Blue Jays Suddenly Have A Bigger Spencer Arrighetti Problem

As Spencer Arrighetti's performance with the Blue Jays falters post-injury, the team's concerns mount with each misfire off his once-dominant fastball.

Spencer Arrighetti showed the Toronto Blue Jays the version they wanted early in the season, but that look has faded fast.

After coming off the injured list and building momentum between April and May, Arrighetti has gone into a steep slide. The Houston Astros right-hander opened his year with seven wins in eight starts, a 1.34 ERA and a 3.98 FIP, and he looked like the kind of arm that could steady an inconsistent rotation. That stretch came with an 8.2 K/9 and a 5.0 BB/9, a reminder that he was still working through long counts, but he was getting strikeouts and finding ways out of trouble.

A big part of that success came from the curveball and sweeper. He was limiting hard contact, and home runs were barely part of the equation. Opponents managed just two homers in his first 47 innings across those eight starts.

Since late May, though, the wheels have come off. Arrighetti is 0-6 over his next 11 starts, and he has not won since May 28, when he held the Texas Rangers to one run over six innings.

That’s not the kind of profile the Blue Jays were hoping for at the trade deadline, but the dominant version of Arrighetti was. The idea was simple: fewer pitches to navigate lineups, more strikeouts, fewer damaging hits and enough durability to matter for a team with offensive issues.

Instead, since his return from the injured list, he has been hard to pin down again. The bigger concern is how comfortable hitters have looked against him.

In six of his last eight outings, he has given up at least one home run. Three of those games featured at least two homers allowed, and in two of them he surrendered three - against the Cleveland Guardians and Detroit Tigers in his final two starts of June.

The deeper issue is even more alarming. Eleven of the 14 home runs Arrighetti has allowed this season have come against his fastball, and nine of those came with the hitter ahead in the count.

His 35.4 Whiff% on breaking pitches drops to 16.8% when he turns to the fastball. So this isn’t just about balls leaving the yard; it’s about a pitch that has stopped playing like a weapon.

Arrighetti’s fastball has gone from a strength to something hitters are hunting. Whether that’s a movement issue, a tell, or a loss of horizontal movement on the four-seam fastball, the result is the same.

After two starts, and with the Blue Jays still trying to solve the problem, hitters keep finding ways to do damage. Toronto’s margin for error keeps shrinking, and Arrighetti needs answers soon.

Blue Jays Roster Shift Puts September Upgrades In Focus

The Blue Jays made a quiet roster move before September, optioning pitcher CJ Van Eyk to Triple-A Buffalo without announcing a corresponding move. Van Eyks minor league season had been solid, but his brief major league looks never really translated into much impact, and the decision opens the door for Toronto to start reshaping its roster as the calendar turns.

September is when the depth chart gets interesting, and the Blue Jays are expected to add three players to their 28-man group. Ricky Tiedemann and prospect Sean Keys are among the names in the conversation, giving the club a chance to reward development while also adding some late-season energy to a roster still sorting out its priorities.

Blue Jays Make A Telling Pitching Change Before Guardians Series

Toronto is leaning on a familiar modern pitching wrinkle as it opens its series against Cleveland, handing the first-inning assignment to Spencer Miles and planning for Spencer Arrighetti to cover the bulk of the game behind him. Miles has been one of the more dependable arms in the bullpen this season, giving the Blue Jays steady innings in 42 appearances with a 5-2 record and a 2.92 ERA, the kind of profile that makes him a natural fit for a short opening role.

The move is also a clear attempt to simplify things for Arrighetti after a difficult start to his Toronto tenure. Acquired in a trade, he has yet to settle in, and the club is hoping the opener setup can ease some of the pressure and help him find a better rhythm while giving the Blue Jays a cleaner path through a lineup that will be tested early.

Blue Jays Face A Tough Myles Straw Decision This Offseason

Myles Straw has given the Blue Jays what they expected on the defensive side, but his fit in Toronto is still going to be judged on more than glove work alone. As the 2026 season winds down, the front office has a decision coming on an $8 million club option for 2027, and Straws uneven offense has made it one of the more interesting calls on the clubs offseason docket.

Toronto does not need to decide immediately, and that matters. The team plans to keep evaluating Straw through the end of the season before settling on the option, which gives him a little more time to strengthen his case. For a club weighing roster value and payroll flexibility at the same time, the final weeks could go a long way toward shaping what Straws future looks like in blue and white. [Read more 🡒]
