Farquhar and his 6 BB/9 in AA is not something that would play well at higher levels. I think he has potential sure; he's rarely given up hits. But the fact that he barely gives up hits and has a high WHIP is just terrible.
Farina has excelled as a reliever and I was hoping he'd get a shot in Las Vegas by year end, although that looks unlikely now. He's had an injury every year since we've drafted him from what I can recall, but he definitely would be a solid bullpen arm if he can stay healthy. His stuff was always better regarded than both Rzep and Mills, who were drafted after him that year.
