned)

Shin-soo Choo TEX | OF

It looked like the days of Choo being fantasy relevant were over, but maybe he still has some gas in the tank. He is coming off a terrible 2014 and the start of his 2015 season was extremely slow. He has really picked things up lately however and I like him as an add right now in case he is able to keep this up. (about 60% owned)

Chris Young KC | SP

The 6’10” starting pitcher is off to an amazing start this year and the Royals would be stupid to take him out of the starting rotation. So far in 23 innings of work he has a sub 1.00 ERA with almost a K per inning. I am not totally buying his start, but he has had solid seasons in the past. At the very least I think he is worth an add so you can ride out this hot streak. (about 35% owned)

Tim Lincecum SF | SP

Lincecum hasn’t been fantasy relevant since 2011 and it’s hard to trust his start so far this year, but I don’t think we should ignore it either. Lincecum was one of the best pitchers in the league for many years and at only 31 years old there is a chance he could return to his old form. I think he is well worth the gamble if you are looking for some starting pitching. (about 50% owned)

Carlos Correa HOU | SS

The Astros have called up their young shortstop prospect and I like his chances of making an instant impact. The 2012 first overall pick from Puerto Rico has been nuts so far this year in the minors, batting .385 with 24 extra base hits in only 117 at bats. He also has thrown in 15 stolen bases so far this year as well. Correa has the potential to do it all and I love his upside moving forward. (about 20% owned)

Jonathon Niese NYM | SP

Niese isn’t exactly the most exciting arm in the game, but he is still a fantasy relevant pitcher with three straight years of decent K counts and a sub 4.00 ERA. At 28 years old there is still a decent chance that we haven’t seen the best out of Niese and he has been amazing so far in 2015. I think he makes sense as a 5th or 6th starter for any fantasy squad looking for pitching help. (about 30% owned)

Keep an eye on

Rubby De La Rosa ARI | SP

I was a huge Rubby fan when he first came on the scene back in 2011, but he fell off the fantasy map after blowing out his elbow. It looks like he might finally be back to being close to 100% and I think it’s time to keep a close eye on him. He is only 26 years old and I think he has breakout potential this year.
