Raikkonen pitted after the 25th, a quick 8.6-second stop that allowed him to come out ahead of Alonso, who pitted on the 27th and slipped back into the pack.
Schumacher, starting from No. 8 on the grid, began to make up time midway through the race, where he turned back-to-back quickest laps -- moving him temporarily into second place -- before pitting after 32.
His race began to break down after 44 laps, when he pitted to replace a blown left rear tire. Two laps later, he went out with the problem to his left front.
It was Schumacher's second retirement in the last three races with mechanical problems. His last retirement with a mechanial problem -- prior to this year -- came in 2001. It also ended his string of four straight wins in the Spanish GP.
