Below is a link to the cluster that ended with Mack leaving. He was not a platoon player. I believe he got hurt during 1993 and also missed the first 30 games in 1994. He was having a monster year before the strike was called. Mack was 2nd in WAR in 1991 only to Tapani. He was 2nd only to Puckett in 1992 and he was 2nd only to Knoblach in 1994 and only because he played 28 fewer games. He was on pace for a 7.8 WAR over 162 games. Keep in mind those teams had Knoblach, Puckett, Hrbek, etc. Yes, he did mash left handed hitting but he was good against righties also. https://www.twinkietown.com/2017/5/11/15626864/how-the-twins-lost-shane-mack
