The fifth spot remained undetermined as Matt Cain strives to condition himself enough to be able to pitch at least five innings on April 8 against the Dodgers. If Cain isn't ready in time -- his progress was delayed by removal of a cyst on his pitching arm -- Chris Heston likely would replace him in the rotation.
• Compared with previous performances by Giants starting pitchers, Cueto's outing against Kansas City seemed like a gem. He lasted six innings while surrendering three runs and eight hits. Demonstrating command, he struck out six and walked none. "I felt really good, really comfortable," Cueto said through an interpreter. "Everything was working."
Said Bochy, who had watched his projected regular-season rotation record a 9.97 ERA entering Friday, "It's nice to get a quality start. It's been a rough go. It's time to tighten things up, and this is a good start."
