Narrative:

A B737 landed 28L with a H25 landing 28C. The B737 asked if he should go to ground; I said no; cross 28C at whiskey; thinking that the H25 was landing 28L instead of 28C. Realized my mistake; told the B737 to hold short; but he said he couldn't. I should have switched the B737 to ground control.
