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 18 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

Danny Farquhar SEA | RP

When you look at the year totals for Farquhar they aren’t that impressive, but he has been solid as of late. For now he has a pretty good hold on the 9th inning duties for the Mariners and as long as he doesn’t slip up, I see no reason for why he will lose his gig. He has nice strikeout potential and he fits the mold for what teams look for in a closer. (about 30% owned)

Andrelton Simmons ATL | SS

In my opinion Simmons is one of the most exciting young positional players in the league. He has solid power, some speed, and I think eventually he can bat for average. At only 23 years old he is already starting to bat for decent power and once he packs on a few more pounds he could be the best power hitting shortstop in the league. (about 55% owned)

Add in Deeper Leagues

Álex Rodríguez NYY | 3B

As is looks right now there is a chance that A-Rod will continue to play for the Yankees for the rest of the year. I wouldn’t expect huge numbers from him so don’t get too excited, however he is still capable of putting up solid stats. I think Rodríguez certainly feels like he has something to prove, so look for him to give it 100% for the rest of the year. (about 30% owned)

Danny Salazar CLE | SP

This young pitcher has amazing strikeout numbers and I am excited about his potential moving forward. So far he has only 1 start in the bigs, but it was an impressive outing with 7 Ks and only 1 earned run. Salazar is only 23 years old at this point and if you are looking for a young pitcher to take a gamble on then look no further. (about 10% owned)

Mike Moustakas KC | 3B

Moustakas already has 27 extra base hits on the year, but his .231 batting average is nothing to get excited about. He has however, recently started to get his average up and I like his potential for the second half of the season. He is only 24 years old and I think Mouse needs to get picked up in more leagues.

Justin Smoak SEA | 1B

Smoak is another young player that is starting to get things going. He only hit 8 home runs the first half of the season and he already has 3 since the break. Smoak has been in the league since 2010 and he has yet to put it all together, but I am not ready to write him off just yet. He is everything you look for when it comes to a young first basemen with upside, so it might be time to pick him up if you need help at that position. (about 15% owned)

Dan Haren WAS | SP

After a bad 2012 and a slow start to his 2013 season, Haren has fallen out of good graces for a lot of fantasy baseball owners. However, it might be time to start paying some attention to him again. He has had quality starts in 4 of his last 5 and he has at least 6 Ks in each of those outings. We all know what he is capable of when pitching well and at only 32 years old I am not completely writing off his chances of turning things around. (about 55% owned)

Iván Nova NYY | OF

Nova has been on a tear lately and I am surprised he isn’t getting picked up in more leagues. At this point I can’t imagine that the Yankees would take away his rotation spot and he is currently working on a streak of 8 straight quality starts. He should be able to get decent win totals and he currently has over a K per inning. (about 45% owned)

Keep an eye on

Heath Bell ARI | RP

Bell got off to a terrible start this year and he was dropped in a ton of leagues for his poor play. He has started to turn things around though and I think there is a chance he could end up taking over the closer role for the Diamondbacks. He is much more of a prototypical closer than Ziegler and Bell hasn’t given up an earned run since July 10th lowering his ERA to 3.55. (about 35% owned)

Bryan Shaw CLE | RP

This is a bit of a long shot, but I don’t mind the chances for Shaw to maybe take over as the closer for the Indians at some point this year. He has closer type stuff and with Chris Perez not exactly pitching lights out I think a switch is possible. Shaw’s numbers have never been that amazing but it’s hard to ignore the fact that he hasn’t given up any earned runs since Independence day. (about 5% owned)
