Today is Opening Day for the league as a whole, with the Yankees taking on the Nationals at 7:00 PM ET and the Dodgers and Giants facing off after that. For the rest of the league things will get underway on Friday, but today is still a big day as Opening Day rosters must be finalized on Thursday. There aren’t a whole lot of questions as to who will make it for the Red Sox, but there are a few. Among them is who will be on the bench to back up the infielders. According to Jon Heyman, one of them will indeed be Jonathan Araúz.
