A hearty welcome to . We Jarren Duran Jersey discu sed his case for promotion last week. Though he had seven hits in 10 plate appearances over the weekend, this promotion is all about his glove. Anything he adds with his bat is gravy. Well cover more recent and potential call-ups in todays edition of Big Hype Prospects. Five Big Hype Prospects , 19, SS, BAL (AAA) (A/A+/AA) 520 PA, 10 HR, 23 SB, .326/.444/.504 As I noted last week, Hollidays promotion to Triple-A means we finally get acce s to public exit velocities. Those go a long way to influencing when a prospect earns his first promotion to the Majors. His 89.6 mph average and 103.7 mph max EVs in 30 plate appearances arent particularly impre sive. They suggest the Orioles are better off with their existing middle infielders. Overall, hes hitting just .200/.333/.280 in Triple-A. One silver lining, hes posted more walks than strikeouts. Of course, were also talking about a tiny sample. That should go without saying. Before anyone frets about his lack of pop in 30 plate appearances, an acquaintance was nice enough to pa s along his Double-A data. His 109.7 mph max EV is excellent for a 19-year-old at any level. The chart I received doesnt list an average, but its visually somewhere between 90 and 93 mph also excellent. , 20, 3B/SS, TBR (AA) (A+/AA) 486 PA, 30 HR, 5 SB, .330/.391/.604 left the Rays in a tough spot, relying on the soft-hitting and to handle shortstop. Caminero represents a go-for-power alternative. Though he mostly plays third base these days, that decision was at least partly in deference to his expected future role. Caminero might not be much of a downgrade defensively Walls isnt exactly a superstar defender. Caminero is still athletic enough to cover shortstop at present. Since August 25, he batted .354/.436/.917 with eight home runs in 55 plate appearances. , 21, OF, TEX (MLB) (AA/AAA) 513 PA, 12 HR, 25 SB, .288/.413/.450 An injury to opened the door for Carter to join the Rangers roster. He was reportedly already under consideration, the injury merely turned when to now. Oft-compared to (theyre eerily similar), Carter plays within himself. Not all scouts appreciate this the current meta is all about chasing extreme outcomes. In particular, he looks like he should be able to hit for power, but he maximizes for on base percentage rather than slugging. Thats just the first of many commonalities with Nimmo. The Rangers have a reputation for forcing their prospects to produce pulled, fly ball contact. That Carter reached the Majors despite eschewing organizational preferences suggests theres an interesting behind-the-scenes tale to tell. , 21, SS, ARI (MLB) (AA/AAA) 490 PA, 20 HR, 36 SB, .278/.378/.496 Questions about Lawlars hit tool mostly fly under the radar thanks to heady results and plus shortstop defense. Hes considered one of the best athletes in the sport. The most optimistic scouts consider him a 70 overall on the 20-80 scale. Aside from consistency of contact, Lawlar offers the total package. Hes an above-average runner, fields and throws well, and already flashes 30 homer upside as part of a discipline-forward approach. Though hes not as extreme as , theres a chance Lawlars early outcomes follow a similar track. , 25, SP, OAK (MLB) 23.1 IP, 9.64 K/9, 2.70 BB/9, 3.09 ERA Miller returned from injury on September 6. Hes scheduled to make his first start since April on Monday. A hard-thrower with a limited repertoire and a long injury history, Miller has rare potential to overpower Major League hitters. Developed as a starter, evaluators remain split on his ultimate role. A proactive conversion to relief could help to lengthen his career or at least improve his effectivene s. As a starter, the range of outcomes looks something like to with a real chance that hes usually too hurt to contribute. Three More , CHC (19) : I knew there was a fifth Jackson I forgot last week. Ferris is the also-ran among the prominent Jacksons in baseball, but he still tracks as a potential Top 100 prospect within the coming years. The southpaw has a repertoire of four average or better offerings backed by presently poor command. Hes posted a 3.38 ERA with 12.38 K/9, 5.30 BB/9, and a 53.4 percent ground ball rate in Low-A. (22) : The Twins are relatively deep in the middle infield or else Lee would be on the shortlist for a promotion. Hes a well-rounded player who lacks standout tools or notable shortcomings. Hes posted above-MLB-average EVs in Triple-A. , NYM (21) : Since joining the Mets organization, Acuna has cut his swinging strike rate nearly in half. He also cut his power in half. The net result is a sharp decline in offensive value. For now, this has the look of a step back for (hopefully) two steps forward. Did I mi s a detail or nuance?
