American League manager Jim Leyland says you can count on that.
"Rest assured No. 42 will be on the mound at some point," Leyland said Monday at Citi Field.
Rivera has said he's going to retire at the end of the season.
There was some concern that Rivera may not get in because the American League is the away team, and he wouldn't be guaranteed to pitch the ninth inning if the National League is leading entering the frame.
Rivera, 43, is 30-of-32 in save opportunities and owns a 1.83 ERA this season.
Leyland said he would be picked to close if there is a save situation.
"I can assure you that will happen," Leyland said.
