Jackson was optioned back to Triple-A Round Rock on Thursday, Stefan Stevenson of the Fort Worth Star-Telegram reports.

Catcher Robinson Chirinos was activated from the disabled list Thursday, so Jackson will head to Triple-A to free up a spot on the 25-man roster. The right-hander has made five appearances for the Rangers on the season, allowing 11 hits and six earned runs over 7.2 innings. He's fared better at Round Rock, where he holds a 3.68 ERA and 1.36 WHIP.

Devenski has pitched well recently in long relief, compiling a 1.08 ERA, 0.96 WHIP and 11:3 K:BB over over his last 8.1 innings (four appearances).

Devenski, who moved from the Astros' starting rotation to the bullpen a few weeks ago, has a 2.74 ERA, 1.15 WHIP and 39:12 K:BB over 42.2 innings this season.

May retired the only batter he faced in Wednesday's win over Miami. He hadn't pitched since June 1 due to an undisclosed injury.

He had been held out for being "a little sore" according to manager Paul Molitor. However, Molitor said he wanted to work him back into the mix slowly and tried to limit his outing Wednesday.

Colome earned his 17th save in a 6-3 victory over the Diamondbacks on Wednesday.

Arizona recorded two hits and a walk to begin the frame with Paul Goldschmidt coming to the plate, but Colome struck out Goldschmidt and then induced a ground ball double play to end the game. Despite the rocky appearance, Colome remains the Rays closer despite Brad Boxberger healthy again. Colome is 17-for-17 in save opportunities with a 1.00 ERA, 0.93 WHIP and 35 strikeouts in 27 innings.

Mahle was optioned to Triple-A Salt Lake following Wednesday's game against the Yankees, Pedro Moura of the Los Angeles Times reports.

Mahle stuck around despite struggling a lot in his relief appearances but his outing Wednesday appears to have been the final nail in the coffin. The 23-year-old southpaw will now head back to minors for some more seasoning but still has plenty of time to work his way back into the Angels' bullpen.

Kelly has been diagnosed with a Grade 1 strain of his right groin, and will miss his next start for Triple-A Pawtucket, Scott Lauber of ESPN.com reports.

Kelly was roughed up for seven earned runs in his last start for the Red Sox, and was subsequently sent to Pawtucket to work on some mechanical adjustments. Unfortunately, he suffered a right-groin injury in his Tuesday start, which has since been diagnosed as a Grade 1 strain. He will officially miss his next scheduled start, and there is currently no timetable for a return.

Graveman will have his next scheduled start moved up to Saturday against the Reds, John Shea of the San Francisco Chronicle reports.

With Rich Hill (groin) suffering a setback Wednesday, the A's will bump the remaining members of their rotation up by one day. Graveman will be pitching on the road Saturday in the hitter-friendly Great American Ball Park. He has struggled mightily on the road this season, notching a 7.71 ERA with a 1.82 WHIP across 28.0 innings away from his home park in 2016.

May (undisclosed) will play catch off flat ground Wednesday, Mike Berardino of the Pioneer Press reports.

May hasn't pitched since June 1 while he deals with some general soreness, but manager Paul Molitor indicated the reliever may be available Wednesday if the throwing session goes well. The 26-year-old has struggled on the season, so the time off could potentially serve him well provided he's back to full health.

Putnam (elbow) will be available to pitch Wednesday, Colleen Kane of the Chicago Tribune reports.

Putnam hasn't pitched since June 1 as he's dealt with a bout of elbow soreness, but it appears the situation wasn't anything overly serious. He's been a mostly solid option out of the Chicago bullpen thus far, striking out 25 over 23 innings while managing a 2.35 ERA.

Kelly (groin) will likely miss his next Triple-A start, Brian MacPherson of the Providence Journal reports.

Kelly left his last start after suffering a right groin injury and was examined in Boston on Wednesday. It was his first minor league start since being sent down -- he struck out five and allowed three runs over 4.2 innings -- and the club will likely want to be sure Kelly's back to full health before even considering calling him back up.
