The Cubs' future will be on display Tuesday with Starlin Castro and Darwin Barney in the spotlight. For Castro, the day is expected to bring the signing of a seven-year, $60 million contract that will lock him up as a team cornerstone for the Theo Epstein era. For Barney, the day could bring a National League record-tying event should he play another errorless game. Barney played his 112th consecutive errorless game at second base Monday in an otherwise disastrous 15-4 loss to the Milwaukee Brewers. The NL record for second basemen is 113 set in 2010 by David Eckstein of the San Diego Padres. Cubs manager Dale Sveum already has endorsed Barney for Gold Glove honors.
