The Rockies recalled Anderson from Triple-A Albuquerque on Sunday.

The right-hander was demoted to Triple-A on Monday but is back with the Rockies with Seth Halvorsen (elbow) landing on the injured list in a corresponding move. Anderson surrendered five earned runs over one innings during his lone appearance with Colorado following his call-up in late July.

The Rockies placed Halvorsen on the 15-day injured list Sunday due to a right elbow strain.

Halvorsen's elbow acted up Saturday, prompting the Rockies to pull him from the contest midway through Spencer Horwitz's at-bat. Though Dugan Darnell ended up finishing out the contest, Victor Vodnik and Juan Mejia could be the top options for saves while Halvorsen is on the shelf. According to Patrick Saunders of The Denver Post, the right-hander will undergo an MRI on Sunday, and he's likely to miss more than the minimum 15 days. Halvorsen has converted 11 of 14 save chances while providing a 4.99 ERA, 1.56 WHIP and 36:21 K:BB in 39.2 innings on the season.

The Mets designated Garcia for assignment Sunday.

The right-hander was claimed off waivers by the Mets on July 21, and he pitched well in six appearances with three runs allowed and a 13:3 K:BB over eight innings. Garcia surrendered two earned runs Saturday versus the Giants, however, and has now lost his place on the 26-man active roster and 40-man roster. Austin Warren was called up from Triple-A Syracuse in a corresponding move.

The Mets recalled Warren from Triple-A Syracuse on Sunday.

Warren has had a few brief stints in the majors this season and has given up one earned run with a 4:3 K:BB over 5.1 innings with the Mets. He's been less effective in 24 outings with Syracuse this season with a 5.20 ERA and 1.41 WHIP.

Richardson was brought up from Triple-A Louisville to serve as the 27th man for Sunday's game against Atlanta.

After the Speedway Classic was suspended Saturday in the first inning following multiple rain delays, Atlanta and Cincinnati will resume the game Sunday. Because starter Chase Burns won't pitch after tossing a perfect inning a day earlier, the Reds will lean on a slew of relievers to get them through the contest. Richardson will be a candidate to head back to Louisville immediately after the contest.

Romero allowed one run on two hits and one walk over 1.1 innings to earn the save Saturday against the Padres. He did not record a strikeout.

The left-hander recorded the final out of the eighth inning and returned for the ninth to notch St. Louis' first save since trading former closer Ryan Helsley, though Romero didn't have his cleanest performance. Still, the 29-year-old has been a reliable high-leverage option this season, with Saturday's earned run being the first he's given up since June 26. Riley O'Brien and Gordon Graceffo could also be in the mix for saves, but it's notable that Romero received the first opportunity.

Thielbar (2-3) allowed two runs on two hits and a walk while retiring only two batters to take the loss in Saturday's 4-3 defeat to the Orioles.

After seven scoreless innings from starter Matthew Boyd, relievers Ryan Brasier and Thielbar coughed up the lead in the eighth. The key play was a three-run home run by Gunnar Henderson off Thielbar, which saddled the veteran lefty with the loss. Thielbar still has a strong 2.36 ERA and 0.86 WHIP across 42 innings this season, and he should remain a key piece of Chicago's bullpen despite the hiccup.

Faucher earned a save against the Yankees on Saturday, striking out one batter in a perfect inning of work.

The Marlins led 2-0 when Faucher entered in the ninth frame, and he preserved the shutout by retiring the side in order on 12 pitches. Miami's bullpen hierarchy has been difficult to nail down for much of the season, but it appears Faucher could be settling into the closer role -- he's picked up three of the team's past four saves, with the only save that went to another pitcher during that span being a four-inning conversion by Tyler Phillips. Faucher has earned the confidence of manager Clayton McCullough by giving up just two runs over 10.2 frames while posting a 13:4 K:BB across 10 appearances since the start of July.

Cox allowed one run on three hits while retiring one batter (on a strikeout) Saturday against the Reds before the game was suspended due to inclement weather.

Cox was pressed into starting duties after Spencer Strider was scratched due to a weather delay that lasted well over an hour. Cox tossed 17 pitches in the rain in the first frame before the game was halted and ultimately suspended. Atlanta reportedly was set for a bullpen game, so Cox's outing wasn't likely to last much longer even if the contest had continued. The matchup is scheduled to resume Sunday afternoon and Cox is eligible to return to the mound, but it's unlikely Atlanta will send him back out.

Cox will open Saturday's game against the Reds after Spencer Strider was scratched due to a weather delay, Gordon Wittenmyer of The Cincinnati Enquirer reports.

Strider had already completed most or all of his warmup before the delay -- which lasted well over an hour -- was announced, so Atlanta decided not to put the star hurler on the mound. Cox will instead open what's slated to be a bullpen game. The lefty hasn't tossed more than two innings in any big-league appearance this season, though he did go 3.2 frames and throw 60 pitches in a start with Triple-A Gwinnett the last time he was on the mound (July 24). Therefore, he's well-rested and stretched out enough to handle a few frames if Atlanta opts for that approach.
