Hirano was credited with his 27th hold of the season in Tuesday's 6-4 win over the Rangers after inducing a double play to end the eighth inning.

EDGE Analysis

After lefty specialist Andrew Chafin exited with one out and a runner on first base, Hirano stepped in and got Elvis Andrus to ground a dribbler back to the mound, igniting a 1-4-3 double play. The 34-year-old rookie has remained effective through 10 appearances in the second half, ceding only two runs over 10.2 innings and scattering five hits and two walks.

Hirano retired all four of the batters he faced en route to earning his 24th hold of the season Sunday in the Diamondbacks' 5-4 win over the Padres.

EDGE Analysis

Hirano was summoned in relief of Clay Buchholz, who recorded the first two outs of the sixth inning and exited with runners on first and second base and the Diamondbacks clinging to a 5-3 lead. The rookie extinguished the San Diego threat by inducing an inning-ending grounder from Jose Pirela, then returned for the bottom of the seventh and coaxed a pair of groundballs and punched out another hitter to put away the side. It was Hirano's 32nd scoreless appearance in his last 35 outings, with the right-hander tallying a 1.69 ERA and 1.09 WHIP over that stretch.

Hirano was the pitcher of record in Saturday's 6-5 loss to the Rockies. He worked 1.2 innings and gave up a run on two hits and a walk and struck out two.

EDGE Analysis

After stringing together 26 consecutive scoreless appearances from May 6 to July 3, Hirano has ran into some turbulence of late. Over his last six outings, he's given up nine runs (six earned) on 10 hits and two walks over 5.2 innings. The recent struggles won't result in the Diamondbacks moving him out of a setup role, but fantasy owners who have been relying on Hirano for ratio help may want to see him iron things out over his next few appearances before inserting back into lineups.

Hirano retired just one batter and surrendered four runs on four hits in Wednesday's 19-2 loss to the Rockies.

EDGE Analysis

Hirano turned in scoreless appearances at Colorado on June 8 and 10 in his first career outings at the park, but the Coors Effect reared its head Wednesday. Typically used in the seventh or eighth inning, Hirano was summoned in the bottom of the fourth after starter Shelby Miller and reliever Jorge De La Rosa ceded 12 runs over the first three frames. Hirano didn't fare any better, generating a flyball out before yielding four consecutive hits and receiving the hook. The rookie's season ERA jumped nearly a full run after the disastrous outing, moving from 1.36 to 2.25.

Hirano yielded a single and hit a batter with a pitch but tossed a scoreless seventh inning to notch his 20th hold of the season Friday in the Diamondbacks' 3-1 win over the Padres.

EDGE Analysis

Hirano needed 21 pitches to get through the seventh but was ultimately successful in preserving the Diamondbacks' one-run lead. With runners on first and second with one out, Hirano induced a Wil Myers dribbler back to the mound and started a 1-4-3 double play to end the threat. It was a nice bounce-back effort from the rookie after he was lit up in his last appearance Wednesday against the Cardinals for four runs (one earned) while retiring just two batters. The blowup ended Hirano's streak of 26 consecutive scoreless outings.

Hirano struck out a batter as part of perfect seventh inning in Tuesday's 2-1 win over the Marlins.

EDGE Analysis

Hirano collected his 18th hold and lowered his ERA to 1.25 while turning in his 24th consecutive scoreless appearance, tying the club record shared by J.J. Putz (2012) and Brandon Lyon (2008). A former standout closer in his native Japan, Hirano has been stellar in a setup role for the Diamondbacks and could get a look in the ninth inning if Brad Boxberger continues to struggle in his subsequent save chances.

Hirano worked around a pair of walks to toss a scoreless seventh inning in Sunday's 5-3 loss to the Mets.

EDGE Analysis

Hirano struck out two batters in the 27-pitch frame to reduce his ERA to 1.45 while collecting his 15th hold of the season. The Japanese right-hander has been as good as advertised since coming over from the other side of the Pacific this winter and should continue to see plenty of high-leverage work out of the Arizona bullpen.

Hirano retired one of the two hitters he faced in Saturday's 6-2 win over the Marlins, giving up a base hit in a 12-pitch appearance.

EDGE Analysis

After starter Zack Greinke was unable to close out the seventh inning, Hirano was summoned to the contest with baserunners on first and second base. Hirano induced a Starlin Castro groundout to end the threat, then allowed a single to begin the top of the eighth inning before getting the hook. Hirano now maintains a 1.84 ERA and 0.85 WHIP across 24.2 innings this season and seems to be the Diamondbacks' clear No. 3 relief option behind closer Brad Boxberger and setup ace Archie Bradley.

Hirano pitched a scoreless seventh inning in Tuesday's 2-1 win over the Brewers, giving up one hit and notching a strikeout.

EDGE Analysis

Hirano has kept the opposition off the board during his last five innings out of the bullpen, allowing only two hitters to reach base during that span. Despite his stellar 2.33 ERA and 0.78 WHIP on the campaign, Hirano likely ranks no better than third in line for saves in Arizona with closer Brad Boxberger and relief ace Archie Bradley both performing well through the first month and a half of the season.

Hirano registered his sixth hold of the season after striking out the side in the seventh inning of the Diamondbacks' 5-4 victory over the Nationals on Friday.

EDGE Analysis

The 34-year-old has been rock solid in his transition from Japan to the majors, as he's now accrued a 1.59 ERA, 0.71 WHIP and 11:2 K:BB across 11.1 innings. Hirano has quickly gained the trust of manager Torey Lovullo and should continue to see ample work in the late innings, but the right-hander likely won't be in the mix for saves so long as both Brad Boxberger and Archie Bradley are healthy and effective.
