 Biographical information
Giuseppe Mazzanti has played for the Italian national team in several events, including the 2004 Olympics. After a year in the minor leagues, he has played in Italy, having a big year in 2007. His cousin Leonardo Mazzanti has also played for the Italian national team.
Mazzanti debuted in Serie A1 in 1999 with Caffe Danesi Nettuno, hitting .313/.353/.313 in 7 games. He would not play again in Serie A1 for five years. In 2001, he was on the Junior European Championship team for Italy.
Mazzanti signed with the Seattle Mariners and was a corner infielder for the 2002 AZL Mariners, hitting .203/.284/.331. His three homers tied for third on the club but he struck out in 40 of 116 AB. The infielder was 0 for 3 with two strikeouts for the Italian team in the 2003 Baseball World Cup, his debut with the senior national team. He also made two errors in three chances at third base while backing up Igor Schiavetti.
Mazzanti batted .257/.364/.429 with 34 runs and 37 RBI in 2004 for Caffe Danesi Nettuno, back in Serie A1. The 21-year-old hit .313/.316/.375 as Italy's main third baseman in the 2004 Olympics and was error-free. He led the team's starting position players in average.
Mazzanti produced at a .387/.483/.547 clip in just 22 games in Serie A1 in 2005. In 2006, he slipped to .244/.333/.360 in 48 contests. That year, he was with Italy for the 2006 Intercontinental Cup, he batted .273/.429/.424 and tied for the team lead with 9 RBI. He again struggled defensively, with a .810 fielding percentage at the hot corner. He played a couple games at first, flipping positions with Alex Liddi, who had followed Mazzanti to the Mariners farm system. Mazzanti tied for 4th in the Cup in RBI, even with Frederich Cepeda, Yung-Chi Chen, Ivanon Coffie, Gino Lollio and Ariel Pestano.
Mazzanti became a star in Serie A1 in 2007. He hit .345/.472/.592 for Nettuno. He was second to Maximiliano De Biase in average, led in OBP, led in slugging, led in OPS by 87 points over the runner-up, led in doubles (18) and tied for 5th in home runs (5). Mazzanti was honored as the top Italian hitter by claiming the Max Ott Award for 2007. In voting at www.baseball.it, he won the nod as the All-Star third baseman as well. He kept it up in the 2007 European Championship, hitting .522/.593/.696 and leading the Italian team in average, OBP and slugging and tying Laidel Chapellí for the most runs (7). He again played first when Liddi was at third and third base when Liddi manned first.
Mazzanti remained with Italy for the 2007 Baseball World Cup and batted .095/.174/.143 as one of two Italian starters to perform very poorly; Chapellí was his rival for the team's big disappointment at the plate.
Mazzanti was the top hitter in the 2008 European Cup in Regensburg, batting .500/.636/1.214 for second-place Nettuno. He had 7 runs, 7 RBI, 7 walks, 4 doubles and 2 home runs in five games. He was the key performer in their upset over DOOR Neptunus in the semifinals, with a double, homer, two runs and two RBI. He tied Raily Legito for the Cup lead in doubles, tied four others for the lead in home runs, was one RBI behind leader Eugene Kingsale and tied for the most total bases (17). He was only 1 for 7 in the 2008 European Cup Final Four that fall but Nettuno won the title.
In the 2008 Italian Baseball League, Mazzanti hit .392/.516/.574. He led the league in average (.012 ahead of Willie Vasquez), OBP (.010 over Claudio Liverziani) and was third in slugging. He won MVP honors. The next native Italian to win would be Alessandro Vaglio in 2013.
He hit .389/.500/.389 in the 2009 European Cup's Nettuno phase with 6 runs in five games. In the Cup's Final Four, he was two for four with five walks, a double, a homer, 2 runs and 4 RBI. His 3-run homer off Michiel van Kampen powered Nettuno to a 6-4 win over Kinheim; in the finale, he had the game's lone run, drawing a walk from Yulman Ribeiro, taking two bases on a botched pickoff throw from Matt Stocco, then coming home on a Manuel Gasparri single. He led the Final Four in runs, RBI, total bases, walks and homers (tied with Danny Rombley).
