Hamstring strain to sideline Soriano

CHICAGO -- Chicago Cubs outfielder Alfonso Soriano expects to miss about a week after straining his left hamstring while diving for a ball Monday night against the San Diego Padres.

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 Iowa just before Tuesday's game against the Padres and called up top prospect Felix Pie, who started in center and batted leadoff in his major-league debut.

"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."

Pie went 1-for-4 with a run and RBI and threw out a man at the plate in the Cubs' 4-3 loss to the Padres in 14 innings on Tuesday.

After the game, Soriano was more upbeat.

"I talked to the trainer, and ... I said, 'I feel great. I think I'll be ready before two weeks,'" said Soriano, who might hit in the batting cage on Wednesday.

The Cubs were leading San Diego 3-0 in the fifth inning Monday night when Clay Hensley lofted a fly to shallow center. Soriano sprinted in, dived and rolled over as he trapped the ball.

He then got up and slipped while attempting a throw. Trainer Mark O'Neal tended to him, and Soriano walked off under his own power.

A key component in the Cubs' offseason overhaul, Soriano is batting .245 with no homers and one RBI after signing for eight years and $136 million.

Although Soriano said he was feeling "much better," his status was in doubt until the Cubs optioned Guzman. Manager Lou Piniella spent most of the morning in a meeting with general manager Jim Hendry, assistant general manager Randy Bush and the medical staff.

"I want to do a lot of treatment, a lot of ice," Soriano said.

Pie, batting .444 (16-for-36) with a homer and six RBIs in 11 games with Iowa, learned Monday that he was getting called up.

"It's my dream," he said. "I can't explain how I'm feeling right now."

Guzman is 0-0 with a 2.45 ERA in four relief appearances.
