When the trade was announced Dec. 2, the Dodgers received Knebel for a player to be named or cash. The player heading to Milwaukee was identified as Crawford on Friday.
Crawford, 23, went 7-4 with a 2.81 ERA and 134 strikeouts in 121 2/3 innings while splitting the 2019 season between the Dodgers' Class A affiliate in Rancho Cucamonga and Double-A team in Tulsa. He made 21 starts that year.
Milwaukee president of baseball operations David Stearns said Crawford has some similarities to Brewers left-hander Brent Suter in that both rely on deception to overcome a relative lack of velocity.
"He's left-handed, he throws in the high 80s, so you're going to get some of that," Stearns said. "He relies on deception and changing his offerings. There is some of that. I think they probably get to their deception a little bit differently. Obviously Brent works incredibly fast and has used that to his advantage over the years. Leo, when you watch him kind of with his actual pitching mechanics, with his pitching motion, he'll vary timing in order to disrupt the hitters a little bit. But they are two left-handed pitchers who've had success despite not having overpowering fastballs."
There was no minor league season in 2020. Stearns said he believes Crawford spent most of the 2020 season in Nicaragua and currently is pitching in winter ball there. Crawford was born in Nicaragua.
Knebel, 29, made the National League All-Star team in 2017 and was a key part of Milwaukee's bullpen before missing the entire 2019 season with a torn ulnar collateral ligament in his pitching elbow. The right-hander posted a 6.08 ERA in 15 games last season.
