SAN FRANCISCO - A missed bunt, a couple of errors and a broken-bat single conspired against the Milwaukee Brewers on Monday night. Tyler Thornburg produced another quality start, but his own missed bunt quelled one scoring rally in the Brewers 4-2 loss to the San Francisco Giants. Thornburg went six innings, allowing an unearned run on seven hits. He walked two and struck out four. Thornburg has allowed one earned run on the road through his first five major-league appearances, a span of 21 innings. Hes mostly upset about missing a squeeze bunt in the third that would have put Milwaukee ahead. "Definitely the bunt," Thornburg said. "Thats something I am going to think about all night even though I will try to flush it. I hit in college and its something I pride myself on to get runs for myself. It was buntable." Scooter Gennett, who had tripled with one out, was an easy out. It appeared as though Thornburg bunted right through the pitch. "Its something I am going to work on in the cage before my next start," Thornburg said. Juan Francisco hit a home run and drove in two for the Brewers, who have lost four of five. Jean Segura and Jonathan Lucroy each had two hits. "We had opportunities and we didnt come through," Brewers manager Ron Roenicke said. "There were a couple of missed calls that hurt us and they got a couple of breaks." Errors by Francisco and Jeff Bianchi allowed the Giants to score three unearned runs on the night. Jeff Francoeurs broken-bat single in the bottom of the eighth inning drove in the go-ahead run. "I dont know how he missed that one," Roenicke said of Gregor Blancos grounder that went under Bianchis glove, allowing two runs to score. "Hes a good fielder and he does make those plays. When it goes bad, it surprises you." John Axford (4-5) took the loss after walking two of the three batters he faced. The only out was a drive by Buster Posey to the deepest part of the park. "You never want to put the first runner on in a tight ballgame like that," Axford said. He walked Hunter Pence, who stole second, to start the inning. After Poseys at bat, Axford walked Pablo Sandoval intentionally, throwing wildly on the fourth ball to allow Pence to reach third. "Ive never done that before in my life," Axford said. "The ball, even before I was throwing it, was slipping out of my hand. I tried to compensate some way and I just air mailed it." The Giants had runners in scoring position in each of the first four innings and were 0 for 9 in those situations. They were 1 for 13 overall. In the fourth, Blanco hit a sharp grounder to Francisco at first, who threw the ball into left field trying for the out at second, allowing the first run to score. The Brewers evened things in the seventh, with Franciscos ground-rule double driving in a run. Javier Lopez got pinch hitter Rickie Weeks to ground into a double play with the bases loaded in the seventh to preserve the tie. "I was arguing with him," Weeks said. "I thought I had it. He doesnt mean to miss a call and you cant blame the umpires. There are no excuses in this game." Francisco added a solo shot in the ninth.
