Hutchison (5-4) outpitched Ubaldo Jimenez (2-8), who allowed two runs and three hits in six innings but fell to 0-6 at home.
The difference was Francisco's 11th home run, a second-inning drive into the Baltimore bullpen following a walk to Brett Lawrie.
Hutchison struck out three, walked none and permitted only one runner past second base. The right-hander is 1-3 with an 8.72 ERA at home and 4-1 with a 1.79 ERA on the road.
