Entering the 2012 season rated by Baseball America as having the best strike-zone discipline in the Orioles organization, Kelly holds the fourth-best combined on-base percentage of anyone in Minor League Baseball with a .448 mark between his time in Frederick and brief 11-game stint in Triple-A Norfolk.
This is the third time in four weeks a Key has won Player of the Week honors and fourth time overall this season. Aaron Baker won the award twice and Ronnie Welty did so back in mid-April.
Along with Kelly's .346 average and .460 OBP being the best among active Carolina League players, his .973 OPS also ranks first.
Kelly, known for his innate ability to draw walks, has 54 on the year while holding a 16.7% walk rate, both of which are second among active players.
In addition to his plate discipline, Kelly's .513 slugging percentage is third among active players. In addition to his three home runs hit in the past week, Kelly has nine on the year for Frederick, which dwarfs his previous career high of four.
Kelly spent 11 games with Triple-A Norfolk from May 13th - 26th, where he went 10-for-36 with a double, home run and four walks, totaling a triple slash line of .278 / .350 / .389.
This is Kelly's fourth professional season after getting drafted in the 13th Round from UC-Davis in 2009. The 23-year old, who will be turning 24 on Friday, has been an all-star with Frederick, the Delmarva Shorebirds, and Aberdeen IronBirds. Kelly holds a career slash line of .280 / .378 / .374.
