"[Navarro's] numbers against left-handed pitching are as good as anybody," Sveum said.
• The Cubs traded right-hander Guillermo Moscoso, 29, who was pitching at Triple-A Iowa, to the Giants. Moscoso compiled a 3.38 ERA and 1.094 WHIP (walks plus hits per inning pitched) with the Athletics in 2011. He was claimed on waivers three times over the winter, ultimately by the Cubs. In 17 starts at Iowa, he was 7-5 with a 3.93 ERA.
• Kris Bryant, the Cubs' first-round Draft pick, hit his first professional home run Friday, one day after going 0-for-5 and striking out five times.
"It felt great to get it out of the way. That first one, no matter what level, is the hardest," Bryant told Boise, Idaho, media after Friday's game. "My parents were here, home debut -- that was pretty fun."
The second player taken overall in this year's Draft, Bryant hit 31 home runs in his final season for the University of San Diego.
"It can only get better from here, and that [first] game might wind up the worst I ever have, so maybe I can look back at it and have a good laugh," he said of the five whiffs.
• Shawon Dunston Jr. was batting .328 at Class A Boise and had more walks (18) than strikeouts (15) in 33 games. That's the opposite of what his father, former Cubs shortstop Shawon Dunston, would do. In his 18-year career, Shawon Sr. struck out 1,000 times and drew 203 walks. Dunston now is a coach on the Giants staff. What gives?
"First, he hits left-handed," said Dunston. "The patience is from my wife."
