Same without amsmath:

\[
a
\begin{array}[t]{c}
   xyz \\
   \mbox{text underneath}
\end{array}
b
\]

You can put a \footnotesize inside the \mbox if you want the smaller  
size that obtains with \underbrace.

For inline formulas it is perhaps better to use "tabular":

text with baseline
\begin{tabular}[t]{@{}c@{}}
   $Formula here$ \\
   {\footnotesize Smaller underneath text}
\end{tabular}
following the line
