After a slow start to their season, the Yankees are the hottest team in baseball.
They have the best record in the majors at 57-34, and lead the second-place Orioles by 10 games in the American League East. Still, New York is looking to improve its roster.
The Yankees are third in the AL in runs scored, but have had their troubles when trying to drive home runners in scoring position. New York is set at essentially every offensive position, except for the outfield.
New York hasn't had a regular left fielder all season long. Brett Gardner was the team's starting left fielder in 2011, playing in 159 games. This year, he's missed all but nine with an elbow injury and doesn't appear to be on his way back any time soon.
The outfielder had another setback on Sunday, and there's no telling when he'll return.
Andruw Jones and Raul Ibanez have filled in admirably in his absence. The two have combined for 24 home runs and 66 RBI, while splitting time at the corner outfield positions.
While Jones and Ibanez have provided the Yankees with a lot of power, they haven't given the team much of anything else. They have a combined batting average of .242 and have stolen just three bases. The two have a combined age of 75, and it will be tough for the Yankees to ask them keep up this pace.
In a lineup that is filled with home run hitters, Gardner provided the club with a different kind of player. Last year, he led the AL with 49 stolen bases and played good defense.
In order to fill the void he's left in the lineup, the Yankees could be in the market for another outfielder. One possible option is the Diamondbacks Justin Upton. According to Bob Nightengale of USA Today, the outfielder undoubtedly will be traded.
Upton is one of the best young players in the MLB, but is set to make a lot of money over the next few years. He's owed $38.5 million from 2013-2015.
He's struggled this year, hitting just 7 home runs and driving in 38 RBI, but has been productive in the past. Upton finished last year batting .289 with 31 home runs and 88 RBI. He also stole 21 bases.
The Bronx Bombers have reportedly inquired about Upton, but aren't close to making a trade. New York would have to give up a few top prospects for Upton, and feel that Arizona is asking for too much in return.
With the way they are currently playing, the Yankees don't necessarily need Upton for this season. However, it wouldn't just be a trade for 2012. Nick Swisher is a free agent in the winter and New York may need to replace him.
Upton is just 24 years old and has shown an ability to be at the top of the league for years to come.
Upton has a no trade clause and could block a trade to the Yankees if he's sent to New York. The Pirates and Blue Jays have also looked into acquiring the outfielder.
