The Chicago Cubs acquired Nicholas Castellanos as a rental at the trade deadline of the 2019 season. They ended up missing the playoffs so it was all for not but now he is a free agent to be. He went there from the Detroit Tigers where he was a noted White Sox killer. He loved playing against them because he always played well against them. The Cubs almost did the White Sox a favor by getting him out of the American League Central. Now he looks for a new home and you can claim that the White Sox would be a perfect fit.
Castellanos is a really good hitter and his time with the Chicago Cubs proved that. He had a 2.7 WAR, 27 home runs, 73 RBIs, and 100 runs scored split between the Detroit Tigers and Chicago Cubs in 2019. He also slashed .289/.337/.525 so there is little doubt that he is very good at the plate. If he could bring some of that to the Chicago White Sox lineup it would go a long way.
You saw the increase in production when he left the Tigers for the Cubs and that could be because of the talent he was hitting around. With players like Anthony Rizzo, Kris Bryant, and Javier Baez in the lineup around him that makes it easier. He would be coming into a similar situation with the White Sox with guys like Tim Anderson, Jose Abreu, and Yoan Moncada around him. He also wouldn’t have to move very far off the field so it could be a fitting transition.
All of these guys are good baseball players. They would all be good in rightfield for the White Sox because they haven’t had much better over the years. It is a position of need so anyone of them would go a long way in this team being even better.
