Starter Jimmy Nelson was effective into the sixth inning and was in line for the victory – until Milwaukee gave up the lead in a 6-4 loss to San Francisco Wednesday. Reliever Carlos Torres was touched for a double and a home run as the Giants came from behind. Nelson pitched five-and-two-thirds innings, striking out four and surrendering three runs. Hits by Ryan Braun and Domingo Santana helped Milwaukee score three times in the first. Jesus Aguilar stole home. Aguilar also had a solo homer in the fourth inning.
