Moves to IL with finger injury

Finger
May 9, 2021
The Rangers placed Arihara on the 10-day injured list Sunday due to a right middle finger injury, Sam Blum of The Dallas Morning News reports.
ANALYSIS
Arihara had experienced discomfort in the finger following his April 30 outing against the Red Sox, resulting in the Rangers skipping him for one turn through the rotation. The rookie demonstrated enough progress to gain clearance to start Saturday against the Mariners, but he wasn't in top form, as he was shelled for five runs on six hits and three walks over 3.2 innings. Manager Chris Woodward noted that Arihara disclosed following the poor start that the sore finger was still affecting him, so the Rangers will shut him down for the next week and a half with the hope that extended rest resolves the issue. Hyeon-Jong Yang, Kolby Allard and Wes Benjamin are the most likely candidates to step in as the Rangers' fifth starter while Arihara is on the shelf.

2020 Fantasy Outlook
Arihara is younger at age 27 than most players moving from Japan to MLB, but he's also not as established. He had a career season in 2019 going 15-8 with a 2.46 ERA and 8.8 K/9 for Nippon Ham. He features a low-90s fastball, but has four off-speed pitches (slider, changeup, splitter, cutter), with his changeup and splitter seen as plus offerings. His lower velocity may limit his upside in the majors, but he could get a chance to win a spot in a MLB rotation. He's asked his NPB team to post him to MLB, but it's not clear if the the Nippon Ham will follow through with his request for the 2020 season.
