CHICAGO – Geoff Blum doubled in the go-ahead run in the 14th inning and the San Diego Padres defeated the Chicago Cubs 4-3 on Tuesday.

Khalil Greene led off the 14th with a double to the right-field corner against Will Ohman (0-1), and with one out, Blum sent a shot to left that Jacque Jones let skip by him.

Ohman then retired Rob Bowen on a fly to center and pinch-hitter Jake Peavy on a pop to second. But it was the third straight rough outing for the left-hander.

He allowed a three-run homer to Marcus Giles in Monday’s 12-4 win, and he walked in two runs in a 6-5 loss to Cincinnati last week.

Blum’s hit made a winner of Doug Brocail (1-0), who struck out four and allowed one hit in two scoreless innings. Trevor Hoffman pitched the 14th for his third save in as many chances.

Chicago’s Daryle Ward hit a bloop double to center with one out in the bottom of the 14th, but Hoffman got Jones on a flyball to left and struck out Ronny Cedeno to end it.

The Padres loaded the bases in the ninth but failed to score, and two big defensive plays stopped them in the 10th and 12th.

With runners on first and second in the 10th, Brian Giles singled to center off Bob Howry. Felix Pie – making his major league debut for the Cubs – charged in and unleashed a throw that hit Michael Barrett on a fly and beat Russell Branyan by a couple feet. Mike Cameron then grounded out to end the threat.

And with a runner on second in the 12th, second baseman Mark DeRosa dived to his right to snag Marcus Giles’ line drive for the final out.

Adrian Gonzalez tied a career high with four hits for San Diego.

Greg Maddux allowed three runs and six hits in five innings in his first start against the Cubs since they traded him to the Los Angeles Dodgers at the deadline last July. He walked one, did not strike out a batter, but was unable to protect a 3-1 lead.

That evaporated in the fifth.

The Cubs’ Henry Blanco led off with a double to right and scored on a double to left-center by Pie, who was called up from Triple-A Iowa because Alfonso Soriano has a strained left hamstring. Pie scored on Derrek Lee’s single.

Until then, Wade Miller appeared headed to his second loss. He struggled through five innings, allowing six hits and four walks while striking out three after getting hit hard by Milwaukee in his first start.

Chicago’s Aramis Ramirez started at third after missing four games with tendinitis in his right wrist and delivered an RBI triple off the right-field wall in the first inning. But while one star returned, another was missing.

Soriano expects to sit out about a week after straining his left hamstring while attempting a diving catch during the fifth inning on Monday.

The Cubs mulled putting the five-time All-Star on the 15-day disabled list, even though an MRI on Tuesday revealed no major structural damage. Instead, they optioned right-handed pitcher Angel Guzman to Triple-A before the game and called up Pie, a top prospect who batted leadoff.

“I’m upset right now because I like to play everyday,” Soriano said Tuesday morning. “I think I want to be there for them in a week.”

Notes: Gonzalez has five four-hit games. … Cubs manager Lou Piniella said before the game that Ohman simply “needs more work.” The left-hander had a 9.00 ERA in five appearances after allowing a three-run homer by Giles in Monday’s 12-4 win.
