3 Players the Mariners gave up on too soon
Second Baseman Ketel Marte
Ketel Marte was a top prospect at the time he was traded along with Taijuan Walker to the Diamondbacks in a deal where the Mariners acquired Mitch Haniger, Jean Segura, and Zac Curtis. Ketel Marte struggled to find his power swing in Seattle slugging just .349 while hitting .267. Had the Mariners given him more time he could have developed into their future second baseman after Robinson Cano retired. However, the Mariners priorities were different back in 2016 and they needed outfield help. Marte’s best season for the D-Backs came in 2019 where he made the all-star game, hit .329, with 32 HR .981 OPS, and finished fourth in MVP voting. The Mariners could really use Marte now, especially given the struggles of finding a consistent second baseman post Robinson Cano. Since Cano was traded to the Mets the Mariners have played Dee Gordon, Shed Long, Dylan Moore, Abraham Toro, Adam Frazier, and now Kolten Wong at the position. Ketel Marte has split time between the outfield and second base, but he mostly plays second base, and would have been a better option than any of these other players just mentioned. In his time with the D-Backs Marte has hit .282, with a .824 OPS, 80 HR, and 290 RBI. The Mariners would certainly love to have his production at second base right now.
