No, if he fields the ball cleanly and doesn't make a bad throw, then it is a single. It happens in baseball all the time...
Official rule:
Rule 10.12(a)(1) Comment: Slow handling of the ball that does not involve mechanical misplay shall not be construed as an error. For example, the official scorer shall not charge a fielder with an error if such fielder fields a ground ball cleanly but does not throw to first base in time to retire the batter.
A fielder's choice would be for the fielder throwing out someone at another base and I make it to first, but that's not happening either.
