The Astros placed Arrighetti on the 15-day injured list Wednesday with right elbow inflammation, Chandler Rome of The Athletic reports.

EDGE Analysis

Arrighetti gave up just one run in 6.1 innings while punching out a season-high eight batters during his last start Saturday, but he reported pain in his elbow after a bullpen session Wednesday, per Rome. The Astros could revert to a five-man rotation until the 25-year-old righty returns; meanwhile, Jayden Murray will come up from Triple-A Sugar Land to provide Houston with extra bullpen depth.

Arrighetti didn't factor into the decision against the Angels on Saturday, allowing one run on one hit and five walks while striking out eight over 6.1 innings.

EDGE Analysis

Arrighetti kept the Angels hitless into the third inning before surrendering a solo homer to Zach Neto, which accounted for both his only hit and run allowed. Despite the strong overall line, the right-hander's control issues resurfaced with five walks, a problem that had also plagued him in recent outings. Even so, Saturday's performance brought positives, as Arrighetti set a season high with eight strikeouts and notched his first quality start since returning from the injured list.

Arrighetti (1-5) took the loss Sunday against Baltimore, allowing two runs on six hits and no walks across 5.2 innings. He struck out two.

EDGE Analysis

Arrighetti was stuck with a fifth straight loss despite coming one out short of a quality start. The 25-year-old has been inconsistent since returning Aug. 6 from a four-month IL stint due to a right thumb fracture. He's yielded five runs in two of his four starts and has allowed two runs in each of his other two appearances. Since coming off the injured list, Arrighetti has logged a 6.52 ERA and a 15:10 K:BB across 19.1 innings. He's on track to face the Angels next weekend.

Arrighetti (1-4) coughed up five runs on seven hits and four walks over five innings to take the loss Monday at Detroit. He struck out five.

EDGE Analysis

The Houston right-hander was pitching well through the first four frames, allowing one run on a solo homer by Wenceel Perez in the fourth. Then the floodgates opened in the fifth, as Arrighetti conceded four runs on four hits and two walks, capped by a three-run blast by Riley Greene. The 25-year-old has struggled since his return from a thumb injury Aug. 6, pitching to an unsightly 7.90 ERA, 2.12 WHIP and 13:10 K:BB over 13.2 innings. Arrighetti will look to bounce back in his next start, which currently lines up to be at Baltimore this weekend.

Arrighetti (1-3) took the loss Tuesday against Boston, allowing two runs on one hit and five walks with three strikeouts over five innings.

EDGE Analysis

Arrighetti was hit around by Miami in his first start off the injured list last week and struggled to find the zone Tuesday. The 25-year-old had been sidelined since early April, so it's not too surprising for him to be rusty. That said, he allowed nine runs (seven earned) during his three-start minor-league rehab stint, which doesn't inspire much confidence. He'll look to get back on track in his next start, which is tentatively scheduled to come in Detroit.

Arrighetti (1-2) took the loss Wednesday against the Marlins, allowing five runs on 11 hits and one walk in 3.2 innings. He struck out five.

EDGE Analysis

Arrighetti showed plenty of rust and a lack of command on his pitch locations in his first major-league start since April 5 in Minnesota, surrendering a career-high 11 hits Wednesday. The 25-year-old right-hander did produce 16 whiffs during his abbreviated outing, which was perhaps an encouraging takeaway, but he may have been a bit too aggressive in attacking the strike zone overall. Arrighetti has a rough 7.43 ERA, 1.58 WHIP and 13:6 K:BB over his first 12.2 innings, so he'll try to right the ship during a scheduled home tilt versus the Red Sox his next time out.

The Astros activated Arrighetti (thumb) from the 60-day injured list ahead of his scheduled start Wednesday in Miami.

EDGE Analysis

The right-hander wound up missing almost exactly four months after suffering a fractured right thumb back in early April. Prior to being activated, Arrighetti held a 5.73 ERA and 11:5 K:BB in 11 innings over three rehab starts between Double-A Corpus Christi and Triple-A Sugar Land. He threw 79 pitches in his final rehab outing with Sugar Land last Thursday, so he'll be in line for a somewhat limited workload Wednesday.

Arrighetti (thumb) will be activated from the 60-day injured list to start Wednesday against the Marlins, Julia Morales of AT&T SportsNet Southwest reports.

EDGE Analysis

It was reported earlier in the day that Arrighetti was eyeing a return to the rotation at some point this week, and the club announced after Monday's game that he'll toe the rubber for Wednesday's clash. This will mark the right-hander's third start of the season after his campaign was derailed by a fractured right thumb suffered April 8 during batting practice.

Astros manager Joe Espada confirmed Sunday that Arrighetti (thumb) will be activated from the 60-day injured list to start either Tuesday or Wednesday in Miami, Chandler Rome of The Athletic reports.

EDGE Analysis

Arrighetti is finally ready to rejoin the Houston rotation after he had been on the shelf since April 8 due to a right thumb fracture, which he sustained when he was struck by a flyball during batting practice. The right-hander kicked off a rehab assignment July 19, and over his three outings between Double-A Corpus Christi and Triple-A Sugar Land, Arrighetti turned in a 5.73 ERA, 1.45 WHIP and 11:5 K:BB in 11 innings. He got stretched out to 4.2 innings and 79 pitches in his final rehab outing with Sugar Land this past Thursday, so Arrighetti is unlikely to face any major workload restrictions in his return to the Astros.

Astros manager Joe Espada said Friday that Arrighetti (thumb) "is in a position to make his next start at the major-league level," Chandler Rome of The Athletic reports.

EDGE Analysis

Arrighetti has made three rehab appearances, and despite being roughed up in his last outing Thursday with Triple-A Sugar Land, a return to the majors appears to be around the corner for the 25-year-old right-hander. With Arrighetti pitching Thursday and barring any setbacks, he could be back in the Astros' rotation as early as next week on the road against the Marlins. He made two starts for Houston before landing on the injured list in early April due to a right thumb fracture.
