I hadn't looked for awhile but we have the best team defense in all of baseball https://www.fangraphs.com/leaders.aspx?pos=all&stats=fld&lg=all&qual=0&type=1&season=2018&month=0&season1=2018&ind=0&team=0,ts&rost=0&age=0&filter=&players=0
Cain is leading all outfielders in defensive runs saved last I looked. He probably couldn't have robbed the hr because he couldn't jump high enough but I think he could have made the others.
