The Cubbies have not been strangers to calling up/recalling players.

Today, they're making yet another move. 

​David Bote has been back and forth this past month between the big time and Triple A. Now, he is being sent back to Triple-A Iowa to make room for lefty reliever Randy Rosario. 

Rosario had a very rough debut last season when he was in Minnesota. He appeared in just two games and had an ERA of 30.86. 

He was ​claimed off waivers by the Cubs in the offseasonThe hard-throwing lefty has posted a dominant 0.57 ERA in 11 appearances at AAA Iowa.

The Cubs are hoping to see that same production at the level he struggled at last season.

With a fastball that can reach 95-96 mph, and a slider coming at you in the high 80's, it'll be tough to get the best of Rosario.

Rosario is hoping that the show won't be so harsh to him this go around.
