Jack Flaherty Ready to Turn Corner as Tigers Host Giants

Wins have been elusive, but Jack Flaherty isn’t losing faith. As the Detroit Tigers gear up for Game 2 of their home series against the San Francisco Giants, the spotlight shines on Flaherty—who believes he’s close to a breakthrough.

Despite the Tigers dropping eight of his 10 starts, the veteran right-hander has shown signs of sharpening, especially in his last two outings. Against Toronto and Arizona, Flaherty logged his longest outing of the season and struck out six while limiting hard contact.

And now, he’s up against one of the National League’s premier arms in Logan Webb, with the Tigers seeking to build on Monday’s 3-1 victory.

Flaherty Focused on Progress, Not Perception

Flaherty’s 2-6 record and 4.39 ERA don’t tell the whole story. Over his last two starts, he’s allowed just five runs over 12.1 innings, and appears more comfortable in his command and approach.

He held the Blue Jays to two runs in 5.2 innings on May 16, then followed it up by limiting Arizona to three runs on three hits across 6.2 innings—his deepest start in 2025.

What’s changed? Flaherty credits mindset and mechanics working in sync.

What the Tigers Need from Him

Detroit doesn’t need Flaherty to be perfect—they need him to be reliable. With a bullpen that was stretched in Monday’s opener and a lineup still finding rhythm, a quality start on Tuesday could set the tone for a series win.

Flaherty has struggled against the Giants in his career, owning a 1-2 record with a 5.26 ERA in five starts, but this version of him appears closer to the All-Star form that made him a frontline starter in St. Louis.

Logan Webb: The Giants’ Workhorse Looks to Rebound

Logan Webb has been San Francisco’s ace again this season, but his last outing was a hiccup. Against Kansas City, Webb allowed six runs (three earned) and 10 hits in just four innings—his shortest outing since Opening Week.

That said, he’s been sharp nearly every other start. Webb has allowed two or fewer earned runs in seven of his 10 appearances, boasting a 2.67 ERA and continuing to be a model of consistency.

Webb vs. Tigers: Dominance in Small Sample

Webb’s history against Detroit is impressive. He’s 1-1 with a 0.77 ERA in two starts and has 14 strikeouts over 11.2 innings.

In last year’s win, he held the Tigers to one run over seven innings, fanning eight and inducing weak contact.

His formula is simple: command, ground balls, and soft contact. If he locates early, Detroit’s hitters will need to be patient and selective to generate run-scoring chances.

Tigers Take Game 1: Greene Delivers, Bullpen Shines

Monday’s opener saw Riley Greene deliver a clutch two-run single in the fifth inning—enough offense to secure a 3-1 win. The Tigers managed just five hits, but made the most of their limited opportunities.

That kind of opportunistic offense is what Detroit must repeat Tuesday, especially against a starter like Webb.

Bullpen Does the Heavy Lifting

Detroit used five relievers to navigate the final 4.1 innings after starter Matt Manning was pulled early. The group didn’t allow a run and worked around traffic with efficiency, including a key eighth-inning hold by Alex Lange.

Given the bullpen usage Monday, Flaherty pitching deep into Tuesday’s game becomes even more vital.

Key Matchups to Watch

Tigers

• Jack Flaherty vs Thairo Estrada – Can he limit damage from a consistent contact hitter?
• Riley Greene – Confidence should be high after Monday’s heroics.
• Jake Rogers – Needs to manage Webb’s movement and call a tight game for Flaherty.

Giants

• Logan Webb vs Tigers’ top 4 – Early fastball command will dictate success.
• LaMonte Wade Jr. – A walk machine who can flip momentum with patience.
• Michael Conforto – Look for power potential if Flaherty misses location.

What the Tigers Need to Do

• Flaherty must command early and avoid multi-run innings.
• Patience at the plate – Webb thrives on weak contact. Wait for pitches to drive.
• Protect the bullpen – With five arms used Monday, length from Flaherty is critical.

FAQs

Final Take: Bounce-Back Pitchers, Big Implications

Both Jack Flaherty and Logan Webb have something to prove Tuesday night.

Flaherty wants to continue silencing doubts and show why Detroit brought him back this offseason. Webb wants to shake off his shortest outing of the year and reaffirm his status as one of the NL’s most reliable starters.

It’s a duel of stuff vs. strategy, with two fanbases craving momentum.

For Detroit, a win would confirm that Monday wasn’t a fluke—it was a sign of growth. For San Francisco, a bounce-back from their ace could set the stage for a rubber match in Game 3.
