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 9 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

Shawn Tolleson TEX | RP

When Tolleson first started saving games for the Rangers not many people were running to their computers to pick him up. He had an ERA over 3.00 and overall he just didn’t seem like that exciting of a pickup. Since taking over the job however, he is a perfect five for five in save opportunities and he has six Ks during those five innings. He seems to like the added pressure and I don’t think Neftali Feliz will be getting his job back any time soon. (about 55% owned)

Jimmy Paredes BAL | 2B/3B

I am not totally buying Paredes this year, but after gaining second base eligibility last week I think he should be owned in all leagues. Even though he will come back down to earth at some point I think he has too much going for him to not pick him up. He has also recently added a couple more stolen bases, so just chalk that up as one more reason to like this kid. (about 70% owned)

Add in deeper leagues

Lance McCullers HOU | SP

I was shocked to see how many leagues McCullers was still available in. He has a good amount of hype around him, he pitched well in the minors this year and he has been solid since getting called up. Maybe people are still stuck in 2014 thinking that the Astros won’t be able to get him any run support, but they have surprising already won 30 games this year. (about 25% owned)

Mike Bolsinger LAD | SP

Bolsinger has been nothing short of amazing so far in 2015 and at this point it’s the classic question, “is this guy for real?”. Looking at his minor league stats he had some success, but nothing all that amazing until this year. It’s certainly possible that he has just figured things out, but more than likely he will come crashing back down to earth. Even with all that being said he is still worth a gamble as a young arm with an upside. (about 55% owned)

Carlos Correa HOU | SS

I don’t see how Houston can wait much longer to call up their stud young shortstop of the future. Correra has the potential to do it all and he should have an instant fantasy impact once he is called up to the big leagues. Considering Jose Altuve is only 25 years old, it’s scary to think how good the Astros middle infield could be for the forceable future. (about 30% owned)

Rubby De La Rosa ARI | SP

At this point it looks like Rubby might finally have all of the injury stuff behind him and we can now see what this guy can do. He is only 26 years old and I think the best is yet to come. The thing I like most about De La Rosa is his K potential. If he can stay healthy I think he will flirt with 200 Ks this year. (about 30% owned)

Carson Smith SEA | RP

Fernando Rodney has been terrible this year and I can’t imagine that he has too many more chances to pitch for the Mariners in the 9th. Carson Smith should be next in line if there is a change and he could instantly be a top 15 fantasy closer if given the opportunity. If you have an empty roster spot then I like the idea of grabbing Smith as a speculative add. (about 30% owned)

Adam Eaton CWS | OF

Considering what Eaton accomplished in the minors a few years back, I feel like he hasn’t had enough hype around him in the fantasy world. At only 26 I think there is still a great chance of him breaking out and showing us what he is capable of. He has a ways to go when it comes to his power numbers, but I think he has the potential to win some batting titles down the road. (about 30% owned)

Keep an eye on

Eduardo RodrĂ­guez BOS | SP

RodrĂ­guez has received a good amount of hype this week after getting called up and after looking at his minor league stats I can understand why. He has shown great control with a 44/7 K to walk ratio and a sub 3 ERA. All that being said I am not expecting him to have that much instant success, but he is still worth a look in deeper leagues if you need pitching help. (about 10% owned)

Chris Colabello TOR | 1B/OF

I have never fully trusted guys that don’t breakout until later in their careers, but Colabello is someone that everyone should keep a close eye on. He has been up and down from the minors for the last ten years and it looks like he might be finally getting a chance to be an every day player. He has had success in the minors so I don’t think his numbers are necessarily fluky and there is a chance that he becomes fantasy relevant this year. (about 10% owned)
