BP Annual Player Comments

YearComment
2014 Due to publishing agreements, the 2014 player comments and team essays are only available in the Baseball Prospectus 2014 book (available in hardcopy, e-book, and Kindle).
2013 Lo has good stuff—a sinking fastball and several breaking pitches—and the polish and mental toughness one would expect from a veteran of international competition. He carved up advanced hitters in the Arizona Fall League, indicating he's likely not far from being ready to contribute to a major-league bullpen despite his lack of American professional experience. That's assuming his arm stays intact long enough for that to happen.
2011 Chia-Jen Lo's expected quick ascent through the Astros' farm system was slowed in 2010 by a partially torn ulnar collateral ligament in his elbow that did not require surgery but effectively ruined his season.
2010 The rare Far East add-on for the Astros, and a sign of progress as far as Wade's willingness to start casting a wider net to shore up the farm system. A Taiwanese import who'd starred on his country's Olympic squad, Lo made a solid stateside debut using an effective mix of low-90s heat, a sinker, and a few flavors of breakers, and followed up his summer with a nice turn in the AFL. He needed to move fast, but he has so far, which gives him a shot at making the majors in 2010 if he continues to sling strikes at the upper levels.
