SEATTLE -- Chicago White Sox center fielder Luis Robert pulled out of the All-Star Game early Tuesday after undergoing an MRI on his right calf, according to the team's official Twitter account.
Robert, 25, injured himself while participating in the Home Run Derby on Monday night. The team declared him day-to-day in its tweet. He'll be reevaluated before the second half of the season begins Friday when the White Sox take on the Atlanta Braves.
Robert said he doesn't believe the injury is significant.
"I felt tightness in my right calf during the first round of yesterday's Home Run Derby, but it didn't affect my performance in the second round," Robert said.
