Regex for single digit catches two digit numbers?

2

This regex catches two digit nubers:

if I have y11 it will still catch it, how to match only y0, y1, y2, y3, y4, y5, y6, y7, y8, y9 ?? After the digit there might be a blank space or a letter or a dot.

preg_replace('/y([1-9]{1})/', 'y0$1', $string)

php regex
