Brock Rodden's secret strength is unfortunately not what the Mariners need

In the Mariners' latest attempt to save their skidding season, they called up Brock Rodden, their No. 19 prospect, on Friday. Although it eventually ended in heartbreaking fashion for the team, he made a strong debut in the first game of the Astros series and looks like he could find success as a major leaguer.

Unfortunately, Seattle has far too much ground to cover if they want to get back into the postseason picture and an undersized infielder may not be the answer.

Brock Rodden's strengths still don't help plug the biggest hole in the Mariners' lineup

Rodden was a fifth-round selection out of Wichita State University in 2023 and has had strong numbers in the minor leagues, posting a 139 wRC+ in 163 plate appearances for Double-A Arkansas last season. This year, he has a more modest 107 wRC+ over 410 plate appearances for Triple-A Tacoma but he's seemingly added more pop, increasing his ISO from .159 to .237 from 2025 to 2026.

Big league lineups can always use more power but for Seattle, Rodden's pop comes from the wrong side. He can bat from both sides of the plate but if his numbers with Tacoma are any indication, his power is far better as a left-handed hitter (.547 SLG) than as a right-handed hitter (.403 SLG).

At the trade deadline, one of the team's key needs was a right-handed bat. They eventually landed on Taylor Ward who although possessing some real strengths on paper, has been largely ineffective at the plate since joining the team, posting a .188 OPS over his first eight games as a Mariner.

On the other hand, Seattle's offense can use all the help they can get and they can't really afford to be picky at this time. The team's combined OPS of .686 is 28th in MLB and their 486 scored runs is dead last. The Mariners' disastrous offensive results have been a persistent problem and this is far from the first season in recent history where it has been their biggest weakness.

Rodden will hopefully fare better than his fellow prospect Colt Emerson but outside of a historic rookie campaign over the next six weeks, it's hard to see how he alone can get Seattle back to where they need to be. It's not his burden to bear singlehandedly but outside of simply replacing an injured Emerson, it's difficult to see how his presence will meaningfully move the needle.
