CHICAGO -- The Chicago Cubs were pummeled by the San Diego Padres on Thursday at Wrigley Field. Here’s a quick look at the contest:

How it happened: For the second night in a row, the Padres jumped out to an early lead on the Cubs. After quickly retiring the first two batters of the game, Edwin Jackson gave up a bloop single to Seth Smith. Yasmani Grandal followed with a hard-hit ground ball down the right-field line for an RBI triple. Grandal came around to score on Will Venable's broken-bat single to put San Diego up 2-0 early. The Cubs cut the lead in half with Luis Valbuena's RBI single in the fourth, but the Padres got the run back almost immediately on Rene Rivera's solo home run in the top half of the fifth. The Padres broke the game open with a nine-run sixth that saw 14 batters come to the plate and went on to defeat the Cubs 13-3.

What it means: Jackson went five-plus innings and gave up five runs (four earned) on seven hits while striking out four and walking one. Jackson was having a relatively solid outing but allowed the first two men to reach in the sixth before being removed with cramping in his right hand. Both men came around to score in the Padres' big inning. Jackson, who still has two years remaining on his four-year, $52 million deal, is having another rough season for the Cubs and saw his ERA balloon to 5.68.

Outside the box: A pair of top prospects made their debut Thursday night after being promoted a level. Albert Almora went 0-for-4 with a strikeout in his first game at Double-A Tennessee. Jorge Soler fared better in his first game with Triple-A Iowa, going 1-for-3 with two walks.

Up next: The Cubs open a three-game set with the St. Louis Cardinals at Wrigley Field on Friday at 3:05 p.m. CT with Travis Wood taking the mound against Joe Kelly.
