Here are three players with low ownership rates who could pay immediate dividends in fantasy leagues:
Chris Iannetta – Colorado Rockies (owned in 3% of Yahoo! leagues)
Iannetta will never have a good AVG and he needs a manager who appreciates his OBP and SLG skills. Jim Tracy is probably not the ideal manager for Iannetta but at least he is back in the majors now and getting some playing time. In his last seven games, Iannetta has 4 HR, 6 R and 8 RBIs. Unfortunately it has taken him 16 days to log those seven games. Due to his poor AVG and sporadic playing time, Iannetta is not an option in all formats. But in any league that starts two catchers, he is worth a flyer.
Vin Mazzaro – Oakland A’s (owned in 2% of Yahoo! leagues)
The estimators are not sold on Mazzaro, as he has a 4.86 xFIP and a 5.11 FIP. But in his last four games, Mazzaro has hurled Quality Starts and he has a 2.30 ERA and a 1.134 WHIP with 2 W in that span. His velocity is down some from a year ago, but Mazzaro is having better success with his fastball in 2010. He also features plus pitches with his slider and curve.
Jonathan Venters – Atlanta Braves (owned in 5% of Yahoo! leagues)
With Billy Wagner having a tremendous year, there is virtually no chance of Venters getting many save opportunities in 2010. But because of his strikeouts, ERA and WHIP, he still has a chance to help fantasy owners. The lefty Venters throws in the mid-90s and has a nice 9.29 K/9. He has a 1.30 ERA, but his xFIP is over two runs higher as he has yet to allow a HR this season. Finally, Venters checks in with a 1.10 WHIP. The WHIP is the shakiest of all, as he has a 4.54 BB/9. But Venters has great stuff, as he complements his heater with a wicked slider. He gets lots of strikeouts and lots of ground balls (63.6 GB%). He’s even picked up 3 W on the season and has a chance to vulture some more going forward with Atlanta’s strong pen.
