Maddon has done it a few times this year. I thought with the offense struggling, the Cubs could use his bat. Coming after an off day, it seemed like the perfect situation to use Contreras in the OF. Sorry you disagree. Sorry you haven't been watching the Cubs this year. Sorry for referencing something the Cubs have been doing this year.
I am not disagreeing, it was 10 innings this year. You keep at this like he played 20 games out there. Was that the one game you watched this year? The first 1.2 innings was when Maddon had Caratini at third and Willson catching. Caratini made a bad throw on a double play, they moved Caratini behind the plate and put Willson in right field with no other option other than pitcher. Then they tried one more game, he made a nice throw in the 8th, was way out of position and had to run where a second baseman not named Descalso would have caught the ball, just to run 200 feet, over run the ball and miss it, leading to Kimbrel blowing the save, oh, and dont forget, end up with a foot injury that put him on the IL days later.
You want his bat in the lineup, he needs to stay healthy. Running bases and 40 feet around his position is different than chasing balls in the outfield. That means he needs to stay off the IL too. Its not the fantasy or video game you seem used to.
