Italy 8, United States 6. That’s the World Baseball Classic score that has baseball fans doing double takes after an upset at Daikin Park in Houston. The pitcher who shut down the American lineup? Michael Lorenzen, a 34-year-old right-hander who plays for the Colorado Rockies and grew up in Anaheim, California. He took the mound wearing an Italian jersey.

The WBC allows players to compete for countries where their heritage or ancestry makes them eligible for citizenship. That rule put Lorenzen — born, raised, and currently employed by an American MLB franchise — in Italy’s uniform. And he made the most of it.

How Lorenzen Dominated His Own Country’s Hitters

Lorenzen started the game for Italy and pitched 4⅔ scoreless innings, allowing two hits and one walk before exiting with Italy leading 5–0. Italy’s offense later pushed the margin to 8–0. The United States mounted a late rally with six runs, but Italy held on to win 8–6.

“It’s kind of weird throwing against your own country,” Lorenzen said, per ESPN.. “But it was an incredible night.”

His postgame comments revealed a focused game plan against the U.S. hitters:

“Obviously, they’re really good hitters. They’re not going to stretch the zone a ton. So you got to trust your stuff. Be in the zone, mix and match. Have a good have a good plan, and yeah, we were just able to be efficient. Kind of get early out, some ground ball outs and just keep it rolling.”

A Scheduling Quirk That Shaped the Upset

The matchup almost didn’t happen this way. Lorenzen only ended up facing the U.S. because the Colorado Rockies didn’t want to disrupt their rotation plans for the regular season by having him throw a day later against Mexico. A scheduling preference by his MLB club created one of the tournament’s biggest upsets.

That kind of behind-the-scenes roster management rarely makes headlines. But it shaped the outcome of a game with direct elimination implications. After Italy’s victory, the result of a later WBC game between Italy and the Mexico national baseball team could affect whether the United States advances or faces possible elimination from the tournament.

That’s a striking position for a team loaded with MLB talent.

Lorenzen’s MLB Career

Lorenzen is no journeyman scrub. He was drafted 38th overall by the Cincinnati Reds in 2013, selected in the first round. Over his Major League career, he has made 119 starts and earned one All-Star selection.

His path to the big leagues started at Cal State Fullerton, where he was both a pitcher and an outfielder for the Titans. He made his MLB debut with the Reds in 2015, then signed with the Los Angeles Angels for the 2022 season and the Detroit Tigers before the 2023 campaign. That 2023 season was his best: he was named an MLB All-Star.

His MLB journey has taken him through seven organizations — the Cincinnati Reds, Los Angeles Angels, Detroit Tigers, Philadelphia Phillies, Texas Rangers, Kansas City Royals, and now the Colorado Rockies. He signed a one-year contract worth $8 million with Colorado in January 2026.

The Backstory Behind the Pitcher

Lorenzen grew up in Anaheim with three older brothers: Jonathan, Matthew, and Anthony. Baseball ran through the family. Jonathan played two seasons in the Los Angeles Dodgers organization, and Matthew played college baseball at Cypress and Fullerton Colleges.

Lorenzen is married to Cassi Lorenzen, who graduated from San Diego State University with a nursing degree and previously played volleyball at Foothill High School. The couple married in November 2016 at Rancho Bernardo Inn in San Diego. They welcomed their first child, June Elizabeth, in November 2022 and a baby boy born in January 2025.

The WBC Eligibility Rule, Explained

The WBC’s heritage-based eligibility rule allows players to represent countries where their ancestry qualifies them for citizenship, even if they were born, raised, and play professionally elsewhere. The structure has existed since the tournament’s inception, but most people only pay attention when it produces a result like this one.

An 8–6 upset of the United States, fueled by 4⅔ scoreless innings from a pitcher who calls Colorado his current MLB home, is the kind of outcome that makes people look up the rules.
