This game might be tied if the Orioles had not gotten that call at first base, and I don't blame Charlie Manuel one bit for getting himself thrown out over it. Jimmy Rollins did a great job to evade Ty Wigginton's tag and was not out of the baseline. First base umpire Larry Vanover was not in great position to see whether the tag was made, but assumed that it was instead of asking home plate umpire Larry Reliford for help on the call.
I'm guessing he'll use the baseline argument to defend the call after the game, but it was just a bad decision not to ask for some help to get it right.
No reason for O's fans to feel bad about it. The Orioles have been on the wrong end of their share of bad calls this year, so maybe they really do even out.
