On 7 June, Ogasawara would be robbed once again of his maiden win this time against the Orix Buffaloes as Shinji Tajima gave up a run in the 9th inning to even the scores. Reliever Toshiya Okada would take the win after the game went to extra innings.

On 20 August, against the Baystars, he pitched a season high 7 innings but was unable to claim his first win of the season after giving up Yoshitomo Tsutsugoh's 36th home run of the season in his first inning.

## Personal

"Shinnosuke" is a name inherited from his grandfather.
He shares the same hometown as team-mate Shuhei Takahashi and the two attended the same elementary school and played at the same junior baseball side Shonan Boys. They played together in a local park as boys and their homes are said to be separated by about 10 minutes walk. When Shuhei turned professional with the Dragons, it was the then middle-school student Ogasawara that presented him with a celebratory bouquet.
He has remarked on his admiration for Masahiro Yamamoto formerly of the Dragons and Hiroki Kokubo former Fukuoka SoftBank Hawks infielder and then manager of the Japan national baseball team. Ogasawara also has great respect for former New York Mets and San Francisco Giants outfielder Tsuyoshi Shinjo hoping to emulate his success.
He is also a fan of pro wrestling and the WWE. Ogasawara admires Japanese wrestler, Tatsumi Fujinami.
Ogasawara also enjoys the Japanese idol girl group SKE48 and supports Jurina Matsui. He has been cheering her on since elementary school and knew of her since her featuring on AKB48's 2008 single Ōgoe Diamond. He mentions that "I thought she was really young and really gave her all."　On 5 May 2017, when Ogasawara was with the first team, it was Matsui who performed the first pitch ceremony where the SKE48 performer admitted to following Ogasawara on Twitter and knowing of his fondness for pro-wrestling.
