The highest unsigned pick from the 2016 Draft, Lodolo spurned the Pirates as a supplemental first-rounder (No. 41 overall) from a California high school. He immediately stepped into Texas Christian's rotation as a freshman but was somewhat of an enigma in his first two college seasons because his performances were more respectable than dominant. After showing more consistency and confidence this spring, he could be the first college pitcher drafted and beat out Lance Broadway (No. 15 overall in 2005) as the highest pick in Horned Frogs history.
Lodolo usually works at 90-94 mph and peaks at 96 with sink on his fastball, using his 6-foot-6 frame to deliver it on a steep downhill plane. He showed inconsistent feel for spinning a curveball in the past and is focusing instead on a tighter slider in the low 80s that has become a solid offering. He also sells his changeup well and it has good action at the plate, giving him three pitches that all can grade as plus at their best.
Lodolo has a long, lean body that could add more strength and an easy delivery. He's doing a better job of maintaining his three-quarters arm slot, resulting in improved control and command. He's also pitching with more confidence, attacking hitters and realizing the potential Pittsburgh saw in him three years ago

Manoah was a two-way player out of high school in the Miami area in 2016, but went undrafted and headed to West Virginia. The big right-hander worked more out of the bullpen than in the rotation over his first two seasons, but opened a lot of eyes as a starter in the Cape Cod League, leading the league in strikeouts. He's been that pitcher ever since, moving his way to close to the top of college arm options in this year's Draft.
A physical beast at 6-foot-6, 260-pounds, Manoah has always shown glimpses of solid power stuff, but without consistency or command of it. That's changed this spring as he has shown above-average control for most of his junior season. He's pitched with a fastball typically in the 94-97 mph range, missing a ton of bats thanks to good sink. His slider flashes plus at times and has been a more reliable weapon for him. He has a solid changeup, relying on it in the Cape Cod championship game, but he hasn't used it as much this spring.
Manoah has managed to keep his large frame in sync and has repeated his delivery in order to fill up the strike zone more effectively. Given that he doesn't have that many starts on his resume, he's a rare college pitcher with projection, something that should get him off the board in the first round, much earlier than his older brother Erik, currently a reliever in the Angels system, who was drafted by the Mets in the 13th round of the 2014 Draft.
