FanDuel Price: $3,000
After some time off, Welington Castillo returned to the lineup with a bang on Monday, going 4-for-5 with two RBI's.
He has had a decent year from the dish, slashing .264/.316/.441 with a .321 wOBA, but his work against left-handed pitching is what really makes him a great option today. He's slashing .326/.376/.651 with a huge .426 wOBA against lefties on the year. With a career .374 wOBA and 38.8% hard-hit rate against lefties, this season's success is no fluke.
As an added bonus, he has a favorable matchup against Jon Niese, a lefty whose 4.61 SIERA marks his third time in the last four seasons that he has posted a SIERA above 4.00.
