The 28-year-old Arihara has garnered extensive experience in the NPB, where he has logged a 3.74 ERA with 6.7 K/9 and 2.1 BB/9 in 836 innings. At his best, Arihara put up a 2.46 ERA and recorded 8.8 K/9 against 2.2 BB/9 across 164 1/3 frames in 2019. Will Hoefer of Sports Info Solutions wrote in a scouting report after that season that “Arihara demonstrates strong command of his three best pitches–an above average four seamer, a plus change, and a slider that flashes plus,” and added that he could quickly turn into a mid-rotation starter in the majors.
Of course, before signing Arihara, any MLB team will first have to go through the posting system. Once Arihara is posted, he’ll be free to negotiate with all 30 big league teams. However, a major league club that signs Arihara will have to pay a 20 percent sum of the first $25MM to his NPB team. The MLB club would also have to surrender “17.5 percent of the next $25MM and 15 percent of any dollars spent thereafter,” as MLBTR’s Steve Adams previously explained.
