How it happened: The Padres got out to an 8-0 lead before the Cubs got on the board. San Diego scored two in the second on three straight hits, added one in the third on a sacrifice fly, then batted around in the fifth when they produced six hits and five runs. Yonder Alonso homered that inning as did Carlos Quentin in the next. Eight runs were charged to Edwin Jackson as he failed to get out of that fifth inning. The Cubs put a four-spot on the board in the bottom of the fifth with home runs by Luis Valbuena and Starlin Castro. David DeJesus also homered in the seventh. San Diego's Nick Hundley added a three-run blast in the eighth inning that landed onto Waveland Ave. and the Cubs' Cody Ransom went deep in the ninth.
What it means: It’s really the first time this season the Cubs weren’t in the game until the end and that’s thanks in part to their $52 million investment in Jackson. He’s been anything but a good value through the first month. His location was awful and he failed to battle through any rough innings as his ERA rose to 6.27. It’s hard to know what the issue is, but hopefully it’s not complacency after finally getting a big contract and bouncing around for so many years. The rest of the starting staff has been more than adequate, it’s time for Jackson to earn his keep.
Outside the box: The Cubs' string of 25 consecutive games decided by four runs or less was snapped. ... Valbuena eclipsed his home run total of last season, hitting his fifth on Tuesday, while the Cubs finished the month with 35 long balls overall. They hit only nine home runs last April. ... The DeJesus home run hit the LED board over the fence in right field and needed to be reviewed after initially being called a double.
