Yankees are 20-6 now against Lefty Starters, you better be a above average Lefty, (like Sale), to beat them. They don't hit them for average, they just hit HRS. If we face them in Post-Season, this better be thought out, to break up putting 3 Lefties in a row.
Edit: Sanchez is struggling and yet he has a .264 average against Left Handed Starters this year, with 6 HRS. They like Lefties.
