On Saturday, Major League Baseball announced Alvarez has been added to the National League All-Star squad, replacing Washington's Jordan Zimmermann, who will not be attending due to right biceps cramps.
In his fourth big league season, Alvarez (6-4) will be attending his first All-Star Game. He gives Miami two representatives on the NL squad. Giancarlo Stanton was selected as a reserve outfielder, and the slugger is expected to be the designated hitter.
"We talked about a guy stepping up and stepping in [for Fernandez], and Henderson definitely has done that," Marlins manager Mike Redmond said. "Last year, everybody talked about Jose, and rightfully so. He was amazing. But it's great to see guys step up and get recognized for their work. It's been fun to watch Henderson develop."
The Marlins had won a franchise-record 10 straight Alvarez starts. But that streak ended on Friday with a 7-1 loss to the Mets at Citi Field. Alvarez had a string of nine straight starts of allowing two earned runs or fewer snapped.
The right-hander from Venezuela achieved a piece of MLB history last year when he no-hit the Tigers in the regular-season finale.
"When you think back to last year when he threw the no-hitter, I think that's kind of been a catapult for him, and led to the success he's had this year," Redmond said.
A strike-thrower who relies on movement of his pitches, Alvarez is a terrific athlete. He is a plus fielder, and he handles the bat well.
"He's definitely been the anchor, holding [the rotation] down," Stanton said. "This is good for him."
The Marlins acquired Alvarez from the Blue Jays as part of a blockbuster 12-player deal.
Alvarez will be available to pitch in Tuesday's Midsummer Classic in Minnesota if his number is called.
With Alvarez heading to the All-Star Game, the Marlins are rethinking how they will set their rotation after the break. Alvarez, even if he doesn't pitch Tuesday, likely wouldn't get the start for Miami on Friday against San Francisco at Marlins Park. Nathan Eovaldi is the likely choice to start off the second half.
At the All-Star Game, Alvarez is eager to be around fellow Venezuela native Felix Hernandez of the Mariners, as well as Clayton Kershaw of the Dodgers.
"There's a lot of guys I'd like to see," Alvarez said. "Everybody is an All-Star. I especially look forward to seeing pitchers from the American League. Felix Hernandez is a pitcher I've admired when I was coming up and watching him pitch."
Alvarez sports a bright orange glove, and he's known for being quirky. Before throwing his first pitch, Alvarez will do an elongated windup, extending forward before tilting back and into his full delivery. He only does it for the first pitch.
"That's my routine," Alvarez said. "I've always had it in the big leagues with the first pitch of my delivery."
Alvarez's fastball typically is in the 93-96 mph range, and he mixes in breaking balls. He even has a super-slow curveball that floats up there in the 58-mph range.
Redmond calls that pitch, "The Henderson." Others have referred to it as an Eephus pitch. Either way, it typically results in takes by hitters or overly aggressive swings.
"Henderson has been one of our workhorses," catcher Jarrod Saltalamacchia said. "He's been able to give our bullpen a rest, and [he] picked us up when we needed a big win. He's just been a great leader of our staff since Jose has gone down."
