Hoover was placed on the 10-day disabled list Friday with right shoulder inflammation.

EDGE Analysis

Hoover lasted just nine pitches (one out) before exiting his last outing, and this latest development may help explain the short outing. After an impressive first month to the season (1.86 ERA in April), Hoover struggled in May and June and watched his ERA tick up to 4.18. He'll be eligible to rejoin the big club July 3 should he be ready, though the Diamondbacks have yet to place a timetable on his return. In the meantime, Rubby De La Rosa had his contract selected from Triple-A Reno and will replace him on the roster and in the bullpen.

Hoover retired only one of four batters faced in Tuesday's 7-6 win over the Tigers, giving up a run on three hits.

EDGE Analysis

The Diamondbacks entered the top of the sixth inning with a 6-0 lead, but after starter Zack Greinke recorded two outs and gave up four runs, Hoover was called upon to put out the fire with a runner on base. The right-hander was unable to extinguish the Tigers rally, as he allowed three successive base hits to tie up the game before inducing an inning-ending popout from Ian Kinsler. Though he's still maintaining a career-best 14.5 K/9 rate -- more than double last season's mark -- Hoover is still putting far too many runners on base, which is reflected in his 1.85 WHIP. Diamondbacks manager Torey Lovullo may soon look to avoid using Hoover in big spots.

Hoover was charged with a blown save in Wednesday's 6-5 win over the Pirates in 14 innings after giving up a run in the bottom of the 11th inning.

EDGE Analysis

With the Diamondbacks taking the lead in top of the 11th on Nick Ahmed's solo home run, Hoover was in position for what would have been his first save of the season, but couldn't close the door. He struck out the first two batters of the inning before surrendering a game-tying solo shot to Jordy Mercer, which was the third home run Hoover has given up this season. During his previous stint with the Reds, Hoover was routinely troubled by the long ball, and his proclivity for giving up hard contact could ultimately lead manager Torey Lovullo to turn to Archie Bradley if closer Fernando Rodney -- who also blew a save earlier in the contest -- is eventually cast out of the ninth-inning role.

Hoover collected his fifth hold of the season after retiring both of the batters he faced via strikeout during Tuesday's 5-4 win over the White Sox.

EDGE Analysis

With his fastball velocity up a tick from 2016, Hoover has been able to raise his K/9 rate to a career-high 13.2, but he's still issuing too many free passes, which has been a problem throughout his six MLB seasons. Hoover has at least been able to avoid the home-run ball for the most part, and so long as he continues to do that, he'll remain a key part of the Diamondbacks' late-inning mix.

Hoover surrendered two runs on two hits and one walk over 1.1 innings in Sunday's 5-2 loss to the Rockies. He recorded two of his four outs via strikeout.

EDGE Analysis

Hoover maintains a 3.00 ERA on the season thanks in large part to his career-high 13.5 K/9 rate and the ability to avoid the long ball. The latter skill escaped him Sunday, as both of the two runs Hoover gave up came on solo homers, with Chris Valaika and Charlie Blackmon both taking him deep. Despite his poor outing, Hoover remains a key part of the Diamondbacks' late-inning mix and could warrant some consideration for closing duties if veteran Fernando Rodney is eventually removed from the role at some point.

Hoover tossed a scoreless inning in relief during Thursday's 6-2 win over the Padres.

EDGE Analysis

Though the Diamondbacks held a four-run lead when Hoover entered the game in the top of the ninth inning, his appearance did bear some resemblance to a save situation and perhaps gave manager Torey Lovullo a glimpse of how the right-hander would perform in such a scenario. In generating three groundball outs in 12 pitches, Hoover seemingly aced the test, and it appears likely that he'll be the leading candidate to close out games in the event that the struggling Fernando Rodney is removed from the role. Rodney has converted 6-of-7 save chances this season, but owns a bloated 11.00 ERA and 2.11 WHIP to go with a 11:5 K:BB ratio over nine innings.

Hoover scattered two hits and struck out three batters over two scoreless innings en route to collecting his first win of the season in a 4-2 victory over the Dodgers on Monday.

EDGE Analysis

Issues with keeping the ball in the park had doomed Hoover over his last three seasons with the Reds, and though he doesn't benefit much from calling Chase Field his home park these days, he's quickly cemented himself as one of the top setup options to closer Fernando Rodney. Hoover has supplied a 2.70 ERA and 8:1 K:BB ratio over 6.2 innings on the season, with only one of the seven hits he's allowed going for extra bases.

Hoover has earned a spot on the Diamondbacks' Opening Day roster, Nick Piecoro of AZCentral.com reports.

EDGE Analysis

The veteran right-hander signed on as a non-roster invitee this spring and made the most of his opportunity. He fired 10.2 scoreless frames while fanning 12 batters and walking just one this spring. He'll slot in as a middle reliever out of the Diamondbacks' bullpen.

Hoover signed a minor league contract with Arizona on Friday, Joe Trezza of MLB.com reports.

EDGE Analysis

The deal includes an invitation to spring training and could be worth up to $900,000 if he makes the team. Hoover had a disastrous end to his time in Cincinnati, posting a 13.50 ERA over 18.2 innings before being demoted to Triple-A Louisville. The 29-year-old joins a D-Backs bullpen which allowed 311 earned runs in 2016, second most in the majors.

Hoover will not be re-signed by the Reds, Mark Sheldon of MLB.com reports.

EDGE Analysis

According to general manager Dick Williams, "it's not in the plans to have him [in Cincinnati]". Hoover spent a bit of time as the Reds closer and is still arbitration-eligible, but the fact that he coughed up 28 earned runs in just 18.2 innings pitched could make things difficult for the right-hander this offseason.
