The Los Angeles Dodgers on Thursday recalled left-handed pitcher Julio Urias from Triple-A Oklahoma City and optioned left-handed reliever Adam Liberatore back to OKC.

Urías, 20, will make his 2017 debut with a start against the Giants in the series finale after last pitching for Oklahoma City on April 21 against Nashville (Athletics), allowing just two hits in 5-2/3 scoreless innings and striking out six against three walks on 93 pitches. In three starts with the Oklahoma City Dodgers this season, he posted a 1.93 ERA (3 ER/14.0 IP), while holding batters to a .170 average (8-for-47) and striking out 15 in 14.0 innings.

The Culiacan, Mexico, native saw his first big league action last season in four stints with the Dodgers, going 5-2 with a 3.39 ERA (29 ER/77.0 IP) and struck out 81 batters against 31 walks. In his Major League debut last season on May 26, 2016, Urías became the youngest Dodger starting pitcher at 19 years, 228 days, since Dick Calmus, who took the mound at Dodger Stadium on Aug. 23, 1963 at 19 years, 228 days.

Liberatore, 29, last pitched on Monday against the Giants, allowing one run on one hit in 1/3 innings of relief in his lone appearance for the Dodgers since being recalled on Sunday from Oklahoma City. Before his promotion, the southpaw tossed scoreless relief in five of six games at Triple-A, going 0-1 with a 1.59 ERA and limiting opposing hitters to a .238 batting average with a 0.88 WHIP.

The move presumably also bumps lefty Alex Wood back to the bullpen. Wood threw six scoreless frames against the Giants on Wednesday evening, surrendering only two base runners. He did not figure into the decision.
