The Diamondbacks reinstated Walston (elbow) from the 60-day injured list Tuesday.

Walston has been on the injured list all season while recovering from a Tommy John procedure he underwent last spring. He was cleared to begin a rehab assignment Aug. 4 and has since given up four earned runs in 7.2 innings at Triple-A Reno. The 25-year-old lefty will join the D-backs' bullpen as a long reliever now that he's fully healthy, though he could still be developed as a starter in the future. Ryan Thompson (back) was placed on the 60-day IL in a corresponding move.

Tovar isn't in the lineup for Tuesday's game against the Orioles.

Tovar will move to the bench for a second time in three games after recording just one hit and five strikeouts in his last 13 at-bats. Cole Carrigg will shift to shortstop to cover for Tovar while Zac Veen, Jake McCarthy and Mickey Moniak start across the outfield.

The Rockies recalled Castano from Triple-A Albuquerque on Tuesday.

Castano has logged a 3.92 ERA and 17:6 K:BB across 20.2 innings with the Rockies this season. The 27-year-old is likely to be used as a multi-inning reliever in Colorado.

The Rockies recalled Amador from Triple-A Albuquerque on Tuesday.

Amador is 3-for-10 with one home run during his time with the Rockies this season and has slashed .264/.367/.428 with 11 home runs and 11 stolen bases in 94 contests with Albuquerque. The 23-year-old is capable of handling both middle-infield spots as well as left field.

The Cubs selected Murray's contract from Triple-A Iowa on Tuesday.

Murray has put together a fine season at Iowa, slashing .294/.395/.500 with 16 home runs, nine stolen bases and a 69:110 BB:K over 118 games. He's primarily a corner infielder but can handle left field as well. Murray is starting at designated hitter and batting eighth Tuesday versus the Brewers in his major-league debut.

The Cubs recalled Ferguson from Triple-A Iowa on Tuesday.

Ferguson has put in some quality work for the Cubs this season in posting a 3.45 ERA, 0.77 WHIP and 19:2 K:BB over 15.2 innings. The 32-year-old will likely be used primarily in a middle-relief role.

The Brewers activated Romero (appendectomy) from the 15-day injured list Tuesday.

Romero underwent an appendectomy in mid-July when he was still a member of the Cardinals organization. He's ready for his Brewers debut now after making two scoreless rehab appearances.

The Brewers recalled Naylor from Triple-A Nashville on Tuesday.

Most teams like to carry a third catcher when rosters expand in September, and that's what Naylor's role will be. He's unlikely to play much, barring injury.

Semien is absent from the lineup for Tuesday's game against the Rays.

It looks to be a routine day off for the veteran infielder. Brett Baty will grab a start at second base in Semien's stead.

The Mets recalled Ross from Triple-A Syracuse on Tuesday.

In 36.1 innings with Syracuse this season, Ross has posted a 6.94 ERA and 45:31 K:BB. The 26-year-old will be making his major-league debut when/if he gets into a game.
