The Chicago Cubs will be without closer Pedro Strop for an extended period after he suffered a hamstring injury Thursday.
According to ESPN's Eddie Matz, Strop said after the game that he was sore and added it would be "at least two weeks" before he can return to the mound.
The injury occurred in the 10th inning of Chicago's 4-3 win over the Washington Nationals. Strop hit for himself and attempted to beat out a double-play, but he was thrown out.
He limped around after the play and was lifted from the game in favor of Randy Rosario.
