"There's a lot of familiar faces in the clubhouse, which is nice," Greene said.
Greene will split playing time at shortstop with Marwin Gonzalez, with Gonzalez getting most of the starts against right-handed hitters. A switch-hitter, Gonzalez was hitting .292 vs. right-handers entering Friday and .119 against lefties. Greene is hitting .245 against lefties.
"I'm excited about this opportunity to join a new ballclub, a new franchise," he said. "I'm just looking forward to coming out here and helping to contribute in any way I can with this team."
Greene, who won a World Series last year with Cardinals, joins an organization that's rebuilding, and he wants to be part of the trend upwards.
"I'm going to bring the work ethic, all the information I learned from the Cardinals organization and try to help out any way I can, and hopefully that's for the present and the future," he said.
