Waiver Wire is our weekly 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. We’ll be here all season to let you know which players to watch, who to ignore, and most importantly, who to pick up. If you have any waiver wire questions, feel free to post them in our Fantasy Baseball Forum.

Add in all Leagues

Tom Wilhelmsen SEA | RP

Wilhelmsen will continue to be on this list until he is owned in more leagues. He has proven to be one of the most consistent closers in the league this year, and he continues to get the job done. He has only blown 1 save since taking over as the Mariners closer, and he has 8 saves in the last month. (about 65% owned)

Chris Johnson ARI | 3B

Johnson has been playing great since the break, and he has made a nice first impression with his new home in Arizona. I don’t think Johnson has a huge upside, but he has proven that he can bat for average in the past, and I think he could end the year as a top 12 third basemen. If you at all need help at third I think you need to give Johnson a serious look. (about 40% owned)

Josh Rutledge COL | SS

I wasn’t totally buying it when Rutledge was called up and instantly starting to produce. However, with about 100 major league at bats he is still racking up the hits. Not only is he batting well over .330, but he has 3 bags and 6 home runs as well. The shortstop position this year has proven to be a tough spot to fill, so if Rutledge is still available I think it’s time to pick this kid up. Also, don’t necessarily worry about the return of Tulowitzki, the Rockies are already talking about giving him some playing time at second base. (about 50% owned)

Justin Morneau MIN | 1B

I was shocked and disappointed to see that Morneau was only owned in about half of all fantasy leagues. I know he plays a position that is easy to fill, but since the All-Star break he is batting over .340 with solid power numbers. It seems a lot of fantasy owners have their sights set on younger more exciting players, but don’t forget about the older more proven former MVPs of the league. Morneau is still young enough to have a huge upside, and since he has put up these type of numbers before I think there is a chance he can maintain this pace. (about 50% owned)

Add in Deeper Leagues

Michael McKenry PIT | C

This young catcher for the Pirates has really started to get things going as off late, and after a slow start to the season he has his average all the way up to .284. McKenry has proven he can bat for power, and since the break he has 4 HRs with a .368 average. He didn’t have a ton of success in the minors so I am not totally buying these numbers, but he has certainly got my attention with what he has been able to do in the last month. (about 15% owned)

Ryan Ludwick CIN | OF

You have to go all the way back to ’08 for when Ludwick last had a huge fantasy impact, but he is starting to make some noise in 2012. He isn’t batting for the best average on the season, but he has 19 HRs so far this year, including 7 since the all-star break. There is a good chance he will come back down to earth, but he is still young enough to put up numbers, and he has proven this year he can still bat for power. (about 40% owned)

Ben Revere MIN | OF

If you are looking for help with HRs then Revere is not your guy, but if you need help with average and speed then look no further. Revere is putting together a great year, and anytime you can have a guy that has a lot of speed and can bat over .300 then they are worth a roster spot in most leagues. Revere has 27 bags on the year so far, and he currently has a .325 batting average. He is only 24 years old so there is a chance for some power down the road, but for now he is just a speed specialist. (about 40% owned)

Paul Maholm ATL | SP

Maholm has never had an amazing fantasy season, but he is putting together a solid year so far in 2012. He as especially been good since the all-star break, posting a sub 2 ERA with almost a K per inning. Maholm is now on the Braves so he should get decent run support, and while I don’t think he can keep up his current pace I think he could certainly make a fantasy impact during the second half of the season. (about 50% owned)

Mike Minor ATL | SP

Minor was one of our favorite deep sleepers coming into the year, but so far he has been extremely inconsistent. However, he has really started to get things going as of late. In the last month he has just under a strikeout per inning, and a sub 2 ERA. This youngster for the Braves does still have a big upside, and I think he is worth a look in deeper leagues. (about 45% owned)

Add to Watch List

Daniel Straily OAK | SP

Straily is one of the best young arms in the game, and has a huge upside. He dominated in the minors before getting called up this year, posting a solid ERA and striking out well over a batter per inning. Straily is going to be up and down with his production this year, but he should have a lot of solid starts. I think he is worth an add in all keeper/dynasty leagues, and he is even worth a look in deeper redraft leagues. (about 10% owned)
