Expectations for the Toronto Blue Jays far exceed their current output this season.

The club finds itself battling the Baltimore Orioles and Boston Red Sox simply to avoid the American League East cellar.

The primary culprit behind Toronto’s struggles is an inconsistent starting rotation.

Specifically, the Blue Jays desperately need Shane Bieber and Kevin Gausman to rediscover their form; both pitchers have veered significantly off course.

On paper, Toronto possesses a quartet of starters with impressive track records.

According to FanGraphs, the current rotation consists of:

• Dylan Cease, RHP, Age 30
• Shane Bieber, RHP, Age 31
• Trey Yasavage, RHP, Age 22
• Kevin Gausman, RHP, Age 35

When a fifth starter is required, right-hander Spencer Miles serves as an opener, often followed by veteran left-hander Patrick Corbin.

Assessing the Blue Jays’ Rotation Issues

Dylan Cease: A Bright Spot

The Blue Jays would benefit from more pitchers performing at Dylan Cease’s level.

Cease has long dominated hitters with a blistering 97 mph four-seam fastball paired with a biting slider, complemented by a sinking fastball and changeup.

This season, he is striking out a career-high 13.6 batters per nine innings, though he is also walking 4.1 and allowing 6.6 hits per nine.

On July 3, Cease delivered a gem against the Seattle Mariners, tossing a three-hit shutout with just one walk.

His previous outing against the Texas Rangers was far rougher: 4.2 innings, four earned runs, four hits, and five walks in a loss.

Toronto needs the version of Cease that dismantled Seattle. He reinforced that dominance on July 8 against the San Francisco Giants, carrying a no-hitter into the ninth inning en route to a 10-0 victory with 11 strikeouts.

Cease is not the problem.

The next two arms, however, are in significant distress. To a veteran evaluator, they represent the core of Toronto’s starting pitching crisis.

Shane Bieber: Searching for Consistency

After an injury that sidelined him for most of the first half, Bieber rejoined the rotation on June 23, 2026.

In his debut, limited to 3.2 innings as the team eased him back, he surrendered nine hits, four earned runs, and three home runs while walking none and striking out two against the Houston Astros. He received no decision.

His second start, June 28 against the Texas Rangers, saw him last 5.1 innings, allowing five hits, two earned runs, four walks, four strikeouts, and a home run. Again, no decision.

That totaled four home runs allowed across nine innings.

His third start, July 4 versus the Mariners, was worse: four innings, six hits, seven earned runs, three walks, three strikeouts, and two more home runs in a loss.

Six home runs allowed in 13 innings is unsustainable.

Bieber’s ineffectiveness is a major concern for the Blue Jays.

Following his rough outing, au.sports.yahoo.com reported Bieber stating, “We can definitely be a little more sharp from the get go.”

Kevin Gausman: Far From His Best

Through 19 starts, Gausman carries a 4.32 ERA and 1.22 WHIP—both well above his career norms.

His last four outings illustrate the decline:

• June 19 vs. Chicago Cubs: 2 IP, 7 H, 7 ER, 4 BB, 3 K, 1 HR (Loss)
• June 25 vs. Texas Rangers: 6 IP, 10 H, 6 ER, 2 BB, 4 K, 3 HR (Loss)
• June 30 vs. New York Mets: 6 IP, 5 H, 1 ER, 2 BB, 7 K, 1 HR (Loss)
• July 6 vs. San Francisco Giants: 5.1 IP, 5 H, 4 ER (7 R total), 5 BB, 8 K, 0 HR (Loss)

This is clearly not the Kevin Gausman the Blue Jays require.

Trey Yasavage: A Reliable Rookie

Yasavage has made 13 starts and performed credibly, posting a 4-4 record with a 3.31 ERA and 1.07 WHIP.

He averages 3.9 walks and 5.8 hits per nine innings while striking out 8.3 batters per nine. He has allowed seven home runs across 73.1 innings.

Ultimately, Toronto faces three critical pitching questions:

1. Solidifying a fifth starter role, barring a healthy return from Max Scherzer (back spasms).
2. Getting Shane Bieber—an All-Star and Cy Young winner—to provide length and quality starts.
3. Restoring Kevin Gausman to the two-time All-Star form the club relies upon.

With offensive firepower from players like Kazuma Okamoto and Vladimir Guerrero Jr., the Blue Jays have the lineup to compete. However, their postseason aspirations hinge entirely on Bieber and Gausman rediscovering their equilibrium on the mound.
