Texas Rangers starter Ross Detwiler has been placed on the 15 day disabled list with inflammation in his left shoulder, per the beat guys on Twitter.

Detwiler was scheduled to start in Boston on Wednesday. No announcement has been made as to who will make that start, although the leading candidates would appear to be long reliever Anthony Bass and Round Rock starting pitcher Anthony Ranaudo.

Detwiler has been kind of awful this season, with a 6.95 ERA and a 6.06 FIP. He's not struck out many batters, has walked too many, and has allowed a bunch of homers, which is pretty much a recipe for disaster.

I've been of the mind that Detwiler would continue to limp along in the rotation for the time being, with him being a prime candidate to get bumped when one of Martin Perez, Matt Harrison or Derek Holland is ready to come off the disabled list in July (or if the team decides Chi Chi Gonzalez is ready to come up). Now, Detwiler may find himself sent to the bullpen once he comes off the d.l., depending on who replaces him in the rotation.

No corresponding move to add a player to the 25 man roster has been announced, although Tanner Scheppers would seem to be the most likely candidate to get brought up. Since being optioned a few weeks ago, Scheppers has pitched 7.1 scoreless innings for Round Rock.

UPDATE -- Tanner Scheppers has, in fact, been recalled from AAA Round Rock, per the beat guys.

UPDATE II -- Well, this is interesting -- along with Scheppers, the Rangers have also purchased the contract of RHP Ross Ohlendorf. Ohlendorf had an impressive spring and appeared to have the best shot at winning the long man job, but a strained groin sidelined him and put him on the d.l. to start the season.

To make room for Ohlendorf on the roster, the Rangers have designated Kyuji Fujikawa for assignment. Fujikawa was activated from the disabled list earlier this week, appeared in two games, and apparently didn't make much of an impression in those two outings.

The Rangers now have ten days to waive, trade or release Fujikawa.
