Braves send Justin Upton to San Diego

San Diego, CA (SportsNetwork.com) - The San Diego Padres continued what has been a whirlwind week with Friday's acquisition of two-time All-Star outfielder Justin Upton from the Atlanta Braves.

Upton, a National League Silver Slugger Award recipient in 2014, heads to the new-look Padres along with minor league pitcher Aaron Northcraft, with the Braves receiving a package of four prospects for the impending free agent.

San Diego sent pitcher Max Fried, the team's first-round pick in the 2012 draft, to Atlanta along with infielders Dustin Peterson and Jace Peterson and outfielder Mallex Smith.

Upton, who drove in a career-best 102 runs while belting 29 homers and hitting .270 last season, joins fellow new acquisitions Matt Kemp and Wil Myers in San Diego's overhauled outfield. Kemp was officially obtained from the NL West rival Los Angeles Dodgers on Thursday, with the 2013 AL Rookie of the Year Myers coming over from Tampa Bay as part of a three-team, 11-player swap that was finalized earlier Friday.

Padres first-year general manager A.J. Preller pulled off another trade for a hitter on Thursday, landing catcher Derek Norris from Oakland for young pitchers Jesse Hahn and R.J. Alvarez.

The first overall pick in the 2005 draft, Upton spent his first six major league seasons with the Arizona Diamondbacks before being dealt to Atlanta -- where he played alongside his brother, B.J. --- prior to the start of the 2013 campaign.

Upton has averaged 25 homers and 80 RBI since 2009 and owns a .274 career average, while his 10 long balls at Petco Park are tied for the most by a visiting player in the stadium's history.

Those numbers should bring a boost to a Padres' offense that was the worst in the majors last season, placing last in runs scored (535), batting average (.226) and on-base percentage (.292).

Fried, the seventh overall pick of the 2012 MLB Draft, figures to be the centerpiece of the deal from the Braves' standpoint. The 20-year-old lefty entered last season rated as the No. 53 overall prospect by Baseball America, though he pitched just 10 2/3 innings before undergoing Tommy John surgery in August.

Jace Peterson hit .307 with 24 doubles over 86 games between Double and Triple A last season, but went just 6-for-53 at the plate with the Padres in his first taste of the majors.

Dustin Peterson, a second-round selection of San Diego in 2013, spent last season at Low Class A Fort Wayne and hit .233 with 10 homers, 79 RBI and 31 doubles in 126 games.

Smith is best known for his speed, having led the minors with 88 stolen bases while splitting last season between Fort Wayne and High-A Lake Elsinore. The 21-year-old combined to hit .310 with five homers and 31 RBI over 120 games.

Northcraft posted a 7-3 record with a 2.88 ERA in 13 games (12 starts) with Double-A Mississippi, but struggled in a climb up the ladder. In 13 appearances (12 starts) with Triple-A Gwinnett, the right-hander went 0-7 with a 6.54 ERA.
