PITTSBURGH — The Cubs put infielder Matt Duffy on the 10-day injured list, retroactive to Sunday, with a strained muscle in his lower back before their game Tuesday against the Pirates. They selected the contract of infielder Patrick Wisdom from Triple-A Iowa to take Duffy’s place on the 26-man roster.
Duffy last played Saturday against the Cardinals but was removed from the game because of the back issue and was replaced by David Bote.
Duffy has been part of the Cubs’ offensive success this season and seemingly has come up in big spots for them all season. He is slashing .278/.377/.356 with a home run, 12 RBI and three stolen bases.
To make room for Wisdom on the 40-man roster, the Cubs designated right-hander Jason Adam for assignment.
Contreras doing fine
Manager David Ross thought the worst when he saw catcher Willson Contreras take a 99 mph fastball from closer Craig Kimbrel off the left wrist Sunday against the Cardinals. But Contreras is feeling fine and just has a bruise.
Contreras didn’t start Tuesday against the Pirates, but he did take batting practice without any protective equipment on his left forearm. He is slashing .245/.352/.439 with eight homers and 22 RBI.
‘‘He’s doing all right,’’ Ross said. ‘‘He woke up this morning feeling much better. We got him looked at [Monday]. The X-rays were negative. I think everybody is encouraged with where he’s at.
‘‘Willson means a lot to this team. I think the everyday catcher . . . is just a vital, vital piece that interacts with not only the pitchers but the opposing hitters and where their holes might be and how they’re taken advantage of.’’
