EDGE Analysis

Shields, who was making his first start in over two months because of a shoulder injury, allowed just one run through his initial five frames. He got the first two men in the sixth but faded a bit as he proceeded to walk Troy Tulowitzki before Russell Martin launched a two-run home run to chase him from the game. Shields worked up to 86 pitches and was in the strike zone at a 66 percent clip -- two positive signs after such a long layoff -- and he will look to build on an encouraging return to the mound Saturday against the Athletics.
