Walker struck out four over two scoreless frames while serving as the Giants' opening pitcher in Monday's 10-2 loss to the Rays. He worked around two hits and one walk in the 39-pitch outing.

Walker did his part to the keep the Rays offense at bay, but primary pitcher Tristan Beck (five runs allowed over three innings) was unable to continue the trend once he took over in the top of the third. Expect manager Gabe Kapler to continue making frequent use of Walker as an opener while the Giants have only two locked-in traditional starters at the moment in Logan Webb and Alex Cobb. In nine outings as an opener this season, Walker has produced a 2.40 ERA, 1.47 WHIP and 25.0 K-BB% in 15 innings.

Beck (3-2) allowed five runs on 10 hits and a walk while striking out two over three innings, taking the loss Monday versus the Rays.

Beck took his turn as a bulk reliever Monday, but he couldn't continue the success of opener Ryan Walker, who started the game with two scoreless innings. Beck has lost his last two appearances, and he's at a 6.97 ERA over 10.1 innings across four outings in August. For the season, he has a 3.61 ERA, 1.19 WHIP and 49:16 K:BB through 62.1 innings over 25 appearances while adding two saves and a hold, though his current role makes late-inning assignments unlikely. Beck will likely be available to pitch again this weekend in Atlanta, but the Giants' tendency to have as many as three rotation spots working behind openers makes it tough to pinpoint when he might next take the mound.

Miller (1-0) earned the win Monday against the Pirates. He allowed two walks over two scoreless innings.

Miller made a positive first impression in his Mets debut after being called up from Triple-A Syracuse on Saturday. The right-hander worked around a pair of walks, delivering two scoreless innings to earn his first win of the season. Miller now sports a 5.40 ERA with a 1.35 WHIP and 8:6 K:BB across 13.1 innings this season between the Mets, Dodgers and Brewers. He'll likely fill a middle-relief role in New York going forward.

Mantiply will serve as the Diamondbacks' opening pitcher for Tuesday's game in Colorado, Jody Jackson of Bally Sports Arizona reports.

After taking the loss in relief in Monday's series opener at Coors Field while failing to retire any of the three batters he faced en route to allowing three earned runs, Mantiply will get back on the hill Tuesday and attempt to right the ship. He tossed only 11 pitches Monday, so Mantiply should be able to give Arizona an inning or two before turning the game over to the bullpen. Arizona hasn't named a designated bulk reliever for the day, but manager Torey Lovullo could lean heavily on either Slade Cecconi or Bryce Jarvis, both of whom have started in the minors for most of the season and are available on three days' rest.

Bolton was optioned to Triple-A Indianapolis on Monday.

Bolton had been up as the 27th man for Sunday's doubleheader versus the Reds, tossing a scoreless frame in the nightcap. He's struggled overall at the big-league level this season, allowing 11 runs with a 10:11 K:BB over 11 innings.

Duarte was optioned to Triple-A Louisville on Monday.

Duarte picked up his first career save in the second game of Sunday's doubleheader versus the Pirates, but given he served as the 27th man for the twin bill, he was sent right back down. He's posted a 3.86 ERA with a 16:10 K:BB through 18.2 innings this season.

Edwards (shoulder) started a rehab assignment with the Nationals' Florida Complex League team Monday.

Edwards' first appearance with the FCL Nationals didn't go well, as he allowed three runs while recording just two outs. The veteran reliever has been sidelined since late June with right shoulder inflammation, so he figures to need a few more outings before rejoining the big club.

Ward (shoulder) began a rehab assignment with the Nationals' Florida Complex League team Monday.

Ward yielded a pair of runs over two innings of work in his first game action since going down with a shoulder injury in early July. He figures to require a few more appearances before rejoining the Nationals' bullpen.

Mantiply (1-1) was charged with Monday's loss to the Rockies. He allowed three runs on three hits and did not retire a batter.

Mantiply and Scott McGough combined to cough up an Arizona lead in the eighth inning. Mantiply, who is expected to serve as an opener Tuesday, threw just 11 pitches, so Monday's usage should not prevent him from carrying out that assignment. Since returning to the majors Aug. 1, the left-hander has allowed six runs on six hits and one walk over 4.1 innings.

Romero (3-1) struck out two without giving up a hit or a walk over 1.1 scoreless innings to earn the win Monday over the Athletics.

Romero's usage would typically lead to a save, but the official scorer deemed Giovanny Gallegos' outing brief and ineffective. This allowed Romero to pick up the win instead after the only baserunner he allowed reached on an error. Over six appearances spanning 7.1 innings this month, Romero has given up three runs, seven hits and one walk while striking out 12. He's rapidly ascending the Cardinals' bullpen hierarchy, earning some late-inning looks as the team's top southpaw reliever. He has a 3.72 ERA, 1.03 WHIP and 32:9 K:BB through 29 innings while picking up two saves and three holds this year.
