Biographical Information

Oscar Nakaoshi pitched for the Brazilian national team in the 2008 Americas Baseball Cup at age 17; he was 0-1 with a 2.08 ERA, allowing 6 hits and 3 runs (one earned) in 4 1/3 IP while fanning four. He started and took the loss against Venezuela after pitching scoreless relief in his first two outings. The left-hander set his college's record in wins (28), following fellow Brazilians Rafael Fernándes and Hugo Kanabushi to Hakuoh University in Japan. He pitched for Honda in the industrial leagues after college.

He then was on Brazil's roster for the 2013 World Baseball Classic Qualifiers. He started against Colombia and shut them out for four innings on five hits, two walks and four strikeouts against a lineup with four future, past or present major leaguers before Carlos Yoshimura relieved; Brazil won with Yoshimura getting the decision. Brazil would win a spot in the 2013 World Baseball Classic. In the Classic, he relieved Murilo Gouvea with a surprising 3-2 lead over defending champion Japan in the top of the 7th. He struck out Nobuhiro Matsuda and Hayato Sakamoto then got Kazuo Matsui on a grounder. In the 8th, though, he ran into trouble. Seiichi Uchikawa singled, Yoshio Itoi bunted him over and Hirokazu Ibata singled to tie it. Kesley Kondo relieved and let the inherited runner score, tagging Nakaoshi with the loss. He then got the start and did very well versus China (4 IP, 4 H, 0 R, 0 BB, 6 K) before Gouvea relieved and took a 5-2 loss when fading in the 8th.

Nakaoshi was picked by the Hiroshima Carp in the 6th round of the 2015 NPB draft. He was 2-0 with a 6.35 ERA for Hiroshima in 2016, also appearing 17 games on the farm (1-1, 2 Sv, 4.50). In 2017, he allowed one run in 1 2/3 IP for the top club and was 1-4 with six saves and a 3.05 ERA in ni-gun. He was 6th in the minor Western League in saves. In 2018, he had a 2-1, 3.94 record on the farm and did not pitch for the big club, ending his run in NPB. He then returned to the Japanese industrial leagues.

He was on Brazil's announced roster for the 2020 World Baseball Classic Qualifiers before those were canceled due to the COVID-19 pandemic. He pitched three times for Brazil in the 2022 World Baseball Classic Qualifiers, tying Nicaragua's Carlos Téller for the most appearances in the event. His first outing came against New Zealand when he relieved Heitor Tokar in the 7th with a 6-3 lead. He went 1-2-3 against Andrew Marck, Beau Bishop and Daniel Lamb-Hunt, striking out the first and third of those. Igor Kimura relieved him. His next outing, he replaced Felipe Sales in the 5th with one on, one out and a 3-1 lead over Nicaragua. He got Melvin Novoa on a double play grounder to end that inning. In the 6th, he retired Steven Leytón, Benjamín Alegría and Elmer Reyes in order. He opened the 7th by striking out Cheslor Cuthbert, then Luis Montealto grounded out. Sandy Bermudez became the first player to reach against him with a single then Dwight Britton hit into a force. Igor Januário took over for him in the 8th, Nakaoshi putting in a solid hold. Hid last game also was against Nicaragua, with a spot in the 2023 World Baseball Classic at stake. He relieved Gabriel Barbosa with two outs in the 6th and a 2-1 deficit and got Isaac Benard on a pop-up. In the 7th, Montealto doubled and Leytón walked. Alegría bunted them over and Reyes hit into a run-scoring force, followed by Britton also hitting into a force. When Novoa opened the 8th with a double, he was relieved by Enzo Sawayama, who escaped the jam. Only Sawayama finished with a better ERA for Brazil in the event and only Barbosa worked more innings.
