Righetti explained that Morris' remaining in Scottsdale was a simple matter of veteran's privilege.
"He's earned the right," Righetti said.
Morris initially might have wished he had made the four-hour round-trip to Tucson. But after allowing two runs and three hits in the first inning -- mirroring his regular-season pattern -- Morris blanked the Brewers on one hit for the rest of his stint. He walked one and struck out two while throwing 62 pitches.
"I felt strong enough to go another inning," Morris said. "Then again, you don't want to overexert yourself."
This, too, was encouraging for Morris. Righetti said that Morris lost 15 to 18 pounds recently when numerous Giants were stricken by the flu, which weakened him considerably.
"He's not going to make any excuses," Righetti said. "So I'm making them for him."
Morris complained that he still lacks command of his fastball, a top priority for virtually every pitcher.
"It's the first and last. It's the only thing, really," Morris said. "Everything else works off that."
"He's got to have that pitch and he knows it," Righetti echoed, pointing out that Morris likes to tantalize right-handed batters with outside fastballs.
Nevertheless, Morris thrived with his curveball, which helped him record nine ground-ball outs.
"Something about it seems to be there," he said.
Despite feeling less than sharp, Morris wouldn't mind beginning the regular season immediately.
"I wish my next start was up in San Francisco," he said. "My pitch count was 60, but I can throw 80 or 90, I'm sure. Spring Training tends to get stale a little bit, whether you're throwing great pitches or not. I want to compete and I want it to count right now."
Left-handers Barry Zito and Jonathan Sanchez threw off bullpen mounds. Following Morris' example, Zito likely will make his next appearance in a Minor League exhibition Tuesday while Russ Ortiz starts that day's exhibition against Texas. ... Righetti said that Sanchez continues to make up for lost time after the 24-year-old endured biceps tendintis. "His arm's in good shape. That's the biggest thing," Righetti said. "He's on his way now." ... Jason Ellison and Todd Linden rank among Cactus League leaders with 17 hits apiece. ... Omar Vizquel is batting .500 (8-for-16) in his last five games.
Expect manager Bruce Bochy to use as many players as possible in Sunday's exhibition against Kansas City in Scottsdale. The Giants have Monday off, so Bochy won't want anybody to get too stale. Left-handers Noah Lowry and Odalis Perez will start for San Francisco and Kansas City, respectively.
