MLB's fourth annual Draft Combine starts Tuesday at Phoenix's Chase Field with a five-hour broadcast of a pro-style workout on MLB Network from 1-6 p.m. ET. Position players will take part in batting practice and infield/outfield, and pitchers will throw bullpen sessions, interspersed with analysis of the prospects and interviews with players and team executives.
Here are the five-highest rated prospects on MLB Pipeline's Draft Top 200 who will participate in the workouts, plus five more to watch on Tuesday:
Kellon Lindsey, SS, Hardee HS, Wauchula, Fla. (No. 30)
Lindsey is arguably the fastest player in the high school class, flashing top-of-the-scale run times and an explosive first step. He may have played himself into the first round by improving his bat and his chances of staying at shortstop this spring.
Carter Johnson, SS, Oxford (Ala.) HS (No. 40)
As an Alabama prep shortstop with a big frame, Johnson draws comparisons to Gunnar Henderson. He's not quite as athletic as the Orioles' star, but Johnson is an advanced hitter with 20-homer upside who likely will wind up at second or third base.
Dasan Hill, LHP, Grapevine (Texas) HS (No. 50)
Hill's projectability dwarfed his present stuff on the showcase circuit last summer, but he has taken off since growing 3 inches and adding 15 pounds. His fastball has jumped to the low 90s while topping out at 96 mph, his low-80s slider with high spin rates has become a plus pitch, and his curveball and changeup also show promise.
Levi Sterling, RHP, Notre Dame HS, Sherman Oaks, Calif. (No. 51)
Part of a Notre Dame program that has spawned 1968 No. 1 overall choice Tim Foli, Hunter Greene, Jack McDowell and Giancarlo Stanton, Sterling stands out as one of the more polished and projectable arms in the high school class. His fastball reaches 94 mph, he exhibits good feel for spinning both a curveball and changeup, and he can miss bats with his changeup as well.
Chris Levonas, RHP, Christian Brothers Academy, Lincroft, N.J. (No. 54)
Part of a deep crop of New Jersey prep arms, Levonas reminds some scouts of Walker Buehler with his wiry 6-foot-1 build. He can run his fastball up to 97 mph, generates high spin rates on his slider and curveball and shows aptitude for throwing a changeup.
