Arrighetti has been diagnosed with a fractured right thumb after being struck by a ball during batting practice Monday, Matt Kawahara of the Houston Chronicle reports.

EDGE Analysis

This is a bad break for the 25-year-old right-hander, who was in the outfield playing catch during batting practice and was the victim of a freak accident. A timetable for Arrighetti's return has yet to be established, though he'll presumably miss at least a month if not longer, depending on whether surgery is required.

Arrighetti was struck in the right hand by a batted ball during the Mariners' batting practice ahead of Monday's contest, Chandler Rome of The Athletic reports.

EDGE Analysis

Arrighetti appears to be on the wrong end of a tough break, taking a ball off his pitching hand while playing catch in the outfield. Manager Joe Espada said that the 25-year-old is undergoing tests to determine if he suffered an injury of significance or not. Arrighetti is currently projected to pitch Friday against the Angels and it's unclear if his start is in doubt at this point.

Arrighetti (1-1) took the loss Saturday, coughing up five runs on three hits and three walks over 3.2 innings as the Astros fell 6-1 to the Twins. He struck out three.

EDGE Analysis

All the damage against the right-hander came in the fourth inning, as 10 men came to the plate for Minnesota. Arrighetti got the hook in the middle of that sequence, tossing 42 of 70 pitches for strikes before he left the mound. It was a disappointing stumble after he delivered a quality start in his 2025 debut, and Arrighetti will take a 5.59 ERA and 8:5 K:BB through 9.2 innings into his next outing, which lines up to come at home next weekend against the Angels.

Arrighetti (1-0) got the win Saturday against the Mets, allowing one run on one hit and two walks while striking out five across six innings.

EDGE Analysis

Arrighetti found himself in trouble with two baserunners in the first inning, but he got out unscathed after striking out Mark Vientos. Arrighetti proceeded to retire the next 12 batters and held a 1-0 lead heading into the six inning. He gave up his lone run when he fielded a groundball from Juan Soto and casually tossed it to first base, which allowed Jose Siri to dash to home plate and barely beat out the tag. It was the only blemish in what was a strong start for Arrighetti, who is tentatively slated to start against the Twins on the road next week.

Arrighetti is working on a new two-seam fastball against right-handed hitters this spring, because his four-seam fastball last year was hit hard, Brian McTaggart of MLB.com reports. He only threw the new pitch three times in his last start against the Cardinals, because they had six left-handed batters.

EDGE Analysis

The four-seam fastball got hit to the tune of a .302 batting average and .516 slugging percentage last year, hence the need for a new offering. "[I want to] throw something hard that doesn't get barrelled," he said. "Simply put." The new pitch is still a work in progress for Arrighetti, who already gets good results on his offspeed offerings.

Arrighetti recorded two shutout innings while striking out three and not allowing a baserunner in Saturday's Grapefruit League game.

EDGE Analysis

Arrighetti was shaky in his opening spring outing, handing out three free passes in two innings of work. Saturday's appearance showed improvement, as he threw 17 of his 29 pitches for strikes. Arrighetti will have high expectations in 2025 after maintaining a 3.18 ERA across his final 65 innings to close last campaign.

Manager Joe Espada said Friday that Arrighetti (calf) will pitch out of the bullpen for the weekend series against the Guardians, Chandler Rome of The Athletic reports.

EDGE Analysis

Arrighetti was pulled from his last start Sunday against the Angels due to calf cramping. While he won't return to the rotation for the final series of the regular season, the 24-year-old right-hander could see some work out of the bullpen for a game or two to test out his calf issue ahead of the postseason. In his 11 starts since the All-Star break, Arrighetti has a 3-6 record with a 3.30 ERA, 1.16 WHIP and 74:18 K:BB across 62.2 innings.

Arrighetti said after Sunday's game against the Angels that his calf started cramping during the sixth inning, Chandler Rome of The Athletic reports.

EDGE Analysis

Arrighetti alerted the coaching staff when he started to cramp, and manager Joe Espada made the call to shut the right-hander down. Arrighetti will undergo further testing on his calf, but if there's no lingering issue, his next projected start would take place on the road against the Guardians. The 24-year-old right-hander allowed two runs on five hits while striking out six over six innings in a no-decision Sunday.

Arrighetti (7-13) allowed two runs on eight hits and a walk while striking out three over five innings, taking the loss versus the Padres on Monday.

EDGE Analysis

Arrighetti allowed an RBI double to Manny Machado in the first inning and a solo home run to Jackson Merrill in the fourth. This was Arrighetti's third straight outing without a win, though he's limited opponents to two runs or fewer in four of his last five starts. The rookie right-hander is now at a 4.68 ERA, 1.43 WHIP and 161:62 K:BB through 136.2 innings over 27 starts. His next start is projected to be at home versus the Angels.

Arrighetti allowed two runs on seven hits and a walk while striking out seven over 6.2 innings in a no-decision versus the Athletics on Tuesday.

EDGE Analysis

Arrighetti gave up a run in each of the first two innings, including a solo home run to Zack Gelof, but he was able to settle in after that. This was a good bounce-back performance for Arrighetti after he failed to complete one inning in Cincinnati in his previous start. The rookie right-hander is now at a 4.72 ERA, 1.42 WHIP and 158:61 K:BB through 131.2 innings over 26 starts this season, though he's allowed three or more runs just four times in his last nine starts. Arrighetti is projected to make his next start at San Diego with the Astros expected to use a six-man rotation this week.
