3. Felix Hernandez – 2010

Very rarely does a pitcher with a record one game over .500 win the Cy Young Award. That’s how outstanding Hernandez was in 2010. He was about the only good thing Seattle’s pitching staff had that year; the team won only 61 games. King Felix was also dependable, once again leading the league in starts.

One side note, Hernandez made the All-Star team six out of seven years between 2009-2015. This was the year he wasn’t selected.

  • 13-12 record.
  • 1st – 34 starts.
  • 1st – 249.2 innings pitched.
  • 1st – 1001 batters faced.
  • 1st – 2.27 ERA.
  • 1st – 7.0 H/9.
  • 2010 Cy Young Winner.

2. Randy Johnson – 1997

This was the first year Seattle hit 90 wins. As well as the first time they broke the three million fan mark. Undoubtedly many came to see Randy Johnson pitch. He lost one home start all season. Johnson won 20 games for the first time, and his 2.28 ERA was the best of his career. Because he missed a few starts, the Big Unit only had 291 strikeouts and finished second (one behind Roger Clemens.

  • Record 20-4, 2.28 ERA (2nd in both wins and ERA).
  • 1st – 6.2 H/9.
  • 1st – 12.3 K/9.
  • 1st – .833 win/loss percentage.
  • 2nd in Cy Young voting.

1. Randy Johnson – 1995

This was the Seattle Mariners first-ever playoff season, so it’s not much of a surprise the team’s best pitcher is ranked here. Johnson had one of his best seasons in 1995, posting an 18-2 record. Both of his losses came when the Seattle Mariners scored two or fewer runs.

Most importantly, he won his first of five Cy Young Awards. Johnson carried the pitching staff with a 2.48 ERA. None of the other M’s starters got under 4.50. The Big Unit was money every time he took the hill.

  • Record 18-2 (2nd wins).
  • 1st – 2.48 ERA
  • 1st – .900 winning percentage.
  • 1st – 294 strikeouts.
  • 1st – 1.045 WHIP
  • 1st – 6.7 H/9.
  • 1st – 0.5 HR/9.
  • 1st – 12.3 K/9.
  • 1st – 4.53 (K/BB).
  • 1995 Cy Young Winner.

The Seattle Mariners have some good young pitchers in their organization. Who will be the next one to make this list.
