Shields (7-1) allowed four runs on eight hits and four walks while striking out five in a 4-2 loss to the Diamondbacks on Friday. Walks continue to haunt Shields, as he's handing out passes at a career-high rate. He's also giving up homers at a career-high rate, so it's amazing that it took Shields this long to record his first loss for the underachieving Padres. If he can't maintain his strikeout rate (also a career high), he might be a good candidate to sell high on at this point, considering his high WHIP and weak peripherals. Shields will make his next start in San Francisco on Thursday.
