Sasaki Roki's first 3A rehab game was a struggle.

The Dodgers' Japanese rookie right-hander Sasaki Roki returned to the field today, marking his first appearance since May 9 in U.S. time, as he recovers from a right shoulder injury.

In his debut with the 3A Oklahoma City team, Sasaki used 41 pitches to record 6 outs and failed to retire two batters he faced in the third inning. He gave up 6 hits, issued 1 walk, did not strike out any batters, and ultimately allowed 3 runs.

Sasaki Roki's fastball averaged 93.6 mph, reaching a top speed of 95.7 mph. Last week, he maintained a velocity of 96-97 mph in a three-inning simulated game.

The Dodgers initially hoped that Sasaki Roki could pitch through three innings. Once he can extend his pitching to five innings or 75 pitches, he could return to the Dodgers in late August or early September.

As a highly sought-after international signing, Sasaki Roki created quite a stir when he joined the Dodgers, but he is still in the process of developing. During his first taste of the majors, he posted a 4.72 ERA over eight starts and was placed on the injured list on May 13.

During his recovery on the sidelines, Sasaki Roki focused on adjusting his pitching mechanics and practiced the two-seam fastball to enhance his three-pitch repertoire (although he did not throw this pitch today). Dodgers manager Dave Roberts also emphasized the importance of building confidence for Sasaki during his rehab.

Currently, the pitching rotation for this major league team is quite healthy, with Tyler Glasnow and Blake Snell returning from the injured list. Nevertheless, any contribution from Sasaki Roki would provide additional security, especially as the Dodgers suddenly chase the Padres in the NL West.

Sasaki Roki was not the only Dodgers pitcher to start a rehab game today. Michael Kopech, recovering from right knee surgery, allowed 3 runs in 0.2 innings of work due to two hits and two walks, including a single and two wild pitches that resulted in scoring.
