Grabbed off the waiver wire late last season, Sadler actually appeared in seven games for the Mariners in 2020. You're forgiven for not remembering that; last year's bullpen was a revolving door of ephemeral failure. But unlike fellow forgotten 2020 relievers Bryan Shaw, Seth Frankoff, and Zac Grotz, Sadler (a) cracked ten innings pitched and (b) didn't suck. That's a low bar for success, but this is the Mariner bullpen, so we'll take it. Sadler posted a 4.50 ERA with Seattle, but a 3.29 FIP figure, suggesting his defense and/or subsequent relievers did him wrong. The veteran of five partial big-league seasons with the Pirates, Rays, Dodgers, and Cubs has been cruising through spring training, giving him a leg up on winning one of the spots in the ’21 bullpen.
At 30, the big right-hander is one of the oldest Mariners this season and has taken to the role of wise elder. “I don’t have a whole lot of service time," he said, "but I feel like an older veteran guy. And just to be able to pass some of the little knowledge that I’ve learned, playing with some of the guys that I’ve had a chance to play with, and just be there if they ever have any questions—or even just [be] a sounding board [for things like], ‘Hey, this is what I’m thinking. I just need to kind of talk through some things’—it’s really refreshing. I love to teach the game and I love to talk baseball.” Sadler's been through all the itinerant journey methods available in pro baseball—he's been drafted, released, a free agent, traded, traded again, designated for assignment, and claimed on waivers. He hopes the waiver claim sticks long term, as he now pitches for his home city. Sadler and his wife bought a home in the Snoqualmie Valley last May while he was a member of the Chicago Cubs. Said Sadler, “I think when we purchased [the house], from that point we were like, ‘Man, it would be really cool to play here. What an opportunity that would be.’ And, with baseball you just never know. Things can go unexpectedly—good or bad. Thankfully, the Lord blessed us and we’re able to stay at home and play for our hometown team now. That’s pretty cool. Pretty special.”
A starter until he was injured in 2015 (torn UCL), Sadler converted to relief after rehabbing from surgery (he did make one "start" for the Dodgers in 2019, but that was as an "opener"). His fastball/curveball/changeup repertoire relies on weak contact; as sinkerball pitcher, Sadler should benefit from the Mariners' solid infield defense this year when he's on his game. He lacks the velocity of some of his bullpen brethren, so if he leaves the ball up in the zone he's wont to get hammered.
