Navarro was hurt in a home-plate collision with the Philadelphia Phillies’ Chase Utley on Wednesday. The Cubs called up catcher J.C. Boscan from Triple A Iowa before knowing how long Navarro will be out.
The injury to Navarro has focused attention on the fact the Cubs do not have many prime prospects at catcher in their farm system, something general manager Jed Hoyer acknowledged when speaking with the media before Friday's game.
"When I study our minor league system, for the most part at almost every position on the diamond you can find a pretty good prospect," Hoyer said. "Catching is an area where we are thin. We know it. We talk about it all the time, how do you acquire catching?
"It's going to be a priority over the next couple of years to find a lot of catching. We've made pitching a priority the last couple of years. I feel a lot better about our pitching than I did a year ago.
"Catching is the most important defensive position on the field. When you get that front-line type guy you are spoiled. We're going to have to be creative how we go about it."
DeJesus in cleanup spot: Being creative also is a requirement for manager Dale Svuem when it comes to filling out his lineup card these days.
For the first time in his 11-year career and 1,230 games, David DeJesus found his name In the cleanup spot Friday. It is the only spot in the batting order where he has never started a game.
"I figured it," Svuem said. "I've got to give (Nate) Schierholtz some days off because we are not facing any lefties. I have to pick and choose my days off.
"Right now (DeJesus) is a viable guy to protect (Anthony) Rizzo a little bit, and it just added up that way. (Junior) Lake has done well leading off. The lineup tight now is something we've got to piece together day to day."
More injury updates: Hoyer said pitcher Matt Guerrier has a flexor mass injury that likely will require surgery.
Outfielder Jorge Soler, recovering from a fractured left shin, will be in Chicago on Monday to be examined by the Cubs doctors. Soler is on the roster of the Single-A Daytona and has been out since the middle of June. Hoyer said he will know more about when Soler can return to Daytona lineup after the results of that examination.
It is possible Soler could also play in the Arizona Fall League as a way to make up some of the at-bats and games he has missed this summer.
Outfielder Albert Almora, playing at Class A Kane County, likely is a week or 10 days away from being activated from the DL, Hoyer said. Almora has missed the last week with a groin injury.
It also is possible that Almora will be one of the players assigned by the Cubs to the Arizona Fall League. That roster has not yet been set.
Pitcher Scott Baker, recalled from a rehab assignment on Wednesday after he had three starts postponed by rain, likely will go back on another rehab assignment next week, Hoyer said. Baker is recovering from Tommy John surgery.
