Lopez (2-2) allowed six runs (four earned) on seven hits over just 2.2 innings in a disastrous loss Tuesday in Baltimore. He also walked three and struck out two.
This was the worst outing of the rookie's short major-league career, and it completely negates the momentum he had built up with a pair of strong starts in his first two August appearances. Lopez will look to get back on track at home Sunday against the Rockies.
