Rays Designate Adam Kolarek

The Rays have designated left-hander Adam Kolarek for assignment, Marc Topkin of the Tampa Bay Times reports (on Twitter). Topkin suggests that Kolarek’s vacated 40-man spot will go to infielder Trevor Plouffe, whom the Rays designated Aug. 22 and then outrighted to Triple-A Durham on Aug. 26.

The 28-year-old Kolarek, an 11th-round pick of the Mets in 2010, joined the Rays organization prior to the 2016 campaign and made his major league debut this season. Kolarek struggled over 8 1/3 innings before his designation, giving up six earned runs on nine hits and four walks, with four strikeouts.  He made his 12th appearance with Tampa Bay on Sunday and surrendered an earned run on two hits and a walk over two-thirds of an inning.  That was enough for the Rays to remove him from their 40-man roster.

While Kolarek’s time in the majors has been a struggle thus far, he has turned in excellent work in the minors.  Kolarek has posted a 2.73 ERA and logged 9.4 K/9 against 4.2 BB/9 in 89 Triple-A innings.  Across 43 2/3 frames with Durham this year, he has ridden an incredible 72.6 percent groundball rate and 9.4 K/9 against 3.3 BB/9 to a microscopic 1.65 ERA.
