Brady Singer was a sandwich-round pick in 2015, but did not agree to terms with the Toronto Blue Jays, so he ended up at the University of Florida. There, he had a breakout freshman year that established him as a likely first-round pick for 2018. I saw Singer pitch last season at Vanderbilt, and his velocity was sitting 90-91 mph with the same high-effort arm action and low slot that he showed as a freshman. He was effective against right-handed batters but struggled against lefties and generally lacked command of his fastball. He threw on Friday night for the Gators at the University of Miami, and while he touched 95 mph early, it was more of the same for the right-hander.

Singer was throwing 90-95 over his five innings, mostly 90-92 after a few high velocities in a 28-pitch first inning, while also throwing both a curveball and slider, and with just two changeups in the outing. The fastball is straight and Miami’s hitters seemed to see it very well, especially the lefties, so by the third inning Singer was pitching primarily with his two breaking balls. The curveball is 75-80 mph, a solid average with a few better than that, while the 85-86 mph slider was sharper as a right-on-right weapon. He tries to back door his breaking stuff to lefties, but doesn’t have the bite or command to pull it off consistently, and when he went to the fastball instead, he got hit.

Singer’s delivery is unlike that of any MLB starter I can think of. It has more in common with Chicago White Sox prospect Carson Fulmer’s, and Fulmer has struggled to stay a starter in pro ball in large part because of his poor command. Singer comes from below low three-quarters, and while his arm is quick, he rushes his delivery, moving right off the rubber, without using his legs much at all to generate velocity. That’s an arm action that is hard to repeat, and it probably increases his risk of arm trouble.

I had Singer No. 22 on my preseason rankings, which might be high given what he showed on Friday night. If he’s pitching with just average velocity and nothing else remarkable about the fastball, lacking great spin or much deception, it’s hard to profile him as more than a back-end starter, even with a track record of performance. He’s famous, though, and sometimes that carries the day in the draft room anyway.

• Jackson Kowar, a more traditionally built right-hander (and not in the sense that Mma Ramotswe might use the term), pitched on Saturday night. He showed a much better arsenal than Singer did along with a delivery that, while not ideal, looks more starter-like.

Kowar’s fastball sat 92-95 mph for his entire six-inning outing, and it had a little more life and seemed to burst in on hitters at the last second, causing a lot of highly defensive swings from Miami hitters. He paired it with an easy plus changeup at 82-84 mph that he used against both right- and left-handed batters, with good deception and heavy action as it reached the plate. His curveball is his worst pitch, although he threw some that were grade 55s and some that were below. It’s a 75-78 mph pitch with good two-plane break when he hits it, but the pitch backs up on him too often to make it a viable second pitch, leaving it more a weapon to spin away from right-handers so he can follow up with something on the inner half.

Kowar very much looks the part of a starter, with a tall, lean but projectable frame, with broad shoulders and more athleticism on the mound. He strides a little short to the plate and there’s effort to the delivery, including a modest head-whack at release, although because he (like Singer) starts on the extreme first-base side of the rubber, he doesn’t come across his body. His control is fringy and he still has below-average command, meaning he’s not the type of college pitcher who will race to the majors in a year like Michael Wacha did. Kowar has at least mid-rotation upside, probably more if the curveball becomes consistent or the team that drafts him gives him a slider to take advantage of that arm speed. He’s still a top-half-of-the-first-round talent, with a chance to go top 10 with a good spring.

• The Gators just keep finding pitchers. Their Sunday starter, Tyler Dyson, is a potential top-10 pick in 2019, and two freshmen pitched in relief on Friday and Saturday, both looking like potential first-rounders. Jack Leftwich was throwing 93-96 mph in relief of Kowar with a power curveball in the low 80s, mostly working with his fastball, from a three-quarters arm slot to go with a great pitcher’s build. Tommy Mace was more in the 89-90 range, but he moved the ball around well and still has some projection. Both look like starters, perhaps taking over for Singer and Kowar in the weekend rotation next spring.

• J.J. Schwarz had such a miserable junior year that I called him “undraftable” on ESPNU’s College Baseball Tonight last April, which turned out to be correct, as he fell to the 38th round -- there are only 40 rounds in total -- and he returned to Florida for his senior year. He’s catching again, and handled Singer and Kowar reasonably well (I doubt either is easy to catch), while also destroying a home run on Friday night with a looser swing than he had last spring. I doubt he’s much of a framer given how he catches balls moving out of the zone, but if he’s just good enough to be a backup in the majors, he has the power to be a pretty good bench piece.

• Miami’s Saturday starter, right-hander Greg Veliz, is a draft-eligible sophomore and could go in the top five rounds, but he’s held back by atrocious control. He was throwing 89-92 against Florida, with one 93 mph fastball that got away from him and forced in a run, and he showed a potentially average slider mostly thrown at 83-85. The Canes also have a junior reliever, right-hander Andrew Cabezas, who should be a Day 2 pick. His fastball is 89-93 mph with some two-seam life and he has a fringy curveball, but he’s a pure reliever at just 5-foot-10 with a long arm swing.
