BALTIMORE (AP) -- The ball was soaring toward right field, hooking toward the corner, and pinch-runner Alexi Casilla was absolutely certain it was going to drop.
So he took off from first base with one out and the Baltimore Orioles trailing Boston 5-4 in the bottom of the ninth.
"Bad read," Casilla would say later, not too long after he was doubled up to end Saturday's game.
There were plenty of other reasons the Orioles lost, among them an uneven performance by starter Freddy Garcia, Baltimore's inability to build on an early lead and a blown call by home plate umpire Jeff Nelson.
"It's a game where all the little things add up at the end," catcher Matt Wieters said, "and we fell just short today."
Most glaring, however, was Casilla's baserunning blunder.
After Wieters hit a two-run homer off Andrew Bailey to get Baltimore within a run, Casilla broke from first base on a liner by Ryan Flaherty. Shane Victorino made the catch without much difficulty and threw out Casilla for the double play.
"Flaherty hit that ball very good," Casilla said. "He crushed it over my head. I kind of started running and looked where Victorino was playing and thought no chance he was going to catch that ball."
