Rays place Andrew Kittredge on IL, select Dusten Knight

The Rays announced that they have selected the contract of right-handed pitcher Dusten Knight, with fellow righty Andrew Kittredge landing on the 15-day injured list due to low back tightness. In order to open a spot for Knight on the 40-man roster, righty JT Chargois was transferred to the 60-day IL.

This will be Knight’s second stint on the Rays’ roster this year, as he had his contract selected in the middle of April but was designated for assignment after just a single appearance. After being outrighted, he’s thrown 16 2/3 innings in Triple-A, putting up an ERA of 3.24 along with a strong 30.6% strikeout rate but elevated 13.9% walk rate.

The loss of Kittredge is an unfortunate one for the Tampa bullpen, as he’s emerged as a key cog in the relief corps. Last year, he threw 71 2/3 innings with a 1.88 ERA, 27.3% strikeout rate, 5.3% walk rate and 53.5% ground ball rate. He racked up eight saves and seven holds on the year as he increasingly earned higher-leverage assignments. His efforts earned him an All-Star selection.

This year, however, things have gone in the wrong direction, perhaps due to this back injury. Over 18 innings, his ERA is an even 3.00, with a 19.7% strikeout rate and 44.2% grounder rate, though he’s limited walks to just 1.5% of batters faced. The club will surely hope that a few weeks of downtime can help him recuperate and regain the form he showed last year.

As for Chargois, he was only able to make a single appearance this year before being placed on the injured list with left oblique tightness. He recently made an attempt to start a rehab assignment, appearing for the Triple-A Durham Bulls on Friday. However, he left after throwing just a single pitch, with Marc Topkin of the Tampa Bay Times relaying that he suffered a strain of that same oblique. He’ll now be ineligible to return until 60 days from his initial April 12 IL placement, though it doesn’t seem like he’s close to a return given this unfortunate setback.
