The left side of the Red Sox infield is a huge question mark. Granted, it's not as bad as the situation with the Yankees' left side of the infield. The big difference is the Red Sox have huge upside there.
Xander Bogaerts and Will Middlebrooks could go on to become perennial All-Stars at their respective positions. Then again, Middlebrooks could start out in the minors in 2014 and Bogaerts could struggle to hit .250 in his first full season in the majors.
If that scenario plays out, and Stephen Drew signs with the Mets or Yankees, then Red Sox fans might not be too happy with the Red Sox front office. As for right now, Drew is still waiting by the phone.
I think Bogaerts will adapt well to the majors. Think Manny Machado. Maybe not that good, but, then again, it wouldn't surprise me. The kid can hit. The ball just sounds different coming off his bat. The question will be his defense at shortstop because, well, we haven't seen it at the major league level.
Middlebrooks is more of a question mark. His swing tends to get a bit long and sometimes he seems a bit distracted at third base. Maybe the lack of a certain field reporter standing nearby will make him more focused.
His power is undeniable. From all reports, he has come to camp even more bulked up. Middlebrooks is at his best when he is not trying to pull everything, but instead tries to spray the ball to all fields. That's what I'll be looking for.
