That second hole is the LA Angels superstar to pair with Mike Trout at the top of their lineup. Throughout his career, Trout has been alone as an elite hitter in the top half of the Halo lineup. Anthony Rendon changes that as he naturally slots below Trout, giving him protection.
But the Rendon acquisition does raise an interesting question: Is Anthony Rendon the most talented teammate Mike Trout has ever had?
In short, yes.
In terms of the best player to ever play alongside Mike Trout, that honor obviously goes to Albert Pujols.
