Seattle Mariners vs Pittsburgh Pirates Recent Form and Pitching Notes
Seattle enters at 41-39 and Pittsburgh at 39-40, with the Mariners holding a 1-0 edge in the series. On June 23, Seattle took the opener 3-2 behind George Kirby (6.0 IP, 2 R, 1 ER, 5 K, 2 BB) and a clean ninth from Andrés Muñoz for his 14th save; Kirby’s outing gave Seattle a stable six innings, and the bullpen covered the final three frames without letting the game slip.
The swing that decided it came in the seventh: Cole Young’s two-run homer flipped a 2-1 deficit into a 3-2 lead, and Cal Raleigh added a solo shot earlier to keep pressure on Mitch Keller (6.0+ IP, 3 R, 4 K, 1 BB). For Pittsburgh, the scoring was built on situational contact (including an RBI single from Marcell Ozuna), but the Pirates couldn’t turn nine hits into more than two runs, and their bullpen had to finish the final innings after Keller exited.
Looking to June 24, Woo’s profile is built on baserunner control (1.00 WHIP) and swing-and-miss, and he’s coming off a sharp June 18 start vs. Baltimore (7.0 IP, 0 ER, 9 K, 1 BB). Ashcraft has been the steadier run-prevention arm overall (3.18 ERA), and his most recent outing on June 17 at Oakland was a quality six innings (6.0 IP, 1 ER, 7 K, 3 BB) that kept Pittsburgh in position to win.

Seattle Mariners vs Pittsburgh Pirates Breakdown
This matchup sets up like a measured, inning-by-inning game rather than a track meet. Woo brings the cleaner WHIP and, at his best, can keep Pittsburgh from stacking rallies; if he’s locating early, the Pirates may be pushed into a “one swing at a time” approach that doesn’t always play well with a low total.
On the other side, Ashcraft has been the more consistent run suppressor, and Pittsburgh’s lineup has been the more productive group on the season by OPS. The Pirates’ slight home-field edge and the marginal moneyline favoritism make sense, but this feels more like a game decided by who converts the one or two biggest opportunities rather than sustained offense.
Seattle Mariners vs Pittsburgh Pirates Best Bet
Under 7.5 (-104) (2 out of 5 units)
Both starters are working with strong season run-prevention indicators (Ashcraft’s 3.18 ERA; Woo’s 1.00 WHIP), and each club has shown it can win games where it has to grind for three to four runs rather than getting there quickly. With the total already tight, the value is modest, but the matchup still leans toward a lower-scoring flow if the early innings stay clean.
