Signed as a high school draftee taken in the 26th round of the 2015 Draft from Maryland, Newsome had largely flown under the radar in the early stages of his pro career as an undersized right-hander with a really good feel for pitching. A slight uptick in his stuff helped him break out a bit in 2019, earning a California League All-Star nod and a promotion to Double-A. Still, the Mariners didn’t protect Newsome from the Rule 5 Draft last December and he wasn’t selected.
Newsome can throw four pitches for strikes, and that’s an understatement. His fastball is now in the 90-94 mph range, which is average in terms of velocity, but he can spot it on a dime and it has good riding life. His slider is his best secondary pitch and he manipulates it well, adding shape to it when he wants to. His curve is fringy, but he commands it well and while his changeup isn’t anything special, there is some arm-side run and late bottom to it, and he plays it off of his fastball very well.
The strike-throwing for Newsome is exceptional, as he carries a phenomenal 1.1 BB/9 rate for his career into the 2020 season. He’s willing to throw any of his pitches at any point in the count and does a nice job keeping hitters off-balance, so while his ceiling is limited to that of a back-end starter, there’s more confidence that he could get there, or at least fill a swingman role in the big leagues soon.
