The Chicago Cubs returned to Wrigley Field on Thursday on the heels of a 5-1 West Coast trip, looking very much like a team determined to prove its hot start is not a fluke. While it’s easy for fans to get excited about the 11-6 record, how many games will it take for President Jed Hoyer to feel this is who the Cubs really are? “One (hundred) forty,” Hoyer said with a laugh. That would be another 123 games, or well into the playoff race in September.
