Confident owners may want to stand pat and see how their drafted players pan out before making any major moves. But the season is old enough to make a determination on some guys and injuries happen, too. How to fill the void?

It's time to go bargain-bin shopping. If you own Chris Carpenter, Mike Mussina or Jason Schmidt, you probably have already scanned the free agent pool for some starters.

There are lots of heralded young pitchers such as Felix Hernandez, Cole Hamels and Jeremy Bonderman that are undoubtedly already on a team in your league. They were no secret and were probably drafted at a premium.

But finding young, undrafted pitchers that will contribute can be the difference between finishing first or being in the middle of the pack.

Though it's hard to judge a whole season from just a few starts, UPDATE! recommends some young hurlers who have shown the skills and talent to be very real fantasy contributors. Just don't give up on them after one tough outing.

Last year, I made the mistake of dropping Justin Verlander after he got rocked his next time out. He went from being an undrafted rookie in most fantasy leagues to a fantasy force by season's end. Depending on the size and depth of your league, there's a good chance that these sleepers are still available.

Pittsburgh Pirates
Comment: After his first full season in the majors last year, this 25-year-old showed tremendous growth in his core skills. The 29 homers he allowed last year and the fact that he plays for Pittsburgh may have decreased his value to other owners, but the window of opportunity to obtain this young fireballer is rapidly closing. His 9.0 K / 9, 2.7 BB / 9, and most importantly, his 1.80 ERA this year represent MLB growth for three years in a row. He's only given up 1 HR in 20 IP so far, and if he keeps that up, think Brandon Webb numbers.

Chicago White Sox
Comment: This promising 22-year-old lefty won Chicago's fifth starter spot with a solid spring and impressed Ozzie Guillen with his aggressiveness. In his minor league career, he's consistently posted over a strikeout per inning and has easily struck out twice as many batters as he's walked. So far this year, he's brought his good control to the majors with 10 strikeouts and 3 walks in 11.1 innings. As with any young pitcher, not giving up walks and homers is key. With the potent White Sox offense and a good bullpen behind him, Danks will have some bumpy stretches with ERA, but the Wins, K's and WHIP will be there.

Pittsburgh Pirates
Comment: His hot start so far is no fluke. This 24-year-old lefty's game is inducing groundballs, and his numbers this year reflect that. Throughout his entire professional career, including the minors, he's been extremely stingy with the long ball. He's also exhibited excellent control to the tune of 1.8 BB / 9, 2.75 K / BB ratio, and no home runs allowed. He spent some time in the bigs last year in which he had control issues, but he's corrected that this year and the result is beautiful. His numbers after three games: 2-0, 1.33 ERA, and 0.93 WHIP.

Kansas City Royals
Comment: This 23-year-old has already had his share of Major League experience and is looking to get back on track after missing much of last season due to psychological issues. Whatever his treatment, he seems to have changed for the better. He dominated the spring Cactus League, giving up 8 earned runs, while striking out 27 and walking only 2 in 24 innings. He's continued his comeback in the regular season with two solid starts and one disaster start, striking out 13, walking 4, and giving up only 1 homer in 13 innings. Look past the disaster start and hop on this wagon.

Tampa Bay Devil Rays
Comment: Don't rub your eyes now, but yes, there is hope for Tampa Bay pitching. At 25-years-old, Shields is ready to take the next step into the limelight. The only thing keeping him off fantasy teams is the long ball. Otherwise, he has shown stellar control in the minors and has carried it over to the majors. Last year, he sported a healthy 2.7 K / BB ratio and has improved that to 3.2 this year. Once he solves the home runs, his numbers could skyrocket.
