Wittgren elected free agency after being outrighted to Triple-A Columbus by Cleveland on Friday, Mandy Bell of MLB.com reports.
Wittgren began the 2021 campaign as a potential closing option for Cleveland, but he quickly fell out of favor for high-leverage opportunities and posted a 5.05 ERA, 1.25 WHIP and 61:17 K:BB over 62.1 innings. The right-hander had a 2.97 ERA in 112 appearances across the previous three seasons, so he should be able to latch on somewhere during the offseason.
