"There are just some players that give you the heebie jeebies." Beautiful phrase. So, so true.
Man, we've had a lot of those, haven't we? Guys that make you want to crawl out of your skin rather than watch them play. My fandom was born in the mid aughts, but I can still draw up a long list of Mariners who were viscerally unpleasant to watch. Miguel Batista, Carlos Silva, Horacio Ramirez, Rob Johnson, and Ronny Cedeno spring to mind. I will never get over how much I hated watching Cedeno swing through high fastballs, or Johnson drop chase Felix’s pitches to the backstop, or Miguel Batista throw literally anything.
At least it's been a while since any Mariner made me feel downright revulsion. I sincerely pity anyone who feels like that about Gallardo. The vitriol against him makes a lot of sense in that context.
