The Astros optioned Hernandez to Triple-A Sugar Land on Saturday.

After giving up two earned runs over 2.2 innings during Friday's contest, Hernandez will be sent down to Triple-A for the second time in the last four days. Luis Contreras was recalled from Sugar Land to fill the vacancy in the Astros' bullpen.

The Astros recalled Contreras from Triple-A Sugar Land on Saturday.

Since being moved to the minors in mid-April, Contreras has posted a 3.34 ERA and 1.37 WHIP alongside a 27:19 K:BB through 29.2 innings. He'll now get another shot as a middle reliever for the big-league squad, replacing Nick Hernandez.

The Orioles recalled Hiraldo from Triple-A Norfolk on Saturday.

Hiraldo pitched 1.1 scoreless innings during his MLB debut May 27, but he's turned in a 5.75 ERA and 1.18 WHIP through 20.1 frames in Triple-A since then. He'll rejoin the Orioles' bullpen nonetheless to provide a fresh relief option, replacing Jeremiah Jackson on the active roster.

The Diamondbacks recalled Garcia from Triple-A Reno on Saturday.

Just two days after being traded from Seattle to Arizona, Garcia will join the big-league bullpen to replace Trevor Richards, who was designated for assignment in a corresponding move. Garcia has turned in a 3.51 ERA and 1.38 WHIP through 33.1 innings between Double-A and Triple-A this season, and he's given up one run over two innings so far in his MLB career.

Thompson (lat) said Friday that he's hoping to resume a throwing program within the next "week or two," Daniel Guerrero of the St. Louis Post-Dispatch reports.

Thompson resumed throwing in June following a setback with his left lat in May, but evidently he suffered another setback that has limited him to a strengthening program. The left-hander admitted Friday that he's still feeling discomfort, so a resumption of his throwing program by early August doesn't seem to be a given. Thompson has been sidelined all season with a high-grade left lat strain.

Doval allowed two earned runs on three hits while hitting one batter and striking out three across one inning in Friday's 8-1 defeat to the Mets.

Doval entered the game in the ninth inning, hitting the first batter he faced before striking out the next two. However, the right-hander then surrendered a ground-rule double and threw a wild pitch, allowing a run to score before giving up an RBI single. The 28-year-old has made seven appearances this month, posting a 5.63 ERA, 1.63 WHIP and 10:7 K:BB with two saves and one blown save across eight innings during that span.

The Phillies designated Cusick for assignment Saturday, Scott Lauber of The Philadelphia Inquirer reports.

Cusick will surrender his spot on the Phillies' 40-man roster to make room for Brewer Hicklen, who was acquired from Detroit on Saturday. Cusick, 25, owns an 8.34 ERA and 1.94 WHIP through 22.2 innings in Triple-A this season, making it likely he clears waivers.

Lynch (elbow) will begin a rehab assignment with Double-A Northwest Arkansas on Saturday.

Nerve irritation in Lynch's left elbow landed him on the injured list July 6. Now that he has the green light to return to game action, the left-hander shouldn't require too many tune-up outings before being cleared to rejoin the Kansas City bullpen.

The Yankees reinstated De Los Santos (elbow) from the injured list Saturday.

De Los Santos landed on the injured list in mid-June due to elbow discomfort, but after two rehab outings in the minors, he'll now rejoin the Yankees' bullpen. The 27-year-old carries a 1.80 ERA and a 1.70 WHIP through 20 innings with New York this year and should take on a middle-relief role now that he's healthy.

The Guardians recalled Kent from Triple-A Columbus to serve as the team's 27th man for Saturday's doubleheader versus the Royals.

Kent is likely to stick around with the Guardians just for the day before heading back to Triple-A once the twin bill concludes. The 27-year-old righty has previously made four appearances out of the Cleveland bullpen this season, allowing five earned runs on eight hits and five walks while striking out eight over 7.1 innings.
