CINCINNATI — Aroldis Chapman’s first pitch zoomed in at 99 mph. The Reds closer was just warming up.

The Cuban lefty hit triple digits to all three batters he faced on Tuesday night, a scintillating ninth-inning performance in the All-Star Game that left the home fans wondering how much longer they’re going to see this up close.

Chapman finished off the NL’s 15-strikeout performance, which wasn’t enough for a win. The American League took advantage of several mistake pitches in a 6-3 victory, its third straight in the All-Star Game.

For Chapman, it was bittersweet. The hardest-throwing pitcher in the majors may be topping 100 mph in some other city before the month is over. The out-of-contention Reds are entertaining offers for their closer and starter Johnny Cueto, who is in the final year of his contract and wants more than the club is willing to offer.

“It is something that is part of the game but out of my control,” Chapman said, with trainer Tomas Vera translating. “I won’t worry about it. It is up to the front office what happens.”

Chapman put the final touches on an all-or-nothing performance by the NL pitching staff. The pitchers were two shy of the All-Star record for strikeouts, but also missed enough times to help the AL pull away.

Jacob deGrom fanned the side in the top of the sixth inning on only 10 pitches. He became the first pitcher in All-Star history to strike out the side with so few pitches.

“I was pretty nervous in the bullpen but when I got on the mound, it went away,” he said. “I was just letting it go. I knew I only had one inning.”

Reds fans had hoped to see Chapman come out of the center field bullpen and blow away the AL to close out a win. Instead, NL manager Bruce Bochy decided to let him pitch the ninth even though the NL trailed 6-2 at the time.

After starting off with that 99 mph fastball, the lefty threw the next one at 101. That started a streak of nine straight pitches hitting at least 100 mph, with two of them topping out at 103. He fanned Brock Holt, Mike Moustakas and Mark Teixeira while players on the AL bench shook their heads and marveled.
