Astros general manager Jeff Luhnow said yesterday that No. 1 overall pick Mark Appel will likely be shut down for the season after making two more starts at Single-A.
Appel has thrown 134.1 innings between college and the minors, so the Astros will stop him from going much beyond 140 total even if that means missing the Midwest League playoffs.
Luhnow indicated to Brian McTaggart of MLB.com that Appel “is probably getting fatigued,” which would help explain his underwhelming 4.50 ERA in 28 innings as a pro. Of course, his 24/6 K/BB ratio is considerably more impressive, although that’s still not particularly great for a college ace facing rookie-ball and low Single-A hitters.
