These 10 Pitchers have owned Mariners hitters during their careers

Mike Witt: 28 GS (30 G), 210.2 IP, 2.69 ERA, 1.18 WHIP, 13 HR, 12 CG, 14-7 Record

Not gonna lie. No idea who this is. He only threw 11 games between 91-93, which is before my recollection being born in the late 80s. The Mariners struggled more than any other team that Witt ever faced, as he ate up innings against them and kept them off the board at the same time. 13 HR in 210 innings can do that to a team.

Zack Greinke: 18 G, 107.1 IP, 2.35 ERA, 0.98 WHIP, 87 H, 93 K, 8-2 Record

Greinke is one of the oddest and coolest dudes in baseball, and he has climbed my list of guys that I'm a fan of. People forget that Greinke was a monster on the mound for a long time, and graces one of the coolest T-shirts I've ever seen as well. If he throws a full season next year, he will officially have been in the majors longer than not, as it will be his 21st season. It's not just the Ms he dominated, as they still rank 7th/4th/3rd worst in BA/OBP/SLG against the wizard.

Tommy John: 22 GS, 134 IP, 2.28 ERA, 1.06 WHIP, 21 BB, 36 K, 13-4 Record

Yup. Tommy John. The guy who has the surgery named after him. He was around forever, making his debut at 20 on 09/06/1963 and last throwing on 05/25/1989. That's wild. He has the 8th most starts ever, plus 60 relief appearances. The Mariners hit just 7 homers against him, constantly finding weak contact against the ageless wonder.

Pedro Martinez: 14 G, 103 IP, 1.57 ERA, 0.85 WHIP, 63 H, 137 K, 2 CG, 13-1 Record

You had to know this was coming, right? Pedro dominated a lot of teams in his career, but it seemed like he had a personal vendetta against the Mariners. When you combine the K's, record, and slash line, it's not hard to argue they were his favorite opponent. Just 63 hits in 103 IP, and in fact the Mariners scored more than one run just 3 times in his first 12 starts against them, with an ERA of 1.00 through 90 innings. Joy bloomed in his final decision against the Mariners, as they beat the then-Mets Martinez 4-1 in June 2005 thanks to some bloop hits and a stellar outing from Ryan Franklin.
