Delmon young, i drafted sixth? fifth? dropped him 3 weeks ago and haven't looked back.
barney has been in a bit of a slump for the last two or three weeks; seems they're letting him play through it though (like they did his early may slump) and if he gets out of it, he's a consistent player (and eligable at ss too!). no power, but consistent AVG at the top of their order. he is a true rookie though, so he may be getting where he needs to elevate to the next level in regards the pitching he's facing.
Danny Espinosa on the nats has been tearing it up at second (not a bad line-up either what with werth and morse in there). Espinosa has some power too.
Justin Turner from the mets might be another power option at second (and third, if'n you need him there), but i've never used him....playing against my brother in three leagues where HE has him.
