Miguel Sano will undergo surgery to repair a meniscus tear in his left knee.

The Minnesota Twins don't have a timeline for his return.

Sano was injured on April 26th celebrating Minnesota's 5-4 win.

Sano returned to play Saturday but left early because of knee pain.

"He did try to play through it but he did something during the course of that game, and we had to take him out," Baldelli said.
