Update -- The Astros, Orioles, and Mets are all interested in Justin Upton, according to FOX Sports' Jon Morosi.
Original -- Justin Upton has struggled offensively at times this season but he still might be a valuable piece as the trade deadline approaches. Upton is set to become a free agent in the fall, and according to ESPN's Buster Olney, is the "most prominent" corner outfielder available on the market.
When the Padres acquired Upton, the club was hoping he would be able to contribute on a nightly basis. However, Upton has had a comparatively down year and is batting .252/.331/.426 to complement 15 home runs and 49 RBIs. He has also stolen 17 bases and has proven to be a versatile outfield piece for San Diego.
Upton, 27, was coming off of a solid 2014 campaign with the Braves before the Padres opted to add him to their lineup. He batted .270/.342/.491 to complement 29 home runs and 102 RBIs and produced in the middle of Atlanta's order. The Padres might not be able to receive a lot in return since Upton's six-year, $51.2 million contract ends when the season concludes.
Although he might be the best corner outfield option, Upton's status as a rental player could alter his trade value. If a team makes a deal for Upton, that club would lose Upton to free agency with a draft pick to compensate for it. He also batted .196 in June and is batting .125 to this point in July, Olney adds, and as a result is not expected to draw a notable amount of interest.
As the trade deadline approaches, there are few obviously available hitters, with Upton being an exception. He could provide power and can bounce back in the second half but contending clubs might view adding him as a short-term risk. Although there are not any clear hitters expected to be dealt before the end of the month, some could become available as organizations determine whether to buy or sell. Regardless, Upton will likely be a top name to watch over the next few days.
Upton was taken out of Sunday's game, according to CBS Sports' Jon Heyman.
