The late, great Yogi Berra once said that “it ain’t over till it’s over,” but……..

After the Giants’ bullpen blew yet another lead and was directly responsible for their second loss in a row, a 5-4 walk-off defeat at the hands of the San Diego Padres, the team is in a near-impossible spot right now.

A night after Jake Peavy was victimized by his relievers after a dominant performance, Madison Bumgarner was denied his 19th win of the season after going seven strong innings and leaving with a 4-3 lead.

Sergio Romo took the ball in the eighth but gave up a run-scoring double to Matt Kemp, the second time in as many nights that he has surrendered a lead.

In the ninth, Michael Broadway took over for Romo and promptly yielded a leadoff double to Derek Norris, and then after Melvin Upton, Jr. sacrificed pinch runner Travis Jankowski over to third, Alexi Amarista sent one near the warning track in left to bring in Jankowski and send the Giants packing.

“It shows you how tough it is to get a win sometimes,” Bochy said of Bumgarner. “He did all he could. (But) give (the Padres) credit, they fought back and had a couple of big hits.”

To make things worse, the Dodgers came back from an early deficit to beat the Arizona Diamondbacks, and by virtue of their win the Giants’ loss, their magic number to clinch the National League West is down to three. Meanwhile, the Chicago Cubs are one win – or one Giants loss – away from locking up the final NL wild-card spot.
