Mariners Open Second Half Hosting Struggling Giants

The Seattle Mariners begin the second half of the season on July 17, hosting the San Francisco Giants for a three-game series at T-Mobile Park. The Mariners enter the matchup sitting 1.5 games behind the AL West lead with a 48-49 record, while the Giants find themselves 10.5 games out of a Wild Card spot at 41-55.

Seattle’s performance this season has been defined by a sharp contrast between its pitching staff and offense. The team ranks sixth in MLB with a 3.61 ERA and fourth with a 1.18 WHIP, having allowed the fewest home runs in the league (90). However, the offense has struggled to provide support, ranking tied for 27th with a .230 batting average and scoring the fifth-fewest runs (392).

Conversely, the Giants have relied on a more potent offense that ranks fourth in the league with a .256 batting average. Despite winning three of their final four games before the break, San Francisco’s season has been hampered by pitching struggles, including a 4.46 ERA (22nd) and just 19 saves (26th). This series marks the first meeting between the clubs this year, though the Giants swept the season series in 2025, outscoring Seattle 20-13.

Friday’s contest features a pitching matchup between Seattle’s Bryce Miller and San Francisco’s Landen Roupp. Miller has posted a strong 2.18 ERA and 0.83 WHIP over 57.2 innings. Roupp has logged 97.0 innings this season, holding a 4.27 ERA and 1.31 WHIP.

The game will be available for streaming on Comcast Corporation’s MLB TV platform. Comcast, the parent company of NBCUniversal, operates across cable communications, broadcast television, and film entertainment.
