Rondon throws 'pen session, elbow improving
By Erik Bacharach / MLB.com
PHILADELPHIA -- Cubs manager Rick Renteria said Hector Rondon has been experiencing right elbow soreness, and that factored into Renteria's decision to bring in Neil Ramirez over Rondon in Friday night's save situation.
Rondon threw a bullpen session before Saturday afternoon's Phillies-Cubs game. The reliever tossed 11 pitches, including three breaking balls.
"Didn't have any setbacks," Cubs manager Rick Renteria said. "So we'll see how he feels [Sunday], how he reacts. He looked good."
Renteria added that if Rondon does feel better on Sunday, he could be available to pitch.
The right-hander hasn't pitched in a game since June 6.
"We weren't concerned about it. I think we're just more airing on the side of caution. I think that's the prudent thing to do."
Bonifacio diagnosed with right oblique strain
PHILADELPHIA -- An MRI revealed that Emilio Bonifacio has a right oblique strain.
Bonifacio was placed on the 15-day disabled list on Friday after sustaining the injury in Thursday night's game against the Pirates. Chicago's leadoff hitter fell to the ground after taking a swing in his first at-bat and limped off the field with the support of head athletic trainer PJ Mainville.
"From what we hear, he's feeling actually good," Renteria said. "Hopefully, he's a quick healer."
"Losing Boni is tough, because he can be a catalyst at the top of our lineup," Jake Arrieta said. "He can do so many things. He can slap the ball around and use his speed to get on base. He's also a good defender that can play anywhere. So that's a tough break for us there."
