Why does 3-hydroxy-butan-2-one give a positive Tollens' test despite the absence of an aldehyde group? What is the mechanism?

From the Wikipedia entry on Tollens 1
Tollens' reagent is a chemical reagent used to determine the presence of an aldehyde, aromatic aldehyde and alpha-hydroxy ketone functional groups
The substrate you have drawn is an alpha-hydroxy ketone.

$\begingroup$ @Abcd: What do you mean by "very vastly presented" and " the specific mechanism" in regard to Waylander's link? Aldehydes are oxidized by Tollens' reagent. So are some other functionalities. A positive test MAY indicate the presence of an aldehyde. $\endgroup$ Commented May 29, 2018 at 17:37
