These 10 Pitchers have owned Mariners hitters during their careers

Troy Percival: 53 G, 56.1 IP, 1.60 ERA, 0.71 WHIP, 21 H, 26 SV, 59 K

We move into the bullpen, and I'm pretty sure there are a lot of people my age or older that see Percival's name on here and aren't surprised. The former Angels closer constantly shut down any hope the Mariners had late in games. When you post a .112/.199/.186 slash line, it makes sense. That makes me throw up in my mouth a little bit to see a team post a SLG of .186 for a full seasons worth of stats against a closer. That 21 hits too... gross.

Joe Smith: 59 G, 52.1 IP, 1.72 ERA, 0.99 WHIP, 37 H, 53 K, 5-1 Record

Yup, the Joe Smith that came over in the Abraham Toro trade from Houston, that's this guy. He owned the Mariners, but not to the same level as Percival. The Mariners hit .198/.266/.283, but only ever got one loss on Smith in nearly 60 appearances. He just quietly shut down the Mariners whenever he faced them. Luckily for the M's, he didn't pitch in 2023 as he finished his career.

Joakim Soria: 45 G, 46.1 IP, 1.75 ERA, 0.91 WHIP, 21 BB, 21 H, 52 K, 21 SV

Soria loved the Mariners. Seriously, Of anyone who faced him in 10 or more games, the Mariners were far and away the worst. A .133/.238/.203 slash line shows how inept they were, especially when he walked as many hitters as he gave up hits. Just five doubles and two homers with a 43 OPS+ against him. I always enjoyed watching Soria pitch whenever he stepped to the mound at the end of the game... just not against the Mariners.
