Fantasy sports leagues can be won or lost on the waiver wire. At this point in the season, snatching up a pitcher off the scrap heap is a nice way to boost one's chances of bringing home the championship.
Both Injuries and ineffectiveness can start to hamper your usual reliable pitching options in May, and to remedy that, here are some under-the-radar pitchers who can help your team greatly.
Addison Reed, Chicago White Sox
With Hector Santiago struggling, Chicago turned to former starter Chris Sale to finish games for them. Sale will undergo an MRI on an aching elbow, so Robin Ventura will now rely on Addison Reed to close out victories for the White Sox. Reed hasn't allowed a run in 13 innings of work this season, and if he can get a firm grasp on the closer spot, Reed will be a valuable pickup. Reed also has struck out 14 batters this season, so he should earn you points in that category as well.
David Robertson, New York Yankees
This one is a no-brainier, and if Mariano Rivera's replacement is still available in your league, you may want get David Robertson immediately. The past few save chances have been rough, though, seeing how Robertson has loaded the bases in his last two ninth-inning appearances. Barring an injury, Robertson will likely finish the season as the team's closer, and if he can replicate his eighth-inning success, he should thrive.
Jarrod Parker, Oakland Athletics
Jarrod Parker has future ace written all over him and if his first big league win was any indication, he may began to realize some of his potential this season. Parker led Oakland to a victory against the Red Sox while allowing allowing only one run. His second start against Toronto was solid as well, and Parker should keep a spot in the rotation. Oakland has been a surprise team this year and if they can give him decent run support, Parker will be a valuable fantasy option.
Eric Bedard, Pittsburgh Pirates
The veteran lefty has only won two games this season, but he has been pitching extremely well thus far. Bedard has 2.57 ERA while striking out 37 batters in 2012. He left his last start with back spasms, but if he is cleared, Bedard could add some much-needed depth to your fantasy rotation. He won't get you a ton of wins, but Bedard can help your team.
