Jeremy Guthrie just hit Jorge Cantu in the left side, prompting home plate umpire Doug Eddings to warn both benches.
I don't know why Guthrie would hit Cantu on purpose other than the fact that the Marlins are knocking him around and the Orioles right-hander may have been frustrated after second baseman Scott Moore failed to catch Chris Coghlan's line drive.
Wes Helms gave the Marlins a 1-0 lead with an RBI single in the second and then Coghlan's liner made it 2-0. Hanley Ramirez then stroked a two-run double and the next batter, Cantu, was drilled on a first pitch by Guthrie.
It's 4-0 Marlins after the top of the second.
(UPDATE: I spoke too soon. Matt Wieters just hit in opposite-field three-run homer on a ball I initially thought was going to be a routine flyout to left field. O's back in it).
