Bryce Harper has played well, but not tremendously at the Double-A and Triple-A levels, up until his promotion to the Nationals for Saturday's game. The 19-year-old outfielder has a weakness against off-speed pitches. "This looks to me like a panic move, a reaction to modest attendance figures for the Nats despite their hot start this year, rather than a well thought-out developmental plan, as we've seen the club employ for most of its other prospects," writes ESPN.com's Keith Law. Harper doesn't even have 90 at-bats at the Triple-A level.
