Chafin gave up three hits and three earned runs in just two-thirds of an inning in Tuesday's loss to the Pirates. His season ERA rose to 7.88.

Chafin wasn't the only Diamondbacks pitcher to get roughed up, as the staff allowed 12 earned runs. However, the lefty's struggles are a bit perplexing after he posted a 2.76 ERA in 2015 across 75 innings, which was most among the team's relievers. Still, his FIP sits at 2.94, suggesting his ERA will come down. Chafin remains Arizona's top left-handed option out of the bullpen.

Miller (1-6) took the loss in Arizona's 12-1 defeat at the hands of the Pirates on Tuesday, surrendering six runs on eights hits and four walks while striking out just three in five innings.

Miller has been awful for the Diamondbacks, failing to pitch more than six innings all season, and allowing three or more runs in seven out of 10 starts and exactly two in each of the other three. The 25-year-old is now 7-23 since the start of 2015, and his 6.56 FIP indicates that things aren't projected to get much better. Even facing a subpar Padres lineup in his next start likely won't be enough to get Miller going.

Nelson went six innings allowing one run on four hits and three walks while striking out eight in a no-decision against the Braves on Tuesday.

The 26-year-old righty posted his third consecutive quality start, and he lowered his ERA under 3.00 for the first time since April 15. His value remains at an all-time high, and he will look to maintain this recent run of success in his next start Sunday against Cincinnati.

Pomeranz didn't factor into the decision Monday in San Francisco despite pitching seven innings of two-hit shutout ball with four walks and four strikeouts.

Pomeranz was dominant all night, but never really had a chance to win with Padre-killer Johnny Cueto pitching a two-hit, complete-game shutout for the opposition. The only negatives about the 27-year-old's performance were his four walks, as they built up his pitch count to 111 even though he largely cruised through seven innings. He deserves better than a 4-4 record based on his 1.70 ERA, but such is life for pitchers in San Diego. Pomeranz will look for better luck Sunday in Arizona.

Johnson (back) will throw live batting practice tomorrow before going to Arizona to continue his rehab, Tommy Birch of the Des Moines Register reports.

The timetable for his return to the rotation at Triple-A Iowa is unknown, but it seems likely that he'll be out until at least early June given that the Cubs want to send him to Arizona before he rejoins his teammates in the Pacific Coast League.

Alvarez has been designated for assignment by the Mets.

The move was made to clear a 40-man roster spot for Ty Kelly. If he clears waivers, Alvarez could stick in the Mets' organization at Triple-A, but he's posted a 9.98 ERA and 2.12 WHIP through 17 appearances at Las Vegas in 2016.

Castro tossed a scoreless inning in the Rockies' loss to Pittsburgh on Monday afternoon.

After spending a month at Triple-A, Castro has come back to fire a pair of scoreless frames for the Rockies. With a 9:2 K:BB over eight innings, he's quickly becoming one of the more reliable options in the Colorado bullpen. As a result, it would hardly be surprising to see him used in higher-leverage situations in the coming weeks.

Melancon recorded the final two outs of Monday's win over Colorado to earn his 15th save of the season.

Jared Hughes started the inning, but he allowed a run on two hits before exiting. Melancon allowed one hit before closing the door, but the appearance lowered his season ERA to 2.33. He's now 15-for-16 in save chances this season.

Boscan earned his first career win Monday after tossing four innings out of the bullpen against the Rockies.

Making his second MLB appearance, Boscan took over in the third inning after Ryan Vogelsong was hit in the face by a pitch during his at-bat in the bottom of the second inning. Boscan struck out two and walked one, while holding the Colorado offense to two runs in his four frames. He also chipped in his first hit with a two-out RBI single. Boscan will continue to work in long relief for the Bucs as Juan Nicasio will take the ball for Saturday's game at Texas since Vogelsong's start was only spot duty to rest Nicasio for a few extra days.

Maurer allowed a run on a solo homer to Howie Kendrick in the Padres' win over the Dodgers on Sunday.

He was working the eighth inning with a one-run lead at the time of the long ball, as Maurer appears to be the preferred setup option (along with Ryan Buchter) to San Diego closer Fernando Rodney right now. Despite having 29 strikeouts in 22 innings, Maurer has struggled at times this season thanks to inconsistent control (12 walks) and a pair of homers allowed in his last two outings, which have pushed his season ERA from 3.60 to 4.50.
