Edwin Rios: B
The Cubs already had a lot of depth at third base, but now they have a wealth of options with the addition of Edwin Rios. Since Rios bats lefty, he would be the perfect platoon to Patrick Wisdom at third. Although Wisdom has led the Cubs in home runs the past two years, the power-hitting righty struggles against right-handed pitching. Rios could balance out the lineup when the Cubs face a right-handed starter, allowing Wisdom to continue feasting on southpaws.
Coming up in the competitive Dodgers system, Rios has never really gotten a chance at consistent playing time in the Majors even though he is 29 years old. Hopefully, his bat and glove skills prove good enough for the platoon scenario at third base, as Nick Madrigal and Christopher Morel are also vying for playing time at the hot corner.
