Starters Tim Hudson and Tim Lincecum are directly responsible for the turnaround. Hudson has established a franchise record by pitching 23 season-opening innings without issuing a walk. Lincecum, whose average of walks per nine innings ranged from 3.2 to 4.4 in the previous four seasons, has issued one free pass in 15 innings.
Nobody else has been scatter-armed, either. Right-hander Sergio Romo attributed the Giants' accuracy to following the game's basics.
"It's less an emphasis on not walking guys and more on making quality pitches," Romo said. "We're not crafty. What you see is what you get. We don't have time to beat around the bush."
The change in Lincecum reflects his increasing reliance on precision instead of power -- though, with 17 strikeouts, he still averages more than one per inning.
"He's not a thrower anymore," Romo said. "He's a guy who goes out there and pitches."
