Average fastball velocity (min. 10 pitches)
Blue Jays RHP Nate Pearson, 98.4 mph -- Was there any doubt? MLB Pipeline's No. 10 overall prospect is known to pump plenty of gas, and that didn't change in his March 1 start against the Pirates. Pearson threw heaters on 21 of his 28 pitches and touched as high as 99.9 on the Statcast radar gun. Including last year's time in the Majors, that would be tied for his sixth-hardest-thrown pitch measured by Statcast so far. Unfortunately, it will be a while longer until we see the 6-foot-6 right-hander pumping gas again. He suffered a Grade 1 strain of his right groin in that one Grapefruit League appearance, and the Blue Jays did not have an immediate timetable for the righty's return. He extended his long-toss program to 120 feet this week, so there is optimism on that front. Getting Pearson's 80-grade heater in the rotation would be a big piece of helping Toronto track down New York and Tampa Bay in the AL East. (Speaking of the AL East, Yankees right-hander Albert Abreu has the highest velocity on a single fastball so far this spring at 100.4 mph.)

Top Prospects: Nate Pearson
Average fastball and curveball spin rates (min. 10 pitches)
Blue Jays RHP Joey Murray -- Yes, Murray is tops in both categories, making the 24-year-old right-hander someone worth following in the weeks leading up to Opening Day. Murray's fastball has averaged 2,706 rpm (fourth-best this spring) while his curve is tops among all Spring Training pitchers at 3,105 rpm. The sample remains small; Murray has thrown only 24 fastballs and 10 curves, but this lines up with previous reports on the Toronto hurler's stuff. The 2018 eighth-rounder gets great extension from his 6-foot-2 frame, and the spin on the fastball makes it play up significantly despite averaging only 90.8 mph this spring because it's so difficult for hitters to pick up. Add in a high-spin curve, and it's not hard to see how Murray fanned 169 in 137 1/3 innings across two Class A levels and Double-A in 2019. The Jays want to keep him as a starter, but these two pitches alone could make him useful out of the Major League bullpen quickly.
Catcher arm strength
Blue Jays C Gabriel Moreno, 81.1 mph -- Make it a trio of Toronto prospects that Statcast has already shined on in 2021. There has been plenty of attention paid to Blue Jays catching prospect Alejandro Kirk coming off his Major League stint last season, but Moreno has tried to make the most of his own opportunities in Spring Training looks. One such chance came Sunday when Tigers outfielder JaCoby Jones attempted to steal second base. Moreno's pop time of 2.01 was on the average side, but his throw that measured at 81.1 mph was better. (Jones still successfully swiped second.) That one toss was equal to the Major League-best average catcher arm strength put up by Brewers backstop Manny Piña last season. Moreno, who is entering only his age-21 season, draws strong reviews for his athleticism that can help with his work behind the plate, and it was on display here.
