Regrettably, yesterday's result was as you can see.

Literal

Regrettably, yesterday [topic-は] [honorific-ご]view [as-per-の通りの] result [into-と] became.

A post-event polite acknowledgment of a bad outcome. ご覧の通り ('as you see,' 'as is visible') is a keigo expression: ご覧 is the honorific form of 見る ('see,' used for the listener's act of seeing), and の通り means 'in accordance with,' 'as per.' Together: 'as you can see [with respect].' Common in business, news, and formal speech when something regrettable is already observable to the audience. 残念ながら ('regrettably,' 'unfortunately') is the ~ながら ('while / despite') attached to 残念 (regret, disappointment) — a softener for bad news.
