Early and personal life

Thiago Moura Monteiro was born on May 31, 1994, in Fortaleza, Ceará, Brazil. Thiago has three sisters (Letícia, Jéssica and Flávia) and an older brother, Fáber Monteiro, who works as a real estate broker. His mother Fátima Monteiro is retired since he was a child. Monteiro is fluent in Spanish, Portuguese and English.

Thiago's first introduction to tennis happened when he first saw his brother watching Gustavo Kuerten on TV, being eight years old. Monteiro trained football at an academy near where his brother used to play tennis. He played it for the first time when his football class was cancelled and his brother called him to ''hit the ball''. Thiago soon started training and disputing local tournaments: in early 2004 he won his first tournament, being only nine years old. Thiago would leave his hometown, Fortaleza, in late 2008 to enter the Larri Passos Academy in Balneário Camboriú to improve his game. Thiago says that if he had not made that change, he would probably be a football player. Now as a professional player, Thiago uses his spare time to enjoy movies and spend it with friends and family. He attends college online. He dated fellow Brazilian tennis player Beatriz Haddad Maia for several years.

Thiago Monteiro had a successful junior career, winning many tournaments. Monteiro peaked in the ITF Junior Circuit rankings at No. 2 on 2 February 2012. He ended his junior career with a 77–31 win record on singles and 47–32 on doubles.

In 2004, being 10 years old, Thiago won the Paraíba Tour Tournament. In 2005, Monteiro won the Fortaleza Cup, by beating Evandro Alencar in straight sets on the final and in 2006, he captured the first of three titles at the Banana Bowl, at the category u12. 2008 was a very successful year for Monteiro, both in singles and in doubles. He won the South-America Tournament of Nations, the Torneio Brasileirão, the Guanabara Open de Tênis (4th and 5th stage), all singles tournaments; and the 1st and 2nd stage of Torneio Nacional Rota-do-Sol (both in singles and doubles). Monteiro also conquered his second Banana Bowl title, category u14. Later that year, Thiago was awarded with Troféu Jornalista Flávio Ponte, at the category Personalidade Esportiva do Ano (''Sports Personality of the Year'').

To focus on his tennis career, Thiago moved from his hometown in Fortaleza, to Balneário Camboriú, in Santa Catarina. This change led Thiago to conquer multiple titles in 2009: Copa Claro (3rd stage) and Credicard MasterCard Junior Cup (2nd and 3rd stage), in singles tournaments, and the doubles titles at XIV Goodyear Junior Cup and the Eddie Herr Tennis Championship. Monteiro was also runner-up at the G1 tournament, Orange Bowl, playing in the singles draw. This same year, he won his first points on the ATP rankings by playing two Futures' events, in doubles category.

Starting 2010, Thiago was the number one in both CBT and COSAT ranking. He won his third and final title at the 40th edition of the Banana Bowl, this time at the u16 category and also made his debut on the ATP Singles Rankings, with his participations on a Future in his birthplace, in Fortaleza. In 2011, Thiago started the year winning the Grade A, Copa Gerdau in Porto Alegre, one of the most important tournaments on the ITF Junior Circuit. Being 17 years old, Monteiro also won three other clay tournaments: Asuncion Bowl, Astrid Bowl and the Offenbach Tournament.

Thiago didn't achieve much success in singles Grand Slams as a junior: his best results were reaching the third round at the Wimbledon Championships in 2011 and at the 2012 French Open. He had a better run at doubles: reaching the quarterfinals of the Australian Open and the semifinals at the French Open, both in 2012. Monteiro's last match as a junior was at the 2012 US Open.

In late 2011, Thiago won his first professional title, the Bahia Open, a Future tournament with US$10,000 in money prize. He battled past his training partner Alexandre Schnitman, winning in close, straight sets. This win led Thiago to receive a wildcard entry on the main draw of Aberto de São Paulo, but he was eliminated on first round by compatriot André Ghem.

2012 was the last junior year for Monteiro. He played in all junior's Grand Slams except Wimbledon, and also focused on Futures and Challengers tournaments. Monteiro managed to qualify at 2012 Aberto de Florianópolis, in late February, but he was eliminated in the first round by Thiago Alves. In late May, Thiago won his second Futures title, this time on clay, in Bauru. The final was a thrilling three-hour victory over Leonardo Kirche, with Monteiro winning despite losing the first set. The Brazilian was runner-up on two other Futures played in Brazil: at São José do Rio Preto in August and at Porto Alegre in October. Thiago ended the year with a career ranking of 439, after starting the year at the position 701.

Entering 2013 as the first year that Thiago would play a full season as a senior professional, he was invited a second time to enter Aberto de São Paulo main draw, but couldn't make the first round again, losing to countryman Guilherme Clezar in straight sets. Monteiro later played on consecutive Futures events in United States, without much success. He tried to break through the qualifiers of Brasil Open a month later, but lost to Thiago Alves in the first round.

He attempted to do so in clay events, reaching the final qualifying round in the Argentina Open and the U.S. Men's Clay Court Championships, losing respectively to Facundo Bagnis and Rogério Dutra Silva. While his run on qualifiers wasn't much successful on the ATP World Tour, Thiago had better success at the ATP Challenger Tour.

However, Rajeev Ram withdrew from the tournament, and Monteiro was awarded with a lucky loser entry into the main draw. Unfortunately for Thiago, he didn't have the same luck during the first round match, against Tim Smyczek. Monteiro had the opportunity to serve for the match at 5–4 during the second set, but Smyczek denied his chances and won the match in three sets. Thiago also did his debut in doubles in Atlanta, playing with Yoshihito Nishioka, but they lost at the super tiebreak against American partnership of Zack Kennedy and Christopher Eubanks.
