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 19 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

Matt Shoemaker LAA | SP

After the year that Shoemaker had last season I was surprised to see how many owners gave up on him after his slow start. It seems like he has figured things out and he has been pitching great since mid June. Shoemaker has lowered his ERA to 4.00 and his K rates as of late have been amazing. (about 55% owned)

Joe Ross WAS | SP

I think this kid is the real deal. His minor league stats were solid and he has carried his success right into the bigs. So far this year he has over a K per inning and an ERA of 3.00. This 22 year old is certainly a staring pitcher that could help fantasy squads down the stretch. (about 30% owned)

Randal Grichuk STL | OF

This youngster is quietly having an amazing year. He is only owned in about half of all leagues and he has a legit chance to be the NL rookie of the year. In just over 250 at bats he has 40 extra base hits and after looking at his minor league stats I don’t think this is a fluke. (about 50% owned)

Jimmy Nelson MIL | SP

Young pitchers often have major ups and downs as hitters adjust and learn how to handle them. I believe this is the case this year with Nelson. He got off to a solid start and then got rocked for the month of June. Just like the hitters though, pitchers make adjustments as well to make sure they aren’t tipping pitches or being too predictable with what pitches they throw. Whatever adjustments Nelson made are working, he had an amazing July and looks to be back on track. (about 35% owned)

Luis Severino NYY | RP/SP

Severino has been in the Yankees farm system since he was 18 and after three years of tearing it up in the minors he is finally getting his shot. He had a 2.30 lifetime ERA in the minors and over a K per inning. I think this kid has a bright future and a great gamble if you need help at starting pitcher. (about 45% owned)

Adam Eaton CWS | OF

If you have been reading this article throughout the year then you know that I am a big Eaton fan. He has hit safely in 18 of his last 20 games and during that stretch he has raised his average by 20 points. The guy can do it all and I am excited about his potential during the second half. (about 65% owned)

Mark Buehrle TOR | SP

After a terrible first two months of the season it looked like Buehrle’s days as a fantasy relevant pitcher were over. The old man has gotten things going as of late though and I like him as an add. He has had a quality start in ten of his last 12 starts and it’s impossible to ignore those stats. (about 65% owned)

Add in deeper leagues

Alex Wilson DET | RP

With Joakim Soria now in Pittsburgh, this has opened the door for Wilson to pitch in the 9th for Detroit. Wilson is having a great year, but I am not sold on him as a closer. Even though he has a solid ERA, he is only averaging about .5 strikeouts per inning and that worries me. He should get a decent amount of save chances though, so this makes him an interesting add in some leagues. (about 30% owned)

Yangervis Solarte SD | 1B/2B/3B

Solarte is eligible to play three different infield positions and that’s only one of the reasons why I like this guy. This is his first full season in the bigs and he is taking full advantage, Solarte has 32 extra base hits in just 331 at bats and his batting average is decent. The only downside with Solarte is that he doesn’t offer much in terms of speed. (about 15% owned)

Asdrubal Cabrera TB | 2B/SS

The shortstop position has been a tough one this year and there are many teams looking for an upgrade at that position. Cabrera could be the answer for some teams, it looks like he is turning things around and I like him moving forward. Since mid June he has raised his average 50 points and I think he could end the year as a top ten shortstop. (about 60% owned)

Brett Anderson LAD | SP

We know what Anderson is capable of when healthy and I think he deserves to be owned in more leagues. He has pitched great for three straight months and even though he doesn’t have top tier potential, he does makes a solid 4th or 5th starter. I expect him to be close to a K per inning, with an ERA right around 3.00 for the rest of the way. (about 25% owned)

R.A. Dickey TOR | SP

The knuckleball is a tricky pitch and it’s hard to be a consistent pitcher when that is your main weapon. It looked like Dickey had lost his touch with the knuckleball, but as of late he has found his touch. As of late he has been the Dickey of old and it’s possible he could become fantasy relevant again. Even though I don’t think you should run to your computer to pick this guy up, it looks like this forty year old pitcher might still have something left in the tank. (about 40% owned)

Jonathan Schoop BAL | 2B/3B

This youngster has a lot going for him in the fantasy world. He has dual position eligibility at tough positions to fill, he has great power, a solid average and he is only 23 years old. I think his batting average is a bit fluky, but I think he could bat around .280 with solid power for the rest of the 2015 fantasy season. (about 10% owned)
