CINCINNATI -- Cubs outfielder Ryan Sweeney left Tuesday's 3-0 win over the Reds in the second inning with a strained left hamstring.
Sweeney was injured while running out a ground ball he hit up the middle to lead off the second, on which Cincinnati shortstop Zack Cozart made a pretty spinning throw to get Sweeney at first base.
"We'll see how he is tomorrow," manager Rick Renteria said. "I think we'll wait until tomorrow to see how it shakes out."
Rookie Matt Szczur replaced Sweeney in right field in the bottom half of the frame.
