1- The Sox have gone through a considerable number of infielders due to injuries.
We started with Moncada, Anderson, and Leury. All three have missed time. Next in line were Danny Mendick, Nick Madrigal, Chestlor Cuthbert, and Ryan Goins. Madrigal has missed time due to injury. Mendick is playing every day due to Madrigal and Garcia missing time currently. Goins and Cuthbert suck.
2- In 2020 we are seeing a much higher than normal injury rate across MLB. You need more depth than ever, meaning there is no such thing as too many of these types of players right now. We have already used 7 different IFs. Yolmer would make #8 if he makes it here.
3- A lot of this has depending on health and injuries. There really hasn't been a time this year where the roster has allowed the Sox to run an infield out there with sub-par players on anything other than a single game basis.
