PHOENIX -- Mark Buehrle wouldn't mind matching this outing during the regular season.
"I wish I could have bottled it up so I could feel even half as good on opening day," said Buehrle, who will be on the mound for his ninth season-opening start Friday when the White Sox play at Cleveland.
Most surprising to Buehrle were his seven strikeouts, five more than he had in his four starts combined entering Sunday's game.
"It seems like I get ahead of guys and can get two strikes with the best of anybody," Buehrle said. "I just don't have that put away pitch."
Estrada, who came over from the minor league camp to start for the second time, allowed two runs on seven hits and a walk. He struck out four.
Estrada is a candidate to fill in as a spot starter with right-hander Zack Greinke opening the season on the disabled list with a broken rib even though he won't break camp with the team.
"He commanded his fastball well," Brewers manager Ron Roenicke said. "It looks like it's a sinking fastball and he pitches down in the zone to guys."
Estrada appeared in seven games for Milwaukee last season, starting one, and had no record with a 9.53 ERA.
"He's not going to be intimidated over anything," Roenicke said.
Before the game, the Brewers acquired Washington CF Nyjer Morgan, two days after trading Chris Dickerson to the Yankees. Roenicke said Morgan will back up Carlos Gomez and also serve as a pinch-runner. To make room for Morgan, the Brewers informed OF Brandon Boggs that he will not make the club. Since Boggs is out of options, the team is hoping he will clear waivers and be able to report to Triple-A Nashville. Milwaukee also optioned RHP Justin James to Nashville. White Sox RHP Jake Peavy threw a 30-pitch bullpen session on the back fields at the White Sox's spring complex in Glendale, his first work from a mound in a week. Peavy is expected to remain in Glendale for extended spring because of tendinitis in his right shoulder. He last pitched on March 19, throwing 5 2/3 innings against Oakland. Nineteen Brewers players, along with Hall of Famers Robin Yount and Bob Uecker, signed autographs before the game and raised $4,600 for the American Red Cross' relief efforts in Japan following the earthquake and tsunami earlier this month.
