The Rangers have announced that they’ve placed righty Andrew Cashner on the 10-day DL with a left oblique strain. They’ve also purchased the contract of veteran righty reliever Ernesto Frieri to take his place on the 25-man roster. To clear 40-man space for Frieri, they’ve designated 1B/OF Peter O’Brien for assignment.

Cashner’s injury is the latest for a Rangers rotation that has also recently endured injuries to Cole Hamels and A.J. Griffin, although MLB.com’s TR Sullivan tweets that the Rangers hope Cashner will only need to miss a start or two. Cashner has posted a 3.50 ERA and 49.8 GB% in 69 1/3 innings with Texas, albeit with 4.3 K/9 and 4.0 BB/9.
Frieri is set to return to the big leagues after last appearing in the bigs with the Rays in 2015. He sat out the 2016 season to work on his mechanics, signed a minor-league deal with the Yankees, then latched on with the Rangers after opting out. For the season, he’s posted a 2.86 ERA, 10.6 K/9 and 3.7 BB/9 in 22 Triple-A innings, perhaps indicating he’s recovered some portion of what made him successful as a closer for the Angels in 2012 and 2013 before he struggled with the Angels and Pirates in 2014.
The well-traveled O’Brien has already been a member of four organizations in 2017, heading from the Diamondbacks to the Royals to the Reds to the Rangers in a series of minor transactions. The 26-year-old has demonstrated impressive power, with 122 career minor-league home runs, but has always had trouble with strikeouts and this year has struggled to the tune of a .167/.254/.301 line in four minor-league stops. He briefly played in the big leagues with Arizona in 2015 and 2016.
