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

Jesús Guzmán SD | 1B

Guzman offers something that not a lot of first baseman can offer, and thats speed. In 126 AB’s so far this season he has 7 SB’s, to go along with a .349 average and 5 HR’s. The Padres had a big hole to fill with Adrian Gonzalez going to Boston, and it looks like they may have found their guy. (about 30% owned)

Mike Carp SEA | 1B/OF

After dominating in the minors Carp was called up, and his bat has not cooled off. He is batting well over .300 since being called up, with decent power numbers. He is a nice gamble if you need help at 1B or OF. (about 10% owned)

Javy Guerra LAD | RP

It’s a shock that Guerra is only owned in about half of then fantasy leagues right now. He has done nothing but impress, and we feel he has a strong hold on the closer role in LA. We see no reason why he shouldn’t be owned in all leagues at this point. (about 50% owned)

Iván Nova NYY | SP

Nova isn’t going to blow you away with his ERA or K’s, but he is finding ways to get wins. He has won 7 of his last 8 starts, and he hasn’t given up more then 4 runs in any of those outings. The Yankees are going to give him a lot of run support, so if you need help with wins then you might want to give Nova a look. (about 30% owned)

Justin Morneau MIN | 1B

After another long stint on the DL, Morneau was finally activated. He was doing pretty well in the minors and will hopefully go back to his power hitting ways. He should be picked back up in all leagues. (about 70% owned)

Stephen Strasburg WAS | SP

Believe it or not it looks like Strasburg will make it back to the majors in 2011. He already has his fastball back up into the upper 90’s, and so far in the minors he has been pitching great. The Nationals are going to be cautious with his pitch count, but we think he is a great gamble at this point if you need a starting pitcher. (about 40% owned)

Hideki Matsui OAK | OF

Matsui is the proud owner of the hottest bat in baseball, and if he is available you should consider riding out this hot streak. In the last month he is batting .432 with 5 HR’s and 24 RBI’s. He will more than likely come crashing back down to earth at some point, but if he stays healthy he could give your team good value down the stretch. (about 40% owned)

Nathan Eovaldi LAD | SP

In 2 starts so far in the bigs, Eovaldi has been very impressive. A spot in the rotation opened up when De La Rosa went out with his elbow injury, and Eovaldi has filled in nicely to this point. He has a K per inning, and he has only given up 2 earned runs in 11 innings pitched. Eovaldi is a great young pitcher that is worth picking up in some leagues, but at the very least keep a close eye on him. (about 5% owned)

Edwin Encarnación TOR | 1B/3B

Encarnacion has been around for a while and he has never really been fantasy relevant. But he started to show some signs of life last year, and he has carried that into the second half of this season. In his last 90 AB’s he is batting .360 with decent speed and power. Another plus for Encarnacion is his duel position eligibility. (about 15% owned)

Jesus Montero NYY | C

Montero had a lot of hype around in before the season, but he has yet to get called up to the bigs. He has been doing ok in the minors, but nothing amazing so thats part of the reason he is still not in the bigs. With reports that Posada will not see as much action at DH, it sounds like he might be getting the call sooner rather then later. We aren’t expecting huge things from Montero right away, but he should have plenty of RBI opportunities on that high powered Yankee offense. (about 10% owned)
