LOS ANGELES -- That blockbuster trade 16 months ago wasn't supposed to turn out this way. At the time of the December 2014 deal that sent Los Angeles Dodgers second baseman Dee Gordon, pitcher Dan Haren and infielder Miguel Rojas to the Miami Marlins, it seemed Enrique Hernandez was just a throw-in piece among the four players that arrived from Florida.

The nugget was supposed to be left-hander Andrew Heaney, who was immediately dealt to the Los Angeles Angels for veteran second baseman Howie Kendrick, the player the Dodgers really wanted.

It turns out the Dodgers struck gold with Hernandez, who hit two solo home runs Friday night and added a two-run double off San Francisco Giants ace left-hander Madison Bumgarner, leading the Dodgers to a 7-3 victory in front of a sold-out crowd at Dodger Stadium. Hernandez came into the game with the highest batting average of anyone in the majors with at least 100 at-bats against left-handers (.379) and continued his mastery against Bumgarner, both a three-time NL All-Star and World Series champion.

After entering the game 7-for-13 with three doubles and a home run off Bumgarner in his short career, Hernandez slammed the first pitch of the game from the lefty over the fence in center field for a 451-foot home run. He lit up Bumgarner again in the third inning with a shot to left that traveled a similar distance, giving the Dodgers a 2-1 lead.

Hernandez then capped off a sloppy fourth inning by the Giants with a bases-loaded, two-run double over the third-base bag for a 6-1 advantage. The Giants should have been out of that inning, but shortstop Kelby Tomlinson, who booted a potential game-ending double play last weekend in an extra-inning loss to the Dodgers, fumbled an even easier grounder off the bat of catcher A.J. Ellis with runners on first and second and one out.

Charlie Culberson then delivered a two-run single to right, and second baseman Joe Panik botched a flip to second on another potential double-play grounder by starting pitcher Clayton Kershaw, bringing Hernandez to the plate with the bases loaded.

It was the second straight night Hernandez lifted the Dodgers to victory. His two-run double in the seventh inning Thursday against the visiting Arizona Diamondbacks gave Los Angeles a 3-2 lead in their eventual 5-2 victory.

While the score was still close in the series opener against the Giants, Kershaw fell into his lone jam in the third inning, but it was only partly his fault. He surrendered a one-out single to Bumgarner and No. 9 hitter Gregor Blanco then hit a grounder to the left of Kendrick at second. He spun to throw out Bumgarner, but dropped the ball in the process and then threw late to first.

Angel Pagan then hit a grounder to the right of diving first baseman Adrian Gonzalez, but the ball got under his glove, loading the bases. Kershaw appeared on the verge of escaping the jam after getting Panik to foul out to third, but he threw a wild pitch that nearly hit Buster Posey in the head, scoring Bumgarner from third. The Dodgers avoided further damage when Hernandez made a diving catch in left field to rob Posey of at least one RBI.

Kershaw needed 93 pitches to get through six innings, but hit for himself in the bottom half of the inning and reached on another error by Tomlinson, which ended the night for Bumgarner with Hernandez coming to the plate.

Kershaw (2-0) was finished after seven innings, allowing three runs (two earned), five hits and striking out six with no walks. He did allow two runs to score on wild pitches.
