Guerrero's transition to second base has been slow but steady. He was signed to a four-year, $28 million contract by a management that expected him to replace Mark Ellis as the starter without playing in the Minor Leagues in the U.S.
"He looked better at the plate his second at-bat," manager Don Mattingly said of Guerrero, who sat out last year before leaving Cuba. "It's his first Spring Training game. We're actually not judging off one game or two at-bats. I'm happy with what I saw.
"We're seeing a guy who hasn't played a while. We'll see what he looks like after a few games. We're not pulling the trigger in this short a time."
Guerrero said he felt comfortable after some initial nerves, calling his first game "a big deal."
