It seems like the Cubs spend all their time either talking up the future or trying to sell memories of Wrigley Field. That’s why Theo Epstein should put his quote up on a big banner above the marquee as a reminder: “LOSING SUCKS.” “IT’S THE PARTY OF THE CENTURY,” they keep telling everyone, at a time when the United Center is rocking for the Bulls and Blackhawks and the Cubs are a last-place team working on a title drought that’s at 105 years and counting. A rebuilding project that has no timeline will enjoy Wrigley Field’s 100th anniversary celebration. A media advisory signaled team representatives would be available on Wednesday for live shots beginning at 5 a.m. The president of baseball operations must have enjoyed Tuesday night’s 9-2 victory over the Arizona Diamondbacks. Jason Hammel (3-1, 2.60 ERA) again looked like he will become an attractive trade chip. Mike Olt hit a three-run bomb into the right-field bleachers and is grabbing hold of the third-base job. Javier Baez is at Triple-A Iowa, Kris Bryant is at Double-A Tennessee and the Cubs will add another impact player to their deep farm system with the No. 4 overall pick in the draft. But in Year 3, the big-league product has a payroll around $75 million and is still nowhere close to those Boston Red Sox teams Epstein helped build into a perennial contender. “Nothing related to losing ever gets easier,” Epstein said. “Losing sucks. When losing stops sucking, you should probably find another career.” MSNBC’s “Morning Joe” will broadcast live from Wrigley Field on Wednesday morning, hopefully getting into all the financial issues and political fights that have delayed the renovation. Bud Selig is supposed to be there, and maybe the commissioner can shed some light on why Major League Baseball approved the terms Sam Zell’s Tribune Co. demanded from any buyer before the Ricketts family entered into a highly leveraged partnership in 2009.
