This study investigates how Fabrizio Romano uses writing style on X (formerly Twitter) to establish credibility and build his identity as a sports journalist. Although scholars have examined sports communication, branding, and influencer journalism, little research has explored how specific social media reporting styles affect reader comprehension and engagement. This study identifies Romano’s stylistic elements and examines how they shape readers’ understanding of, and interaction with, his content. A mixed-methods design combined qualitative stylistic analysis with quantitative audience data. The analysis was guided by Martin Joos’s (1967) Theory of Language Styles and Leech and Short’s (2007) stylistic framework, enabling classification of language styles and analysis of linguistic patterns. Fifty text-based posts from Romano’s verified X account, published between June and July 2025, were sampled for content analysis. A structured questionnaire was administered to 150 randomly selected followers to capture their reading preferences and usage patterns. Descriptive statistics and thematic analysis were used to interpret the data. Findings show that Romano predominantly uses consultative and casual styles to convey confirmed transfer information, reserving formal style for official announcements. These choices produce a dual effect, establishing credibility and authority while cultivating familiarity with readers. Survey responses indicate the styles positively influence perceived trustworthiness, clarity, and authenticity, driving high audience engagement. The researcher concludes that stylistic choices are central to how social media sports journalism functions, linking information presentation to audience response. Future research should test these findings across other platforms and media environments.
