No. 2 – Robinson Cano
To be honest, I grappled with who should be the Mariners best second baseman ever between my second pick and first. There is no doubt that athletically speaking, Robinson Cano is the best. He has had a career of huge production and numbers that are worthy of the baseball Hall of Fame.
But the issues with Cano cannot go without mention either. Seattle signed Cano to a massive 10-year and $240 million contract in 2013. This was a mistake. There was no way that with the players around Cano that Seattle was going to contend while he was getting paid that much. Seattle didn’t make the playoffs during the time Cano was a Mariner.
Cano also was suspended for 80 games in 2018 after testing positive for a diuretic. (He has since been suspended for the entire 2021 season for testing positive for the performance-enhancing drug stanozolol.) So in the grand scheme of things, Cano was not worth the money Seattle paid him.
That said, compared to other historical Mariners second basemen, Cano put up very good numbers with 107 HRs and 411 RBIs in five years with the team. He batted .297 and made three All-Star teams. Cano also had an on-base percentage of .350 or better in three seasons.
