Jim Leyland just wasn't about to take that chance.
Summoned in the eighth inning to make certain he would pitch, Rivera soaked up a 90-second standing ovation and got three straight outs while helping the American League to a 3-0 victory over the National League on Tuesday night at Citi Field.
"I think the plan was perfect," said Rivera, who took home the MVP trophy.
Rivera reported early for work and the New York Yankees' indomitable closer combined with nine other pitchers on a three-hitter as the AL snapped a three-game skid and regained home-field advantage in the World Series.
Leyland, the AL manager, had promised Rivera would pitch. So rather than risk waiting for a save opportunity that might never come, the Detroit Tigers' skipper made his much-awaited call one inning earlier than Rivera is accustomed, just in case of "something freaky."
"If anybody ever messed up Mariano Rivera, I can lay claim to that," Leyland said. "I just couldn't take any chance. You know, I'm probably not the most popular manager in baseball. I wanted to make sure I got out of here alive."
Robinson Cano hobbled off early after getting hit by a pitch from crosstown rival Matt Harvey of the host Mets.
Harvey and opposing starter Max Scherzer were among a record 39 first-time All-Stars in a game that featured four precocious players 21 or younger—baseball's next generation.
Both came out throwing 99 mph heat, but it was Rivera, at 43 the oldest All-Star since Carlton Fisk in 1991, who was the center of attention in his farewell season.
Baseball's career saves leader came in from the bullpen to Metallica's "Enter Sandman," just like across town at Yankee Stadium, and was left alone on the field to take in a stirring ovation.
"It was a great moment. He is one of the best pitchers that's ever played this game," Tigers outfielder Torii Hunter said.
All-Stars on both sides clapped from the top of the dugout steps, and Rivera tipped his cap to the crowd.
Then he went to work, retiring three straight hitters on 16 pitches—all cutters, as usual—before walking off to another ovation and receiving a hug from Detroit ace Justin Verlander.
"It was tough. It was special," an emotional Rivera said. "Seeing the fans sharing and both teams standing out of the dugout, managers, coaches, players—priceless."
Next stop, the Hall of Fame.
The game's greatest reliever, quiet and humble by nature, addressed his AL teammates before they took the field. He made it quick, just like his outing. Most of them, actually.
"What I said was that I was honored and it was a privilege for me to play with all of them for so many years," Rivera said.
The lengthy cheers provided a fitting tribute and the latest salute to Rivera, set to retire after this season. The 13-time All-Star is on something of a farewell tour, receiving creative gifts at each opposing ballpark he visits for the final time.
He got a rocking chair built out of broken bats in Minnesota, a decorated surfboard and bottle of wine in Oakland.
The last time he was at Citi Field, though, things didn't go so well. He was honored by the Mets before a game in late May, threw out a ceremonial first ball—and then had his first blown save of the year.
While other All-Stars wore flashy spikes, Rivera stayed with traditional black. No surprise for Mr. Steady.
Rivera has never allowed an earned run in nine All-Star innings. The only older pitcher to appear in an All-Star game was 47-year-old Satchel Paige 60 years ago, according to STATS.
"First class all the way," Mets captain David Wright said. "Well deserving for Mariano.
Winning pitcher Chris Sale from the Chicago White Sox worked two perfect innings for the AL, which posted its third shutout and first since 1990 at Wrigley Field to trim the NL lead to 43-39-2 in All-Star games.
The National League didn't manage a baserunner until Carlos Beltran's one-out single in the fourth.
It was the ninth All-Star game in New York—most for any city—and second in five years after a farewell to old Yankee Stadium in 2008. But the only other time the Mets hosted was during Shea Stadium's debut season in 1964, when Philadelphia Phillies outfielder Johnny Callison hit a game-ending homer in the ninth.
This one gave the struggling Mets a chance to pack their cozy ballpark for one of the few times all season. Fans chanted Harvey's name during pregame introductions, and the 24-year-old sensation delivered with three strikeouts in two shutout innings.
He walked off to a standing ovation and received a pat on the back from NL manager Bruce Bochy of the San Francisco Giants, the defending World Series champions.
Harvey was the youngest All-Star starting pitcher since former Mets ace Dwight Gooden was 23 a quarter-century ago—and the first from the home team since Houston's Roger Clemens in 2004. Gooden cheered Harvey on from the stands.
All the buildup might have made the phenom a little too excited at the start. Mike Trout doubled inside first base on his opening pitch, and Harvey drilled Cano just above the right knee with a 96 mph fastball on the third.
In obvious pain, Cano initially stayed in the game but limped off after Triple Crown winner Miguel Cabrera struck out—just as he did against Harvey in spring training.
Cano crossed in front of the mound while heading to the dugout, and Harvey patted himself on the chest.
"I didn't mean to, obviously," Harvey said. "I feel terrible. Apologies go out to him."
Cano has a bruised quadriceps but said he'll be ready to play when the Yankees come out of the All-Star break.
"Just a little tight," Cano said. "I'll be good for Friday."
Wright went to the mound for a calming chat with Harvey, who whiffed Jose Bautista to end the inning.
Cano's name came up all night—even after he left the game. A fan in a Cano shirt ran on the field and gave himself up to security near second base as players backed away a bit, but was tackled anyway to the delight of the crowd.
Cabrera's bat slipped out of his hands on a swing and sailed 10-15 rows deep, where it nearly clipped another fan in a Cano jersey.
Cabrera's next cut against loser Patrick Corbin produced a leadoff double in the fourth, and Bautista's sacrifice fly snapped a 17-inning scoreless streak for the AL that dated to Adrian Gonzalez's homer off Cliff Lee two years ago in Arizona.
Baltimore's Adam Jones, wearing bright orange high-tops, doubled against Lee to start the fifth and scored while J.J. Hardy beat out a potential double play. Kipnis doubled home a run in the eighth off Atlanta closer Craig Kimbrel.
