Homer Bailey, CIN - Bailey had a late beginning to his season, not getting his first opportunity to pitch until May 5th (shoulder). But in his three starts, Bailey is 3-0 with an ERA of 1.89 and a WHIP of 1.00. Keep in mind that his three starts have been against Houston (twice) and the Chicago Cubs once, so his numbers are likely to suffer a bit when he plays clubs that can actually hit the ball. Still, he's pitching very well on a club that can put up a lot of runs, so wins should not be a problem. Bailey is owned in less than 45- percent of all leagues.
Ryan Vogelsong, SF - Vogelsong has been getting the opportunities meant for injured starter Barry Zito and has made the most of it. In four starts the 33- year-old has three wins, an ERA of 2.36 and a WHIP of 1.05. He also has 24 strikeouts in 26.2 innings. Vogelsong (13% owned) is likely a temporary solution only as Zito threw off a mound last week and could be back in three- to-four weeks.
Jair Jurrjens, ATL - Jurrjens is still available in one-in-five leagues and if your league is one of those lucky few, you should pick him up immediately. Jurrjens was a surprise in 2009 when he blossomed into a solid No.2 fantasy starter, going 14-10 with an ERA of 2.60 and a WHIP of 1.214. Last year was filled with injuries and should be dismissed as he appears to be back in his old form. In six starts this year Jurrjens is 5-0 with an ERA of 1.66 and a WHIP of 0.992.
Chris Carpenter, STL - Carpenter's ERA and WHIP have been heading in the wrong direction since finishing second in the NL Cy Young race back in 2009. His ERA jumped a full point last year and through nine starts this season in an ugly 4.95. Meanwhile his WHIP has gone from 1.007 in 2009 to 1.179 last season and 1.491 so far this year. He's yielded 21 runs and 42 hits in his past four starts and lost the pin-point control that made him so good. Trading him away while he still holds some fantasy value should be considered.
Madison Bumgarner, SF - Bumgarner was a 14th-round selection who some fantasy owners thought could turn into a solid bargain this season, but that hasn't been the case. In eight starts he's 0-6 with an ERA of 4.25 and a high WHIP of 1.42. He has produced four "quality" starts in a row, but at this point could lose his starting spot when Zito is healthy. I'd hold on to the 21-year-old as his long-term value is still very good.
Matt Garza, CHC - Garza's strikeout total (65 in 49.2 innings) is keeping him in fantasy lineups despite his less-than-satisfactory 2-4 record. He's pitched well in four of his last five starts and you should not panic if you own the 27-year-old former Tampa Bay Ray draft pick. He'll face a tough Cincinnati Reds team on Tuesday who leads the major leagues in runs-per-game (5.32). Perhaps you should sit him this time around and start him again next week. Spot starting a pitcher is not a bad thing, it's prudent.
