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.

Addison Reed CWS | RP

We have been high on Reed all year, and now he is finally going to get his shot to be the closer for the White Sox. If you look at his overall numbers they don’t look that great since his ERA is over 4, but all of his earned runs came from one bad outing against the Royals. He is a high strikeout pitcher with a ton of upside, and I think he needs to be owned in all leagues at this point. (about 50% owned)

James McDonald PIT | SP

McDonald has really started to impress lately, with 7 or more strikeouts in each of his last 6 starts. At this point I think he is worth a roster spot in all leagues to see if he can keep this up. I think he will come back down to earth to some point, but he has just been too good to leave him on the waiver wire. (about 70% owned)

Ernesto Frieri LAA | RP

It is an absolute shock to me that Frieri isn’t owned in more leagues. The guy is the new closer for the Angels, and he is averaging almost 2 Ks per inning. I think he has top 3 closer potential, and you need to pick him up immediately if he is still available. (about 30% owned)

Jonathan Lucroy MIL | C

This just in, Lucroy is having an amazing year but he is getting no respect in the fantasy baseball world. Lucroy is a 26 year old catcher who had upside coming into the season, and he has been on fire. He already has 18 extra base hits, and almost 30 RBIs. Lucroy is currently playing as a top 3 catcher and he is still available in a ton of leagues. It’s time to start thinking that this guy could be for real, and pick him up to see if he can continue on this hot streak. (about 55% owned)

Bud Norris HOU | SP

The thing I like most about Bud Norris so far this year is his consistency. 7 of his 9 outings have been quality starts and he is also averaging over a K per inning thus far. I am not expecting huge things from Norris this year, but when you combine his consistency and strikeouts he is a solid fantasy pitcher. (about 65% owned)

Jed Lowrie HOU | 3B/SS

Lowrie continues to be a solid fantasy player, but he is still available in a lot of leagues. For a guy that has dual infield position eligibility, I would have expected him to be owned in more leagues. He is on pace for over 20 HRs and about 80 RBIs, and he is the perfect utility guy for any fantasy team. (about 50% owned)

Andy Pettitte NYY | SP

Pettitte has gotten off to a good start since coming back for the Yankees. He has created a bit of a stir in the fantasy world, and I think he could have some value for the rest of the season. I don’t think he will keep up this pace, but he could easily put up similar numbers from his 2010 season. (about 40% owned)

Mitch Moreland TEX | 1B/OF

Moreland had a lot of hype around him when he came out of the minors, but he has yet to live up to it. He showed flashes last year, but his average was never anything to write home about. This year however he is still batting for solid power, and he has brought up his average by almost 20 points. He is going to get some nights off against some lefty pitchers, but I still think Moreland is worth a look in some leagues. (about 35% owned)

Trevor Bauer ARI | SP

If you have been following the hot prospects that might have a fantasy impact this year, than you have heard of Bauer. The young talented pitcher has been playing great in the minors, and a call up to the bigs seems imminent. He will more than likely be somewhat inconsistent, but Bauer should get the full attention of the fantasy world very soon. (about 10% owned)

Anthony Rizzo CHC | 1B

It’s only a matter of time before Rizzo gets called up. He is doing great in the minors this year with 16 HRs already and he is batting over .350. Rizzo is one of the biggest prospects in the game, and could have an instant fantasy impact. (about 10% owned)

Felix Doubront BOS | SP/RP

The young starting pitcher for the Red Sox is starting to make some noise. He has won 3 of his last 4 starts, and he is averaging over a K per inning so far this year. His walks and WHIP are a bit of a concern, but he certainly has a big upside. Since his whip is so high he hasn’t gone past the 6th inning in any of his starts this year, but if he can get his walks under control he could be a big time fantasy pitcher. (about 15% owned)
