CHICAGO — The Chicago White Sox are skipping Carlos Rodon’s next start because of discomfort in his neck and arm.

Rodon was scheduled to pitch Thursday against the Washington Nationals. Miguel Gonzalez will take his place.

Rodon took the loss Friday at Detroit and informed the team he was in pain over the weekend. General Manager Rick Hahn says an MRI showed no structural damage. He also says Rodon was not happy about the decision to skip his turn, but the team was being cautious.

ANGELS: The Angels placed reliever Joe Smith on the 15-day disabled list with a strained left hamstring, one of several roster moves.

Mike Morin was recalled from Triple-A Salt Lake, and fellow right-hander Javy Guerra was designated for assignment to make room for left-hander David Huff.

CUBS: The Cubs placed outfielder Jorge Soler on the 15-day disabled list because of a left hamstring strain and selected the contract of prospect Albert Almora Jr. from Triple-A Iowa.

Reds: Right-hander Anthony DeSclafani threw in the bullpen without problem, and the Reds plan to have him make his first start of the season on Friday against the Oakland Athletics.

The Reds expected DeSclafani to be their No. 1 starter, but he strained an oblique during spring training and has been sidelined.

PIRATES: Top Pirates prospect Jameson Taillon is scheduled to make his major league debut on Wednesday night, getting called up from Triple-A Indianapolis to start against the New York Mets.

The 24-year-old right-hander was the second overall pick in the 2010 amateur draft behind Bryce Harper.

In 10 starts with Indianapolis this season, Taillon has gone 4-2 with a 2.04 ERA and 61 strikeouts in 61 2/3 innings. He missed the last two seasons while recovering from Tommy John elbow ligament transplant surgery and a sports hernia.
