MILWAUKEE -- The Padres traded for infielder Tyler Greene on Tuesday, plucking him from the Braves' Triple-A affiliate in Gwinnett for a player to be named.
Greene, 30, was acquired to give the team organizational depth now that infielder Ryan Jackson has landed on the disabled list with a right wrist strain. Greene will report to Triple-A El Paso.
There's no timetable for Jackson's return, said Padres assistant general manager A.J. Hinch.
Greene was hitting .200 in 41 plate appearances this season for Gwinnett. He's a career .224 hitter in parts of five big league seasons with the Cardinals, Astros and White Sox.
Greene hit 11 home runs in a combined 330 plate appearances with the Cardinals and Astros in 2012.
Greene appeared in 10 games at shortstop with Gwinnett and that's his primary position, although he can also play second base and third base.
Greene was the 30th overall pick by the Cardinals in the 2005 Draft out of Georgia Tech.
Vincent getting noticed as he expands repertoire
MILWAUKEE -- The best kept secret in the Padres' bullpen isn't much of a secret to his teammates or his pitching coach.
Or, quite possibly, the rest of baseball.
Reliever Nick Vincent entered Tuesday's game against the Brewers having retired the last 19 hitters he's faced. He hasn't allowed a hit or a run in his last 6 2/3 innings going back to April 4.
"[His success] is carrying over from last year when he was our go-to guy last year with men on base," said Padres pitching coach Darren Balsley. "He's a huge part of our bullpen, he throws early strikes, there's no fear there and his cutter is one of the best in the game."
But Vincent has certainly evolved into something more than just a one-trick pony since he arrived in the big leagues in 2012.
He ranks fourth in the big leagues in ERA (1.87) among relievers with at least 80 innings since 2014. His 81 2/3 innings can no longer be called a small sample-size.
He's inherited eight baserunners this season and stranded all of them.
In a victory over the Giants on April 19, Vincent struck out the side, getting Buster Posey, Michael Morse and Pablo Sandoval. He got Posey with a cutter and the last two hitters on fastballs.
"His fastball is sneaky, it jumps on guys. The majority of his strikeouts are on his four-seamer. He has an excellent spin rate on his fastball," Balsley said.
"He's using his sinker and changeup more this year. Last year was fastball and cutter. He's starting to expand his repertoire. You can't go up there and sit on one speed, one movement."
Kelly nears rehab assignment after 41-pitch outing
MILWAUKEE -- Pitcher Casey Kelly threw 41 pitches Tuesday in an extended spring training game in Arizona.
"He said he felt great," said Padres' assistant general manager A.J. Hinch, who spoke to Kelly by phone following his outing at the team's Spring Training facility in Peoria.
Kelly, who is regarded as the Padres' No. 4 prospect according to MLB.com, has been working his way back from Tommy John surgery that he had on April 2, 2013.
Kelly will likely begin his rehabilitation assignment with Class A Advanced Lake Elsinore, located about one hour north of San Diego.
Kelly's rehabilitation from Tommy John surgery has gone relatively well and with few hiccups along the way.
He was scheduled to throw to live hitters on April 5 but told the organization that his elbow was a little sore. But he resumed pitching a few days later.
Kelly hasn't pitched in a real game since making a start for the Padres on Sept. 27, 2012, against the Dodgers.
Petco's Green Initiative aims to reduce waste
MILWAUKEE -- The Padres weren't at home Tuesday to celebrate Earth Day at Petco Park, though the team's Green Initiative rolls on even when the team is on the road.
The Green Initiative is a comprehensive, proactive and aggressive plan to save energy and reduce waste.
Every area of Petco Park, which opened in 2004, plays a role in waste reduction through programs such as recycle sorting, food waste composting, plastic wrap and foam diversion and cooking oil recycling.
In 2013, the team exceeded their goal of a 75 percent recycling rate at Petco Park, reaching 81 percent by the end of the year.
The Padres have been named the City of San Diego's Recycler of the Year on four occasions, the last in 2013.
• Fort Wayne infielder Fernando Perez has been named the Player of the Week in the Midwest League. The 20-year-old hit .458 last week for the TinCaps with three doubles, a home run and nine RBIs. Perez is from Otay Ranch High in Chula Vista, which is south of San Diego. He's a native of Ensenada, Mexico.
