Our Fantasy Baseball Waiver Wire Pickups article 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 at some players that might be worth scooping off the waiver wire heading into Week 4 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

Shelby Miller STL | SP

Miller has everything you look for when it comes to trying to find the next great fantasy pitcher. He is a young talented pitcher with huge K potential and he is off to a great start so far this year. The 22 year old had 160 Ks in 136 innings in the minors in 2012 and I am expecting big things from him this year. (about 65% owned)

Starling Marte PIT | OF

It seemed like Marte got a decent amount of preseason hype, which makes it even more surprising that he isn’t owned in more leagues after his hot start to this season. Last year he had 14 extra base hits in only 167 at bats and he already has 5 extra base hits in 2013. Marte is an extremely talented young player and he is well worth an add in all leagues.

Daniel Murphy NYM | 1B/2B

Murphy was one of my favorite sleepers coming into the season and he is off to a great start. I thought he would improve upon his home run numbers since he had so many extra base hits last year. In 2012 he only hit 6 HRs and he already has 2 HRs and 8 extra base hits on this young season. He also has dual position eligibility and I think this all adds up to him being a must add. (about 70% owned)

Everth Cabrera SD | 2B/SS

Cabrera was one of my favorite shortstop sleeper coming into the year and he is starting to show why. He isn’t going to bat for the best average or for much pop, but he has the chance to league the league in steals. When you combine that with the fact he can play second base or shortstop for your fantasy team, you have to love this guys upside. (about 70% owned)

Add in Deeper Leagues

Tony Cingrani CIN | SP

Cingrani is one of the best young pitching prospects in the game and he just got called up to the bigs. He has been very impressive in the minors and he has the stuff to be a great fantasy pitcher. His spot in the starting rotation isn’t guaranteed going forward, but if he pitches well he could find himself in the majors for good. (about 30% owned)

Chris Carter HOU | 1B/OF

I am not expecting a great average out of Carter, but he could be a solid source of cheap power for your fantasy team. He displayed solid power in limited at bats last year and he already 4 HRs in 2013. Carter had solid numbers during his time in the minors and I really like his overall upside. (about 40% owned)

Matt Adams STL | 1B

The Cardinals are going to have to find a way to get their young power hitter some more at bats. He has only had 18 at bats so far this year, but he has 11 hits and 3 HRs. Some might call it a fluke but this didn’t come out of nowhere, he was solid during his time in the minors and this kid does have obvious talent. In 276 at bats in 2012 in the minors he had 18 HRs and 50 RBIs. (about 15% owned)

Yonder Alonso SD | 1B

Alonso was a guy that I really liked coming into the season and he is off to a great start. He didn’t hit for a ton of power last year, but I loved the fact that he had 39 doubles. A lot of times with younger players those doubles will turn into HRs and I think that’s going to happen with Alonso. He has 2 HRs already and I think he will be up over 20 this year before it’s all said and done. (about 15% owned)

Keep an eye on

Edward Mujica STL | RP

The Cardinals closer situation is currently a mess and it looks like Mujica could be the next guy in line for the save opportunities. He has been solid thus far for the Cards pen and he is certainly worth keeping a close eye on. Jason Motte will be back in the fairly near future to reclaim his closing role, but Mujica could be a decent source of saves until that happens. (about 40% owned)
