Santana is far from perfect. He's struck out 135 times this season, which is the most in Major League Baseball. He also has 12 errors on the season, nine of which came in left field (three in right field).
His flaws should bring the Mariners' asking price down and his strengths are exactly what the Indians need. Santana is a plug-and-play right-handed power bat who can be the designated hitter for the rest of 2019 and beyond.
Manager Terry Francona has used multiple players in the clean-up spot this year. Santana can fill that void and do so without impacting the Indians defensively.
They have three players capable of playing the corner outfield positions at a high level with Tyler Naquin, Jordan Luplow and Greg Allen. Santana addresses a big need and does so without mortgaging the future.
President Chris Antonetti shouldn't have to give up multiple top prospects to land a flawed player like Santana. This is the type of 'win-now, while also preparing for the future' move that the Indians are hoping to find.
