Abreu's second RBI today shows his value. 1st of all, he got the first RBI of the game (Hell, he batted in all of the Sox's runs today).
Back on topic. The bases loaded against a young guy throwing 100 mph, less than two outs. You have got to put that ball in play. Anderson with his .330 or so average strikes out on three pitches. Abreu, and experienced veteran not in anyway in decline, gets his bat on a ball and the slow roller to 3rd scores the insurance run. You guys who complain about his bat slowing down and all that BS, that was a great at bat, great: a clear compare and contrast between Abreu and Anderson. Yes, he got lucky, but his skill was putting the ball in play to get lucky.
And he will continue being this lucky for years yet. Pay the man: three years and at least 36 million.
And if you think the Sox showing a valued warrior the respect and paying him what he deserves will keep them from signing some other free agent, you're just being ridiculous. If you have to reach to that level of fantasy to argue against Abreu's value and why he should not be resigned. You're already lost the argument.
