Red Sox right-hander Josh Beckett threw 40 pitches in a three-inning, simulated game on Friday. "I felt good," he said. "It's a [simulated] game. There's just not a lot of adrenaline and stuff that goes into that. But I like it when the guys go up there and swing. [It] gives you a little bit of feedback one way or the other. It's hard to get a lot of feedback if the guys don't swing, just not a lot of things that correlate to a game unless you have a little bit of something going on." He experienced mild concussion symptoms after being hit in the left temple on Monday by an errant ball while shagging flies in the outfield during batting practice.
