Right now, the biggest thing that the Twins need is someone who can consistently fill the left side of the infield whether at SS or 3B. The lineup looks like it is really coming around, but the offense and defense have been noticeably missing from the left side.
Brendan Harris got off to a fine start, but has since been very ordinary. Mike Lamb has started to come around, but the offense still isn't there. With Alexi Casilla rapidly rising as one of the Twins brightest young stars, he appears to have the 2B position locked up. Then to fill up the infield, Justin Morneau has the 1B spot locked up for the next 6 years. The outfield also is showing signs of life, with Delmon Young starting to come around and Carlos Gomez and Micheal Cuddyer playing fairly well over the last few weeks.
The biggest question mark coming into the season has been the pitching staff. This has been a pleasant surprise thus far. The bullpen took a shot when Pat Neshek went down, but the rest of the 'pen is still as good as ever. The starting rotation has pitched well beyond their years, allowing the Twins to stay in most ballgames. If they can continue to turn leads over to the bullpen, I would look for the Twins to finish in the top 2 in the AL Central. Once they can find players to lock up the left side of the infield with a good combo of offense and defense look out, because this team is full of talent. Once the offense clicks, these team is going to be a force to be reckoned with.
