This thread is about acquiring Escobar, not about "replacing Madrigal". The rumoured Sox interest in Escobar doesn't emanate from a perceived hole at the keystone position. Mendick would be fine, if this team didn't have such a dearth of LH power. Remember, even if the Sox got both Eloy and Robert back, they still would not have a single really big LH power bat. Moncada has not proven to be a big home run threat and Grandal is,....well Grandal. He's a very good OBP hitter, with decent power, but he's not suited to be a #3, or clean up hitter.
If one wants to talk about acquiring someone other than Escobar, please try to limit your suggestions to a LH power hitter. You may disagree, but you can be sure that management is more interested in fixing this roster imbalance, than they are in finding someone to simply play second base. Even if they weren't satisfied with Mendick, they have other internal options. There is Leury, Tim Beckham and even Marco Hernandez. The problem is that none of those guys provide that much needed LH power.
