LA Dodgers rookie Roki Sasaki has returned from exile, and he seems more focused than ever coming out of the pen. On Friday, Sasaki entered the game in the seventh inning against the Seattle Mariners. He faced AL MVP favorite Cal Raleigh in an electrifying duel.It took Sasaki three "nasty" splitters to strike out the Mariners catcher. The first pitch was in the middle of the zone, but the catcher let it go. Knowing that Raleigh will go for a swing on the next pitch, Sasaki intelligently placed his pitch low and just outside enough to bait the catcher into swinging for strike two. At this point, Sasaki knew he had the number of Raleigh as he threw a dirt ball and the catcher was fooled.
