36 Adam Liberatore RP

Liberatore underwent arthroscopic surgery on his left knee and faces a six-to-eight week recovery, J.P. Hoornstra of the Southern California News Group reports.

Liberatore is currently a free agent after being released by the Dodgers earlier this month. He expects to be fully recovered and with a new organization prior to spring training. Across 17 appearances with Los Angeles in 2018, he posted a 2.77 ERA and 1.38 WHIP.

Liberatore was designated for assignment by the Dodgers on Friday, Eric Stephen of True Blue LA reports.

Liberatore was cast off the 40-man roster in order to make room for the recently-acquired Ryan Madson, who was traded to the Dodgers from Washington on Friday. In 17 appearances with the big-league team this year, Liberatore has posted a 2.77 ERA and 1.38 WHIP but hasn't pitched for the Dodgers since June. He will be subject to waivers, but is set to remain with Triple-A Oklahoma City if he goes unclaimed.

Liberatore was optioned to Triple-A Oklahoma City on Saturday.

Liberatore was the casualty to make room for the return of Clayton Kershaw (back). In 13 innings for the Dodgers this season, he has a 2.77 ERA, though his 22.2 percent strikeout rate is mediocre and his 14.8 percent walk rate is poor, suggesting that he was getting fairly lucky.

Liberatore was recalled from Triple-A Oklahoma City on Friday.

Liberatore figures to be used in a relief role during his next stint in the big leagues. He's posted a 3.38 ERA and 1.25 WHIP with eight strikeouts across 12 appearances out of the bullpen.

Liberatore was optioned down to Triple-A Oklahoma City on Saturday, Andy McCullough of the Los Angeles Times reports.

Liberatore spent the last month at the major-league level, appearing in 12 games out of the Dodgers bullpen. During those outings, he logged a 3.38 ERA and 1.25 WHIP in eight innings of relief. In a corresponding move, Tony Cingrani (shoulder) was reinstated from the 10-day disabled list.
