Adam Jones just homered to right-center field on a 2-1 pitch to give the Orioles a quick 1-0 lead.
Nolan Reimold flied to right before Jones stepped to the plate against Marlins starter Ricky Nolasco. Jones has three homers and five RBIs this spring.
Nick Markakis followed with a single into center field.
Update: Jeremy Guthrie retired the first two batters, getting a called third strike on Cameron Maybin, but he walked Hanley Ramirez and gave up a run-scoring single to Jorge Cantu. Ramirez stole second before Cantu singled with the count full. Guthrie threw 23 pitches, 11 for strikes.
