Betts was named Monday as Trout's replacement by virtue of receiving the most player votes among non-starters in the outfield, Major League Baseball confirmed. The Boston Red Sox right fielder actually finished second in player voting among AL outfielders behind only New York Yankees sensation Aaron Judge.
Betts, who had been selected to the AL team as a reserve, was also named AL Player of the Week. He punctuated the week with eight RBIs Sunday against the Toronto Blue Jays.
Entering play Monday night in Texas, Betts was batting .286 with an .874 OPS. He was leading the league with 27 doubles and the Red Sox with 15 homers and 51 RBIs.
"He gets on these hot streaks where seemingly there's a lot of damage to the swing," Red Sox manager John Farrell said. "The one thing that has always stood out about Mookie's approach to the game is not only a genuine humility, but an aptitude that is second to none. He is not afraid to expose himself in terms of not knowing everything and will ask great questions. But the aptitude to apply it quickly, that's what sets him apart."
