J.B. Wendelken

The A's have produced some of the top fantasy closers in recent seasons and it may now be Wendelken's time to shine in the ninth. He is not a flamethrower, but Wendelken sits 94-95 mph on average with his four-seamer, so he's no soft-tosser either. It was his slider -- which gets lumped in with his changeup on some sites -- that was next-level in 2020 as he allowed a silly .104 wOBA on the pitch, per Statcast (112 thrown). For his career, Wendelken has allowed 10 barrels among 235 batted-ball events, and he has posted an xBA below .190 in each of the past three seasons. He flipped the script and became more of a groundball pitcher last season, which is nice, although he had no homer issues to speak of anyway even when he was allowing more balls in the air. Oakland has its sights set high and brought in Trevor Rosenthal to be the successor to Liam Hendriks, so Wendelken will have to continue to prove himself in the middle innings.
