The Chicago Cubs have been one of the best teams in baseball this season, but they might need to make some upgrades to solidify their position in October. It has been a fantastic start to the year for the Cubs, who are in first place in the National League Central and appear to be one of the best teams in the league. From the top to the bottom of the batting order, the Cubs are very good, with two potential NL MVP candidates in the lineup as well. While the offense has been arguably the best in baseball, the pitching staff has had its fair share of issues.
