Jeff Passan of ESPN was first to report the full trade.
Nastrini is the prize for Chicago in the deal. The Dodgers’ fourth-round pick in 2021 was part of this year’s prized Double-A Tulsa rotation, where Nastrini had a 4.03 ERA in 17 starts, plus 85 strikeouts and 37 walks in his 73⅔ innings.
He made one preseason top-100 prospects list, ranked 54th by Baseball Prospectus, though was not rated in BP’s top 60 in their midseason update of rankings. Jarrett Seidler, a senior prospect writer at Baseball Prospectus, chimed in:
Nastrini has backed up a decent amount this year, which is always a risk for breakout pitching prospects, and others in that system have passed him, but we're still seeing an emerging trend of very, very strong returns for rental pitchers— Jarrett Seidler (@jaseidler) July 28, 2023
Thompson struggled mightily with the Dodgers this season. He hit three home runs in his first game, but had just eight hits in 67 at-bats after that before landing on the injured list with a strained left oblique. Thompson in that stretch was hitless in 39 consecutive at-bats, the longest hitless skid by a Dodger in over a century.
Thompson is currently on the 60-day injured list and was on a rehab assignment with Triple-A Oklahoma City, for whom he hit four doubles and a home run in two games.
Because he’s on the 60-day injured list, Thompson did not count toward the Dodgers’ 40-man roster, so the team still needed corresponding roster moves to clear two spots for Lynn and Kelly. Those moves were Triple-A reliever Justin Bruihl and Double-A shortstop Eddys Leonard getting designated for assignment.
Leasure had a 3.09 ERA in 29 relief appearances for Double-A Tulsa this season, with 56 strikeouts (a 39.7-percent strikeout rate) and 16 walks in 35 innings. The Dodgers drafted him in the 14th round in 2021 out of the University of Tampa.
