Dodgers' Roki Sasaki 'open' to pitching in relief

Roki Sasaki has been on a rehab assignment with Triple-A Oklahoma City for 31 days now, meaning that he would normally need to be activated from the injured list or pulled off his rehab assignment today. That’s not the case in this instance, however, as manager Dave Roberts told reporters (including Fabian Ardaya) on Friday that Sasaki dealt with “a calf situation” during his rehab that extended the time he could be allowed to spend in Triple-A. He’ll make at least one more start in the minors, per Roberts, at which point it’s possible he’ll move back into pitching in MLB games.

Sasaki, 23, was perhaps the single most coveted free agent available last offseason after he made the decision to be posted for MLB clubs early. Sasaki’s decision meant that clubs couldn’t spend more than the sum of their international bonus pool money in order to lure the right-hander into signing a contract with them, meaning that virtually every team in baseball got involved in the Sasaki sweepstakes. The Dodgers ultimately came out on a top, and while many at the time thought they had just locked up an ace for pennies on the dollar Sasaki has struggled in his first season stateside.

The right-hander posted a 4.72 ERA in eight starts for the Dodgers while walking (22) nearly as many batters as he struck out (24) before being placed on the injured list with a shoulder impingement back in May. He’s been sidelined ever since, and after he made his first rehab start at Triple-A on August 14 he’s not shown many signs of improvement. Those 18 2/3 innings of work with Oklahoma City have seen him pitch to a 6.75 ERA. While his 13.6% walk rate and 18.2% walk rate are both marginal improvements over his numbers in the big leagues, they’re still far below par in terms of command and not close to what one would expect from someone with Sasaki’s electric stuff.

Talented as the youngster is, it’s fair to wonder at this point whether the Dodgers would really be best served having Sasaki start big league games in the middle of a pennant race that figures to go down to the wire. Roberts didn’t specifically state what role Sasaki would take up upon returning to the big league club, but he did note that his “impression” is that Sasaki would be open to pitching in relief for the team if that’s what the club requires. With some combination of Blake Snell, Tyler Glasnow, Shohei Ohtani, and Yoshinobu Yamamoto exceedingly likely to make up the Dodgers’ postseason rotation anyway, perhaps Sasaki could benefit from moving to the bullpen and focusing on maximizing his stuff in shorter bursts.

If Sasaki can prove to be effective in a relief role, that could be a huge relief for the Dodgers headed into the postseason given the struggles key relief arms like Tanner Scott, Kirby Yates, and even Blake Treinen have faced this year. With those late-inning veterans scuffling, the Dodgers already seem likely to rely more on young, talented hurlers like Alex Vesia and Jack Dreyer in high leverage situations moving forward. It would be a massive boon for the Dodgers if Sasaki can be part of that mix headed into the playoffs.
