Two first-round prospects from this past year's draft are dealing with minor, and very different, injuries before they can get their first full season started.
Last year's top overall pick Mark Appel underwent appendectomy surgery last week, the Astros announced. He is not expected to miss any time this season but could be pushed back in his preparation for the start of spring training.
An appendectomy shouldn't have any affect on Appel's pitching ability, but it will zap his strength for the start of his spring. The Astros aren't too concerned, and rightly so, but expect them to take it easy with Appel as he works his stamina back up to where it needs to be. He should be fine by the start of the season, but this could serve as a convenient excuse to limit his innings early in the season.
D.J. Peterson, whom the Mariners selected 12th overall in last year's draft, had his season cut short when a fastball broke his jaw late last summer, but as Greg Johns of MLB.com reports, Peterson is back on track and is scheduled to be ready for the start of spring training.
Peterson will be in minor league camp and should be preparing for an assignment to the High-A California League where, if healthy, he could put up some ridiculous numbers. He says his jaw is fine and that there are no ill-effects, but no one can be sure until he steps in there against live pitching and doesn't flinch. Additionally, while the article makes no mention of it, it's hard to believe he won't have to regain some weight and strength after having had his mouth wired shut for a month.
Long-term, however, Peterson should be fine. Much like Appel, the recovery may slightly delay the preperation for his first full season, but ultimately shouldn't be an issue once things get underway.
