Willie Bloomquist singled in the go-ahead run with two out in the 13th inning, and the Seattle Mariners beat the Cubs 5-3 on Tuesday night in Chicago for their season-high fifth straight win.
All of the wins in the streak have come in their final at-bat, and the latest occurred after Chicago's Michael Barrett drove in Derrek Lee with a single to tie it at 3 in the eighth.
The winning rally started when Jose Vidro knocked a double off the ivy in left field with two out. After Will Ohman (0-4) intentionally walked Yuniesky Betancourt, Bloomquist grounded a single to right and Vidro beat Jacque Jones' two-hop throw to the plate.
Ohman intentionally walked Ichiro Suzuki, and Jamie Burke lined a single off first baseman Lee's glove to drive in Betancourt.
Eric O'Flaherty (3-0) pitched 2 2/3 scoreless innings for the win. J.J. Putz pitched the 13th for his 19th save in as many chances, but it didn't come easily.
Ryan Theriot and Felix Pie singled with one out, putting runners on first and third. Mike Fontenot then lined out softly to second, bringing up Alfonso Soriano - the centerpiece of the Cubs' $300 million makeover in the offseason.
He walked, loading the bases for pinch-hitter Koyie Hill, who grounded out.
Lee led off the eighth with a double off reliever Sean Green and Barrett tied it with a single off the glove of diving second baseman Jose Lopez. Mark DeRosa followed with a double to right-center that put runners on second and third and chased Green.
Brandon Morrow came in and intentionally walked Cliff Floyd to load the bases, before Theriot forced a runner at the plate for the first out. George Sherrill then caught Pie looking at a 3-2 pitch on the inside edge and struck out Mike Fontenot on four pitches to end the threat.
