We're going back to Junior Caminero again today. He's a strong bet against right-handed pitchers, with 28 of his 39 HRs coming against them. Nationals' SP Brad Lord has been solid as a reliever but more vulnerable as a starter, giving up 7 HRs in 13 starts and allowing a .280 batting average when starting compared to .217 in relief. We set Caminero's line at +215 to homer.
