08:13 AM ET 01.18 | Javier Baez will arrive with great expectations in Chicago, and the public is watching. [Baez] will get a chance to line up with current and former players Friday during the opening ceremony of the Cubs Convention, sealing his status as one of the faces of the future. ... [Jason McLeod] said the young players are getting a crash course in how to be responsible on and off the field, which includes dealing with "the media, dealing with social media and watching what they put on Twitter." ... One low-level Cubs prospect deleted his Twitter account this week with no explanation. The same player was instructed by management earlier this winter to delete an inappropriate tweet. McLeod acknowledged the Cubs brass monitors what its players say on social media.
