Sixto Sanchez is officially in the game for Miami…

The 22-year-old Dominican professional baseball pitcher threw his first pitch for the Miami Marlins in the first spring training game of his career, squarely meeting Jose Altuve‘s bat.

The Houston Astros star grounded a leadoff single on Monday, but Sanchez shook off the setback on his way to 1 2/3 scoreless innings in West Palm Beach, Florida.

The season debut by the highly regarded right-hander was delayed by a visa issue and then a false positive on a COVID-19 test.

“I don’t feel frustrated, but it was a weird feeling,” Sanchez said via a translator. “That false positive spoiled my momentum, but I’m not that far behind. I just can’t pitch as many innings as the other guys.”

Because of off days, the Marlins could skip Sanchez’s first two turns of the season. But he’s expected to join the rotation by mid-April and is widely projected as a future ace.

“We know what we have with Sixto,” manager Don Mattingly said. “It’s just a matter of getting the process started for him. … It looked like his stuff was good. He was throwing strikes for the most part.”

Sanchez, acquired in the trade two years ago that sent catcher J.T. Realmuto to the Philadelphia Phillies, made his MLB debut last August. He went 3-2 with a 3.46 ERA in seven starts and pitched five shutout innings against the Chicago Cubs in the playoffs.

Against the Astros, Sanchez threw 30 pitches and topped out at 100 mph, which didn’t faze Altuve.

“He was ready, waiting for that fastball,” Sanchez said. “They’re going to be ready for that heat.”

As an alternative, Sanchez has been trying to polish his changeup this spring. He’ll get a chance to do so again Saturday, when he is tentatively scheduled to pitch three innings in his next start.
