Italy

Italy debuted its national team at the inaugural European Baseball Championship in 1954, which it won. Since then, the team has won nine gold medals at the tournament, with their most recent being in 2012. In total, Italy has won 27 medals (16 silver, 3 bronze). The only country to have fared better is the Netherlands (21 gold, 7 silver). Italy served as the host nation for the 1956, 1964, 1971, 1979, 1983, 1991, and 1999 games.

In the 2006 Intercontinental Cup, held in Taichung, Taiwan from November 9 to 9, Italy finished sixth. They secured an impressive 13–3 victory over Chinese Taipei in their first game of the tournament, however, they lost their next three match-ups to Netherlands, Cuba, and Australia (13 innings). After coming back with a victory against the Philippines, Italy lost their next two to Japan and South Korea to end the round robin first phase of the tournament with a 2–5 record. Italy came back to beat South Korea in the first game of the following round, 8–3. In the battle for fifth place, Italy lost to Australia, 3–2.

On November 9, 2007, Italy handed the U.S.A. team their only loss in Team U.S.A.'s route to win the 2007 Baseball World Cup in Taiwan. It was the U.S.'s first loss to Italy in 21 years and the first time it ever lost to Italy with professional players, as the team consisted of Major League Baseball players and top minor league prospects. Both Italy and Panama ended up with 3–4 records in the 2007 games; however, Panama's 5.85 run ratio versus Italy's 4.73 placed them in fifth place while Italy settled for sixth.

The 2009 Baseball World Cup took place from September 9–27. Seven European countries, including Italy, hosted and participated in the tournament of 22 teams. The event was made up of five groups consisting of four teams each, for a total of 20 teams. Italy (Bollate, Bologna, Codogno, Florence, Godo, Macerata, Parma, Piacenza, Reggio Emilia, Rimini, San Marino, Torino, Trieste, Verona, and Vicenza) and Netherlands (Rotterdam, Haarlem and Amsterdam) serve as hosts of the 16 teams of the second round (September 14–20), and therefore received first round byes. The group Italy hosted in the second round included Australia, Canada, Taiwan, Japan, Mexico, Netherlands Antilles and the U.S.A..

Italy lost two more to Canada and the U.S.A. before winning their final game against Netherlands Antilles. Italy finished the second round with a 2–5 record, and were eliminated.

At the 2010 Intercontinental Cup, Italy gained the first medal in the history of the tournament, beating Chinese Taipei 4–3 in the bronze medal game,.

At the inaugural World Baseball Classic in 2006, a new international tournament organized by Major League Baseball with IBAF sanction, Italy competed in Pool D. The pool, which included Venezuela, the Dominican Republic and Australia, was played in Lake Buena Vista, Florida, at The Ballpark at Disney's Wide World of Sports. Italy secured an impressive 10–0 win over Australia in its first game, invoking the mercy rule after seven innings. However, they dropped their next two games to Venezuela, 6–0, and the Dominican Republic, 8–3, and failed to qualify for the second round of the tournament.

With only ten players on their roster with any major league affiliation, Italy was a heavy underdog in Pool C of the 2009 World Baseball Classic. With Canada, the U.S.A. & Venezuela completing Pool C, it was arguably the toughest pool in the WBC. Prior to the start of the WBC, Italy played two spring training games against the Washington Nationals and New York Mets. Italy trailed through most of the game against the Nationals until Chris Denorfia and Michael Costanzo drove in a run apiece in the seventh inning, and an eighth-inning two-run home run by Valentino Pascucci tied the game at six. A ninth-inning walk-off three-run home run by Roger Bernadina capped off a late rally in the Nats' 9–6 victory over Italy. Against the Mets, Italy led 2–0 going into the ninth inning. Cory Sullivan hit a two-run home run to tie the game at two, and Jeremy Reed doubled in Daniel Murphy to give the Mets a 3–2 victory.

Italy was again shut out by Venezuela in their first 2009 WBC game, 7–0 on March 7. Starter Mark DiFelice held Venezuela scoreless through the first four innings; however, Venezuela immediately took advantage of Italy's less experienced bullpen, exploding for 4 runs in the fifth. Against Canada on March 9, Italy pulled off one of the more surprising upsets in the 2009 WBC, winning 6–2, and eliminating the heavily favored Canadian team. Italy led 3–0 heading into the fourth inning, until Canada jumped on starter Dan Serafini for two runs. With the bases loaded and only one out, reliever Chris Cooper struck out Peter Orr, then got Chris Barnwell to fly out to center to end the threat, and keep Italy in the lead. In all, Italy's bullpen pitched six innings without giving up a run. With this victory, Italy faced their nemeses, Venezuela, a second time. After three scoreless innings pitched by Italian starter Adam Ottavino, Venezuela again dominated Italy's bullpen, scoring four runs in the fourth, and five in the fifth to win 10–1, and eliminate Italy from the World Baseball Classic.

Again considered a heavy underdog at the 2013 World Baseball Classic, Italy won its first two games in Pool D, 6–5 with a 9th-inning comeback over Mexico and 14–4 over Canada in a game called in the 8th inning due to the mercy rule. They lost both games in Round 2 against the Dominican Republic and Puerto Rico, thus eliminating them from the tournament.

Mike Piazza was named the manager of the national team in 2019, replacing Gilberto Gerali, who resigned when Italy failed to qualify for the 2020 Tokyo Olympics. Piazza, a member of the National Baseball Hall of Fame, had previously played for Italy at the 2006 Classic, and served as the team's hitting coach at the 2009 and 2013 WBCs. As part of his contract, he exercises control over all of the national federation's youth development system. His debut as Italy's manager was planned for the 2021 World Baseball Classic, but it was delayed due to the COVID-19 pandemic.

At the 2021 European Baseball Championship held in Piedmont, the Azzurri defeated Spain to earn the bronze medal, after having lost to Israel in the semifinals. Piazza, who left partway through the tournament for his father's funeral, was replaced on the bench by Doriano Bindi.

Piazza has come under criticism for relying extensively on Italian Americans and other players from the Italian diaspora, particularly in the World Baseball Classic. However, Piazza has defended the practice, telling Italian media in 2024 that "sometimes you have to take a step back to move forward." He added that "my dream is to develop a native Italian in every position. Then we can have a player with dual citizenship here and there, but mainly a squadra tricolore. That is the goal."
