The Pirates placed Rodriguez (elbow) on the 10-day injured list Saturday.

Rodriguez injured his right elbow throwing a ball to second base while warming up for the second inning of Friday's game against the Phillies. Imaging revealed inflammation in his right elbow, and he will undergo further tests to determine the severity of the injury and an approximate timeline for his return to the majors, per Danny Demilio of PittsburghBaseballNow.com. With Rodriguez and Joey Bart (concussion) both on the injured list, the Pirates promoted Brett Sullivan from Triple-A Indianapolis to serve as the backup catcher behind Henry Davis.

The Pirates recalled Mattson from Triple-A Indianapolis on Saturday.

Mattson has appeared in three games for the Pirates this season, but he has spent most of the year in Triple-A, where he has a 2.42 ERA, 0.95 WHIP, four saves and a 27:6 K:BB across 22.1 innings. He'll take the spot in the Pirates' bullpen vacated by Joey Wentz, who was designated for assignment in a corresponding move.

Dollander will start for Colorado against the Mets on Sunday.

The Rockies shifted their rotation around a bit, moving German Marquez to Saturday while tabbing Dollander to start Sunday. It's not clear when Carson Palmquist, who had originally been deemed Saturday's starter, will take his next turn, though Christian Saez of TheDNVR.com reports that the rookie isn't dealing with any sort of injury. Dollander last pitched Tuesday, so he'll be working on four days of rest Sunday.

Palmquist is no longer scheduled to start Saturday's game against the Mets, as German Marquez will instead receive the start for Colorado.

Per Christian Saez of TheDNVR.com, Palmquist isn't dealing with an injury -- instead, there was simply a miscommunication in lining up the rotation. Chase Dollander is now slated to start Sunday, so it's unclear when Palmquist will take his next turn as a starter.

Marquez will start Saturday's game against the Mets.

Carson Palmquist had originally been lined up to start, but Marquez will get the ball instead Saturday. Per Christian Saez of TheDNVR.com, the change is due to a miscommunication rather than any sort of injury. Marquez last pitched Monday, so he'll be working on four days of rest.

Thomas has been shut down from throwing and is "back to square one" in his recovery from an elbow injury, David Gasper of Athlon Sports reports.

Thomas has been on the IL since early April due to a left elbow injury. Per Gasper, the lefty reliever had loose bodies appear in the affected elbow in late May, and he's now being re-evaluated. It appears Thomas could remain out of action for a significant amount of additional time.

Stowers (hand) isn't in the Marlins' starting lineup again Saturday, though he's available to enter off the bench, Brian Murphy of MLB.com reports.

Stowers will begin on the bench for a third straight contest Saturday as he contends with hand soreness. However, the outfielder entered as a pinch hitter Wednesday and is available to do so again Saturday, so the issue doesn't seem to be a serious concern. Jesus Sanchez is starting in left field Saturday while Eric Wagaman is getting a turn in right.

Atlanta claimed Ruiz off waivers from Philadelphia on Saturday.

Ruiz was designated for assignment by the Phillies last weekend and will now join his fourth MLB organization over the past three seasons. The veteran reliever struggled during his time with Philadelphia this season, posting an 8.16 ERA, 1.88 WHIP and 12:6 K:BB over 14.1 frames. Ruiz will likely take on a low-leverage role in Atlanta's bullpen while he tries to get better results with his new club.

The Pirates designated Wentz for assignment Saturday, Noah Hiles of the Pittsburgh Post-Gazette reports.

Wentz has pitched in 19 games for the Pirates this season, posting a 4.15 ERA, 1.38 WHIP and 22:11 K:BB over 26 innings. His last outing took place back on May 27, when he earned a win in relief by throwing 3.2 innings of one-run ball. Per Kevin Gorman of TribLive.com, both righty reliever Isaac Mattson and catcher Brett Sullivan have lockers in Pittsburgh's clubhouse Saturday, so it sounds like additional moves are forthcoming.

The Dodgers designated Stratton for assignment Saturday.

This is the second time Stratton has been designated for assignment in the past week -- he was previously DFA'd on Monday but cleared waivers and was outrighted to the minors before rejoining the big-league squad Friday. In his latest turn with the team, Stratton allowed one run in one inning against the Cardinals on Friday. Stratton's removal from the 40-man roster makes room for the activation of fellow reliever Michael Kopech (shoulder) from the 60-day IL.
