Chi Chi to the rotation, Detwiler now a reliever

The Texas Rangers have announced that 23 year old righthanded pitcher Chi Chi Gonzalez will be called up on Saturday and make his major league debut in a start against the Boston Red Sox.  The beat guys on Twitter are saying that this is not a spot start -- Gonzalez will be a member of the rotation, and Jon Daniels is being quoted as saying that it is "his spot to lose."

Gonzalez, of course, was in the mix for a spot in the rotation this spring, but was sent down AAA to start the season.  Gonzalez, the Rangers' first round pick in 2013, has just 116 IP above A-ball, but had an impressive campaign in 2014 (2.67 ERA in 138 IP between high-A and AA), and has put up a 4.15 ERA in 43.1 IP over 8 starts for Round Rock this year.

You can read the write-up I did on Chi Chi back in January here.

Meanwhile, Ross Detwiler, who was in the rotation until he went on the disabled list a couple of weeks ago, will be making a two inning rehab appearance for Frisco tomorrow.  However, per the beat guys on Twitter (once again), Detwiler is no longer being considered a starting pitcher -- he is going to be pitching out of the bullpen.  Detwiler is a lefty who has had success in the pen in the past, and his moving to a relief role, and likely activation from the d.l. in the near future, should have incumbent lefties Sam Freeman and Alex Claudio sweating a little bit, as one of them is likely to lose his 25 man roster spot once he returns.
