Roki Sasaki allowed two runs in 5 1/3 innings and fanned seven in a win over the Mariners on Thursday.

Sasaki’s splitter did most of the work tonight. He threw it 37 times in the 90-pitch outing and got 10 whiffs and four strikeouts with it. Meanwhile, it produced no hits or hard-hit balls the seven times it was put into play. Sasaki remains rather difficult to trust, but this makes four solid outings in a row, and with arguably baseball’s best team backing him, he’s not a bad play in shallow leagues at the moment. He’ll likely pitch in Chicago against the Cubs next Wednesday, though it’s possible he could be pushed to Friday in Arizona instead.
