Rapid Reaction: Cubs 4, Giants 3

CHICAGO -- Here's a quick look at the Cubs' 4-3 win over the San Francisco Giants on Friday:

How it Happened: After a stellar 7.1 innings by Carlos Villanueva, the Cubs looked poised to even the series. But once again, the Cubs' bullpen blew it, and Carlos Marmol wasn't to blame this time. Kyuji Fujikawa inherited a 2-0 lead to start the ninth, and he proceeded to yield three hits and three runs. But Starlin Castro, who homered earlier in the game, lifted an RBI hit in the bottom of the ninth to drive in David DeJesus with the winning run. DeJesus is 7-15 in his last three games, with three doubles and one homer.

What it Means: In lowering his ERA to 0.64 Villanueva is showing he belongs in the rotation. He got 11 ground outs by keeping the ball down on a day where the wind was blowing straight out. It's early but Villanueva is proving to be a nice pick up.

Under the Radar: Steve Clevenger made the first start of his career at third base but didn't touch the ball until the sixth inning, then he made three plays in a row including one on a slow roller by Buster Posey. Anthony Rizzo struck out his first three times up and fourth in a row overall going back to Thursday's ninth inning, before he lined out in the 7th inning on Friday.

What's Next: The four-game series continues on Saturday with Jeff Samardzija on the mound for the Cubs. Game time is 12 CT.
