SAN DIEGO -- In the interest of accuracy, first-year Padres general manager A.J. Preller's first acquisition was left-handed Minor League pitcher Kyle Bartsch from the Royals on Nov. 20.

But in terms of significance and impact, the deal Preller struck early Thursday, landing outfielder Matt Kemp from the Dodgers as part of a five-player swap, created a much larger seismic tremor in terms of importance.

The Padres will receive Kemp and catcher Tim Federowicz in exchange for catcher Yasmani Grandal, pitcher Joe Wieland and Minor League pitcher Zach Eflin, a baseball source told

USA Today first reported the deal and indicated that the Dodgers would send approximately $31 million of the remaining $107 million left on Kemp's contract to the Padres. Because of the money involved, the trade will need the approval of the Commissioner's Office. Physical exams also will need to be taken.

The trade has yet to be confirmed by either club.

Preller was hired in August and immediately charged with upgrading what was baseball's worst offense in 2014.

This was a deal the Padres and Dodgers kicked around for weeks, one that continued this week at the Winter Meetings in the Padres' backyard, just down the road from Petco Park. Late Wednesday, it finally came to fruition.

Kemp has a career .322/.372/.495 line, with 14 doubles, seven home runs and 34 RBIs, in 234 plate appearances at Petco Park. He immediately becomes the middle-of-the-order bat the Padres have been seeking -- something they haven't had since Adrian Gonzalez was with San Diego from 2006-10.

In addition to Kemp, the Padres get their backup catcher in Federowicz. The 27-year-old is a career .194 hitter in parts of four big league seasons, though his forte is game-calling and defense. He'll serve as the backup to Rene Rivera, who had a breakout season in 2014.

Wieland, 24, missed the entire 2013 season while recovering from Tommy John surgery. He returned in 2014, going 1-0 with a 7.15 ERA in four games. Last week, he avoided salary arbitration by agreeing to a one-year, $590,000 contract.

Eflin is a 20-year-old right-hander who was the 33rd overall pick in the 2012 First-Year Player Draft. He has a 3.41 ERA in his first 50 professional games (49 starts) and would have likely began the season in the Double-A Texas League. He was rated the 10th-best prospect in the Padres' system by

Kemp, who turned 30 in September, is owed $107 million over the next five seasons, during which he's to make a shade more than $21 million annually through 2019. He fits exactly what Preller has been looking for -- not just offense, but a cost-controlled player.

Grandal essentially became expendable due to the breakout year catcher Rivera had in 2014, and that many pitchers on the staff preferred pitching to him.

Grandal, a switch-hitter, had major surgery on his right knee in August 2013 and only caught 76 games this past season while hitting .225 with 15 home runs and 49 RBIs. He was able to catch more this offseason and expressed interest in doing more in 2015.

There is no shortage of interesting ties between the Padres and Dodgers as they relate to Grandal and Kemp.

It was former Padres GM Josh Byrnes who traded for Grandal as part of a five-player deal with the Reds in December 2011. Byrnes, dismissed in June, was hired by the Dodgers in November to be their senior vice president of baseball operations.

As for Kemp, he was drafted by the Dodgers by then-scouting director Logan White, who in October became the Padres' professional scouting director and senior advisor to Preller.

Preller indicated on Monday that the team was looking for "guys in a perfect world who would be a fit for us in a long-term type setting."

They have that control in Kemp, who the Padres are now on the hook for the last five years and roughly $75 million of his existing contract, representing the largest contract obligation in club history.

Kemp is coming off a big second half during which he hit .309/.365/.606 with 17 home runs and 54 RBIs in 263 plate appearances. That kind of production mirrored the kind he gave the Dodgers before hamstring and ankle injuries limited him to a combined 179 games in 2012-13.

The deal figures to be the first of at least two the Padres will make to improve an offense that ranked last in just about every pertinent offensive category a year ago.
