Leclerc failed to record an out and was charged with the loss in Saturday's 7-4 loss to the Angels in 10 innings. He walked all three batters he faced and was charged with three earned runs.
A promising first half allowed Leclerc to emerge as one of the top closers in waiting after Matt Bush was pulled from the role in late June, but the rookie's implosion since the All-Star break has dimmed any chance he has of displacing Alex Claudio as the team's ninth-inning man. Over 18 appearances in the second half, Leclerc has submitted a 5.87 ERA and 13:21 K:BB in 15.1 innings.
