Cubs right-hander Kyle Hendricks will make his scheduled start against the Miami Marlins on Sunday, but the team is concerned about the veteran's start to the season.

Hendricks, 34, is 0-2 with a 12.71 ERA over four outings that includes a league-high seven home runs allowed.

"It's not one or two starts," Cubs president of baseball operations Jed Hoyer said Friday morning. "It's been four, so I think there is a level of concern, but I would also say, given his track record and given the fact that he's gotten through some struggles in the past, this isn't the first time he's struggled. No one pitches in the big leagues and doesn't have those struggles at some point."
