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 11 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

Jon Singleton HOU | 1B

Singleton was recently called up from the minors and I think he can make an instant impact. He is one of the biggest prospects in the league and his minor league stats were solid. It’s hard to say for sure how good he could be, but if you are looking to take a gamble on a youngster with a big upside than he could be your guy. (about 55% owned)

Grégory Polanco PIT | OF

Polanco has been in my waiver wire write-ups for well over a month now and it looks like he is going to finally get called up. He has Mike Trout type fantasy potential and at this point he should be owned in all leagues. Pick him up before it’s too late. (about 45% owned)

Héctor Rondón CHC | RP

I was shocked to see how many leagues that Rondón is still available in. He has great stuff and I think he could be the Cubs closer for the rest of the year. So far this season he has an ERA around 2 and well over a K per inning. He has a huge upside and if you at all need help with saves, then you need to snag this young pitcher. (about 50% owned)

Cody Allen CLE | RP

I am not a huge overall fan of Allen, but it looks like he is the guy to own as the Indians closer. My main beef with him is that he walks too many people and that he is always pitching himself out of trouble. Eventually that will catch up with him unless he is able to get his walks under control. He is still a closer though with a sub 3 ERA, so he is worth owning in pretty much all leagues. (about 45% owned)

Adam Lind TOR | 1B

When it comes to hot streaks Adam Lind is the king, too bad he rarely puts it all together for an entire season. With that being said though he is still worth owning at this point, since he is in the middle of one of his hot streaks. Who knows how long it will last, but you might as well enjoy the ride. (about 45% owned)

Khris Davis MIL | OF

We were a big fan of Davis heading into the year, but he let his owners down in the first couple of months and he was dropped in many leagues. He has started to get things going as of late though and I think it’s time to pick this kid back up. He has a huge overall upside and I think he could have a monster second half. (about 65% owned)

Add in deeper leagues

Corey Dickerson COL | OF

The Rockies have a crowded outfield and it’s been hard for Dickerson to get consistent playing time. This should change however with Carlos Gonzalez going on the DL. Dickerson has been amazing in limited at bats this year and even when Gonzalez comes back the Rockies are going to have to find a way to get him at bats. (about 15% owned)

Joba Chamberlain DET | RF

It’s been a long time since Chamberlain has been fantasy relevant and it took a move to the bullpen to make that happen. With Joe Nathan struggling as much as he is, it looks like Chamberlain might get a chance to take over as the Tigers closer. Nathan is going to be given every chance to keep his job, but if he keeps struggling the Tigers are going to have to make a move. (about 15% owned)

Josh Harrison PIT | 2B/3B/OF

Harrison has a proven track record in the minors and he has started to pick things up in the bigs. When you combine that with his position eligibility, then this makes him an interesting fantasy option. He is the perfect guy to pickup in daily setup leagues as a utility guy for your bench. (about 5% owned)

Lonnie Chisenhall CLE | 1B/OF

Chisenhall is starting to get the attention of the fantasy world, but I still think he needs to be owned in more leagues. He already has 18 extra base hits in just 144 at bats and he is currently batting over .360. When you combine that with dual position eligibility, it’s hard not to like this guy. (about 45% owned)

Eddie Butler COL | SP

Butler is one of the biggest pitching prospects in the game and he is about to get called up by the Rockies. His minor league stats are ok, but the thing that worries me about him is his lack of strikeouts. He is a big prospect though so he should have your attention; we will see how he does very soon at the big league level. (about 15% owned)

Oswaldo Arcia MIN | OF

Arcia didn’t get off to a good start this year, but he has turned things around and needs to be picked up in more leagues. He was a stud in the minors and I am expecting big things from him in the second half of the season. If you are looking for a young outfielder to take a gamble on, than look no further.
