Rafael Mentzingen

After the Ignite folded, Mentzingen joined USL Championship club Memphis 901 on 15 January 2020.

Born in Rio de Janeiro, Mentzingen came to the United States to play collegiate soccer at Bryan College. He spent two years with the Lions before transferring and playing his final two years of eligibility at Valparaiso. Mentzingen was selected in the fourth round of the 2019 MLS SuperDraft, but instead signed for USL League One club Lansing Ignite, with who he made his professional debut in 2019. The club folded after just one year of existence, with Mentzingen moving on to join Memphis 901 for the 2020 season.

Although he had already signed a contract with Lansing Ignite, Mentzingen was drafted 90th overall in the 2019 MLS SuperDraft by Columbus Crew SC, who retained his Major League Soccer rights through the end of the 2020 season. He had previously trained with the club in 2018, but he and the Crew determined that he "needed more experience at the professional level" before joining Columbus. The sides agreed that Mentzingen would sign with Lansing for the 2019 USL League One season and join the Crew for preseason in 2020 to battle for a roster spot.

Mentzingen moved across the state of Michigan in 2018, joining fellow National Premier Soccer League club Detroit City for the summer season. After appearing for the club in preseason, he made his competitive debut for Le Rouge in the first round of the 2018 U.S. Open Cup, starting and playing 113 minutes as Detroit knocked out Michigan Bucks on penalties. Mentzingen scored his first goals for the club on 27 May, bagging two goals and providing an assist after entering as a second-half substitute in an 11–0 victory over F.C. Indiana. He added another goal five days later, this time helping Detroit defeat F.C. Indiana by a scoreline of 8–0. Mentzingen played sporadically throughout the remainder of the season, finishing with three goals in eight total appearances as Detroit City failed to qualify for the playoffs for the third time in five seasons.

On 14 December 2018, Mentzingen signed for USL League One expansion club Lansing Ignite. He became the third signing in club history, inking a one-year contract pending league and federation approval. Mentzingen made his club and professional debut on 30 March 2019, entering as a second-half substitute against Richmond Kickers. His first professional goal came less than two months later, on 18 May in a home fixture against North Texas SC. The 54th-minute strike helped the Ignite earn a 2–2 draw against the eventual league champions. In July, Mentzingen would be named as the League One Player of the Month as the Ignite went unbeaten in six matches during the month. He scored two goals and provided three assists, including a stoppage time tally as part of a 3–2 victory over Forward Madison on 9 July. Mentzingen finished the season with six goals and a team-high seven assists from 24 appearances in all competitions; he was one of three Ignite players named to the League One All-League Second Team for their efforts. Nine days after Lansing was eliminated from the playoffs, the club folded due to financial difficulties; Mentzingen, along with the rest of the squad, was released from his contract and became a free agent.

Mentzingen made his Valparaiso and NCAA debut on 25 August 2017, as the Crusaders fell 2–1 against Northwestern. He scored his first Crusader goal a week later, helping Valpo defeat nationally ranked Loyola in the program's Missouri Valley Conference (MVC) debut. Mentzingen earned national recognition for a goal he scored in the 2017 Missouri Valley Conference Men's Soccer Tournament, although his "mesmerizing goal" came in a 4–2 defeat to Drake. He was named to the All-Missouri Valley First Team after tallying nine goals in 18 appearances on the season. As a senior, Mentzingen's scoring output fell off for the first time in his collegiate career: he tallied just two goals in 16 matches. Those goals came in a three-match span midway through the season, including his final collegiate goal in a 4–1 defeat to Oral Roberts on 1 October. He finished his Crusader career with 11 goals in 34 appearances and earned a second consecutive nod to the All-MVC First Team.

For the summer of 2017, Mentzingen moved to the National Premier Soccer League and signed for Lansing United. He debuted for the club on 14 May, playing 74 minutes and scoring a goal in a 2–0 victory over Milwaukee Torrent. Mentzingen continued his goal-scoring form through the first half of the season, tallying two goals against F.C. Indiana on 19 May and again versus AFC Ann Arbor on 26 May. After scoring a brace in a 4–2 win over Grand Rapids FC on 10 June, he was named as the NPSL national player of the week. His season was ended in late June due to injury, but Mentzingen finished the year with nine goals in nine matches and was honored as the Lansing United player of the year.

Mentzingen came to the United States in 2015 to play college soccer, joining the team at NAIA school Bryan College. He made his collegiate debut on 26 August, scoring in a 9–0 victory over Hiwassee. After scoring four goals in a two-match stretch in mid-October, Mentzingen was named as the Appalachian Athletic Conference Offensive Player of the Week. He finished the season with 11 goals in 17 appearances, was named as the AAC Freshman of the Year, and was placed on the All-AAC First Team. He continued to star as a sophomore, tallying three goals in the first two games of the 2016 season – the second of which was a bicycle kick in a 3–0 victory over Cumberlands. He earned his second career AAC Offensive Player of the Week nod at the end of October, capping a week where he scored four goals in two games against Montreat and Tennessee Wesleyan. Mentzingen finished the season with 11 goals in 18 appearances; he earned a second-consecutive All-AAC First Team nod, was on the AAC All-Tournament Team, and was named as an NAIA Second-Team All-American. He announced his transfer to Valparaiso following the season, finishing his two years at Bryan with 22 goals in 35 appearances.
