Two .500 teams collide in Pittsburgh as Seattle’s Ryan O’Hearn brings his hot bat to a pivotal interleague tilt.
500. Seattle holds a slim lead in the AL West, while Pittsburgh sits exactly at the break-even mark in the NL Central, making this a pivotal series for division momentum. Ryan O’Hearn’s bat is the headline attraction.
498 over the last 30 days. O’Hearn is 3-for-8 lifetime against Pittsburgh with a pair of doubles, and manager Scott Servais confirmed he’ll pencil the lefty into the cleanup spot again. Pittsburgh counters with a rotation that has quietly become one of baseball’s most improved units.
92 ERA) in a matchup of right-handers who rank inside the top-15 in Baseball-Reference’s pitcher WAR over the past month. 4 runs per game with O’Hearn in the lineup. This contrast between Seattle’s surging offense and Pittsburgh’s stingy pitching sets up a classic strength-on-strength battle that could define the series.
Servais called the series “a great opportunity to keep the foot on the gas” after Seattle salvaged a split in Texas. Pirates skipper Derek Shelton framed it as “a chance to prove we belong in the conversation” with a win in front of the home crowd. The Mariners have won five straight at PNC Park since 2019, a streak Shelton admitted “stings” when asked about it.
Historical trends aside, both teams are playing their best baseball of the season, with Seattle riding a 7-3 record in their last 10 games and Pittsburgh going 6-4 over the same stretch. The winner of this series could gain a critical edge in the playoff race, while the loser risks falling back into the pack. O’Hearn’s recent tear isn’t just a fluke—it’s a reflection of his adjusted approach at the plate.
Since working with hitting coach Tony Arnerich to shorten his swing, he’s cut his strikeout rate by 10% while maintaining his power output. Meanwhile, Keller’s resurgence for Pittsburgh has been fueled by a revamped slider that’s generated a whiff rate above 40% since May. These individual breakthroughs mirror their teams’ broader narratives: Seattle’s offensive consistency versus Pittsburgh’s pitching overhaul.
The series also carries added weight for the Mariners, who have struggled against NL opponents this season (4-6 record), while the Pirates have thrived in interleague play (5-2). The Mariners’ reliance on O’Hearn has grown in recent weeks, with the 28-year-old accounting for 38% of Seattle’s runs over the last 15 games. His ability to drive in runs with two strikes—he’s 8-for-17 in such situations since May—has been a key factor in the Mariners’ late-game comebacks.
For the Pirates, the challenge extends beyond Keller and the rotation. 58 ERA) nursing a minor forearm tightness that could limit his availability. 89 ERA, 12 saves) converting all five save chances in June.
The interleague format adds another layer of intrigue. Since 2020, the Mariners are 12-18 against NL teams, while the Pirates are 11-9 in the same span. This series marks the first meeting between the two franchises since 2019, when Seattle swept a three-game set in Pittsburgh.
The Mariners’ struggles against NL pitching this year—particularly in close games—suggest they’ll need O’Hearn to continue his hot streak to overcome the unfamiliar competition. For the Pirates, the opportunity to slow down the Mariners’ offense could be a statement win in front of a home crowd eager to see progress in a season that’s been defined by narrow losses. What’s next: The series shifts to Seattle next week, but the Pirates need to solve O’Hearn early to avoid digging a hole in this three-game set.
A split would keep both teams within striking distance of the division lead, while a sweep would hand Seattle a psychological edge heading into the All-Star break. With just 10 games separating the top four teams in both the AL West and NL Central, every matchup from here on feels amplified—and this one could be a turning point for either franchise.

This interleague set is a microcosm of the 2024 race: two clubs with identical win percentages chasing playoff positioning while their best hitters carry the offensive load. O’Hearn’s surge isn’t just a storyline—it’s a barometer for Seattle’s division hopes and a stress test for Pittsburgh’s pitching depth. The outcome will reveal which team’s strength prevails: the Mariners’ bat-first approach or the Pirates’ pitching-first rebuild. The series also underscores the high stakes of interleague play in a compressed schedule, where a single series can reshape playoff narratives before the All-Star break.
