Cardinals manager Oliver Marmol said Thursday that Gorman (back) could begin a rehab assignment next week, Daniel Guerrero of the St. Louis Post-Dispatch reports.

Gorman was placed on the 10-day injured list last weekend with a lower-back injury that first cropped up before the All-Star break. He was given a pain-killing injection Monday and has evidently responded well enough that he could be cleared for game action shortly. Because Gorman has not missed much time, his rehab assignment should be relatively brief, setting him up for an early-August return.

Koss (hamstring) began his rehab stint in the rookie-level Arizona Complex League on Thursday, and he went 2-for-3 with two runs scored and an RBI in the team's 7-3 win over the ACL Diamondbacks.

Koss played four innings at second base in his first rehab game, tallying two singles. The 27-year-old infielder was placed on the 10-day injured list July 1 due to a left hamstring strain. Before that, Koss had been solid as a reserve infielder for the Giants, slashing .265/.305/.357 with 12 runs scored, 12 RBI, two home runs and two stolen bases across 108 plate appearances.

The Rays designated Montes for assignment Saturday.

Montes never appeared in a game after being recalled from Triple-A on Wednesday, and he'll now be replaced on the active and 40-man rosters by the newly acquired Tristan Gray. Montes owns a .616 OPS through 272 plate appearances in Triple-A this season, though his defensive versatility could offer at least some appeal to teams browsing the waiver wire.

Estrada went 1-for-4 with a two-run home run in Friday's 6-5 win over the Orioles.

Estrada batted sixth in his return from a thumb sprain and helped spark a comeback with a two-run homer in the fourth inning. Through just 129 plate appearances this season, the 29-year-old is slashing .283/.310/.417 with three home runs, 20 RBI, 12 runs scored and a stolen base.

The Yankees optioned Vivas to Triple-A Scranton/Wilkes-Barre on Friday.

Vivas' most recent call-up came July 9 after DJ LeMahieu was DFA'd. Vivas had been trading off starts at third base with Oswald Peraza since, but the Yankees found a full-time starter at the hot corner Friday when they traded with Colorado for Ryan McMahon. In Vivas' most recent stint with the Yankees, he went 2-for-10 with an RBI over six games.

Moore (thumb) has started baseball activities, Rhett Bollinger of MLB.com reports.

Moore was called up by the Angels from Triple-A Salt Lake in mid-June and played in 18 games for the big club before landing on the IL in early July due to a left thumb sprain. His return to baseball activities is an encouraging sign, and the 23-year-old will look to progress enough in his recovery to swing a bat.

The Orioles selected the contract of Jackson from Triple-A Norfolk on Friday, Rich Dubroff of BaltimoreBaseball.com reports.

Jackson takes the spot on the MLB roster vacated by Gregory Soto after he was traded to the Mets earlier Friday. Jackson started the season in Double-A but was promoted to Triple-A last month. He's slashed .377/.398/.682 with 11 home runs, 22 RBI, 28 runs scored and eight stolen bases since the promotion. Jackson is still waiting to make his MLB debut.

The Guardians optioned Wilson to Triple-A Columbus on Friday.

With Gabriel Arias (ankle) back from the 10-day IL, Wilson will head back to the minors. Wilson owns a .167/.250/.222 slash line with four doubles, one RBI, six runs scored, one stolen base and a 7:34 BB:K across 85 plate appearances at the big-league level this season.

The Red Sox recalled Hamilton from Triple-A Worcester on Friday.

The 27-year-old has been at Worcester for the past couple weeks but will rejoin Boston as Marcelo Mayer (wrist) heads to the injured list. Hamilton has a .505 OPS in 62 MLB games this season and is likely to serve as a reserve infielder while up with the big club.

The Rockies optioned Amador to Triple-A Albuquerque on Friday.

The 22-year-old was called up by Colorado on Sunday and had a productive few days in the majors, going 5-for-9 with two doubles, three RBI and two runs in three games. Despite the demotion Friday, Amador could soon rejoin the big club with Ryan McMahon being traded to the Yankees.
