Organization Prospect Rankings
Track Record: McArthur was a three-year starter at Mississippi, but there was never a year where everything clicked for him. He never posted an ERA under 4.00, including a junior season with a 4.48 ERA and a 58-38 K-BB mark in 66 innings. The Phillies liked his combination of size and stuff, signing McArthur for $215,000 as a 12th-round pick in 2018, and he showed encouraging signs with strong performance in his pro debut.
Scouting Report: McArthur has an extra-large, 6-foot-7 frame, sitting in the 92-94 mph range and touching 96 with good extension that helps his fastball get on hitters quickly. His breaking ball flashes above-average with sharp, late biting action when it's on, though it's still inconsistent. He also throws a changeup that's a below-average pitch. Like a lot of extremely tall pitchers, McArthur struggled to control his delivery, leading to troubles with his command and control in college, although he was a solid-strike thrower in a small sample size with short-season Williamsport.
The Future: It might take some time for everything to click for McArthur, but there are some signs of him being another quality late-round pick for the Phillies. He's scheduled for low Class A Lakewood in 2019.
