Past Fantasy Outlooks
2022
2021
Wendelken's performance took a dip with Oakland last season and he was designated for assignment in mid-August. However, Arizona recognized his solid body of work since 2018 and claimed him off waivers. The 28-year-old earned two wins, four holds and the first two saves of his career across 20 appearances with the Diamondbacks, but he wasn't overly impressive, posting a 4.34 ERA, 6.3 K/9 and 4.3 BB/9 across 18.2 innings. Despite a subpar 2021, he remains one of the most experienced relievers in Arizona's bullpen after the team signed veteran Mark Melancon for their closer role. Wendelken could pick up a save chance or two when Melancon is unavailable, but he's more likely to be an asset for holds after posting an ERA under the 3.60 mark in three straight campaigns between 2018 and 2020.
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.

Latest Fantasy Rumors
Taking over as closer?
PArizona Diamondbacks  
September 23, 2021
Wendelken recorded his second save of the year Thursday and could be taking over the closer role from veteran Tyler Clippard in the season's final weeks.
ANALYSIS
Clippard struggled Wednesday, allowing three runs in an inning of work, and the Diamondbacks turned to Wendelken for their next save opportunity. With the team sitting at 49-104, it wouldn't be surprising to see the 28-year-old Wendelken continue to see work over the 36-year-old Clippard.
