“He could possibly be in the lineup tomorrow. We’ll make a decision tomorrow, see how he feels, and he could be in the lineup tomorrow. I just didn't reveal it because sometimes if a guy has a day setback, it becomes a huge story. And I don’t want it to become a huge story.”
So as long as Beltran doesn't wake up with pain in his elbow today or hit his funny bone really hard on anything in the clubhouse, he should be good to go. The Yankees have been on a bad streak when it comes to setbacks, so smart move by Joe not saying anything until he knows Beltran is good to go.
Beltran returning could be huge if he truly is over the pain in his elbow. There's no way of knowing how long that will last, but with Joe planning to use him as the primary DH he should be able to limit the wear and tear on that elbow. The more Beltran can give them, the better.
** UPDATE 10:37 AM- Beltran has indeed been activated, with Scott Sizemore getting sent down, and is batting 5th in today's lineup as the DH. **
