8/7/26 : Minor League Radar Watch

Today is the 44th wedding anniversary for my wife Barb and I. Over the past couple of months we’ve been thru a lot of agony experiencing the loss of our oldest son - today is yet another reminder to hug and cherish those you love each and every moment as time is fleeting. I love my wife with all my heart, it’s the privilege of my life to be her husband - just sayin. Now here’s something else I truly enjoy - writing about Phillies player development 🤓.

The trade deadline has come and gone and four Phillies minor leaguers were traded to acquire big league talent. The regular season ends for the DSL Phillies on 8/18/26, Clearwater and Jersey Shore on 9/6/26, Reading on 9/13/26 and Lehigh Valley on 9/20/26. Clearwater has already qualified for the playoffs by winning the first half title in the Florida State League, the DSL Phillies are currently in first place in the East Division and Reading currently holds down first place in the second half Eastern League NorthEast division playoff race.

Here’s a look at some fellas popping up on the radar ya all should be taking notice of going down the stretch.

Lehigh Valley :

RHP Alex McFarlane - the 25 year old fireballer regularly pops the speed gun at 100 to 101 mph and has been recognized with two minor league system “Pitcher of the Month” awards this season (May & July). After making his major league debut on 7/22 he was optioned to Lehigh Valley where in three appearances (3.1 IP) the opposing hitters have just a .091 batting average on only one hit, he’s struck out 6 and walked 2 - has a 58% strike ratio in 62 pitches thrown. Alex was dominant at Reading (2.06 ERA - 35 IP, 47 K’s) while there. In my humble opinion he’s ready to help the big club right now - has the capability to pitch a couple innings per appearance.

RHP Michael Mercado - another high octane bullpen arm who’s thrown the ball very well for most of the season - he had three stumbles in May that pushed his season ERA to 3.63 in 44.2 IP (31 appearances) - in the other 28 appearances (41.2 IP) his ERA is a strong 2.16. Michael is throwing strikes at a 59% rate - since 6/2 he’s made 16 appearances covering 24 IP with 30 strikeouts and 10 walks - in 14 of those outings he walked one or less batters, had a hiccup on 7/10 when he walked four. He’s pushing a four seamer in the 95 to 97 mph range along with a cutter, splitter and curve. No longer on the 40 man roster this 27 year old maybe should be once again - if he throws the ball like he has the past couple of months he could certainly help in the show.

Andrew Painter’s return to the big leagues was due to a focused effort to identify and correct issues in his mechanics and pitch mix. Credit is due to big league coaches Caleb Cotham, Mark Lowy, minor league pitching pitching coordinators Casey Weathers and Travis Hergert along with Lehigh Valley pitching coaches Phil Cundari and David Howell for identifying a collaborative plan of action, along with Andy himself for being coachable and putting the plan in motion. There are a lot of very good coaches in the Phillies organization that often don’t get due credit for their work - in this “day and age” it’s more prevalent to criticize than to praise - doesn’t hurt to point out good work every now and again also.

By the way Andy re-introduced a change up into the repertoire that he threw back in 2022 albeit he threw it infrequently back then(I have notes on it from that year) - it’s in place of the splitter and provisions an off speed tumbler into the mix. Back on 6/9/26 I posted an article that pretty much aligned with the issues addressed on Andy https://www.philliesbaseballfan.com/post/6-9-26-comparing-painters - hopefully moving forward he can repeat the delivery and incorporate the pitch mix to be successful.  Btw the pitch that Orion Kerkering is now throwing that’s referred to as a splitter sure looks a lot like a palm ball grip out of his hand - regardless both grips “choke” the ball in the hand delaying the release causing a tumbling action and reduced velocity - it’s again an example of strong coaching as the pitch offsets the high velocity fastball and side to side sweeper he throws with a vertical drop delivery - good stuff!

Reading :

LHP Mavis Graves - promoted to Reading on 7/27/26 the 22 year old has transitioned to the bullpen with developmental plans that he can perhaps become a one to two inning per outing reliever in the show. In his three outings with Reading to date he’s pitched four innings allowing two runs on two hits with seven punch outs. Wet conditions contributed to four walks in his one inning debut on 7/29 - in his next two outings Mavis issued no free passes. Pitching Development Director - Programming Travis Hergert told me that Mavis “spins two breaking balls and gets a ton of whiffs”. Graves features a four seam fastball in the 91 to 94 mph range, slider (cutter), sinker, sweeping curve and a very good change-up. He’s a big fella at 6’6” with a good competitive approach. Lefty relievers can make a great deal of money in the show with specialized skills that lead to longevity - look no further than recent Phillies acquisition Brooks Raley. After 64 minor league starts over four seasons Mavis now embarks on a new path that hopefully gets him further up the development ladder.

RHP Estibenzon Jimenez - “Jimmy” is another starter turned reliever - the affable 24 year old has made 24 appearances this season for Reading - all out of the pen. In 34.1 IP he’s recorded a strong 1.83 ERA and is coming off a stellar month of July posting a 1.69 ERA in 10 games (10.2 IP), a 1.03 WHIP and .190 BAA. He’s always been a consistent strike thrower with a career 67% strike percentage. With a mix of a very good changeup, a four seam fastball that ranges from 94 to 97 mph along with a slider in shorter stints he’s been able to focus on developing a put away swing and miss pitch - the change up has become more of that, with continued consistency and confidence he’s placed himself on the radar for promotion.

RHP Wen-Hui Pan - in his first season back after missing the entire 2025 year rehabbing from TJ surgery the 23 year old fireballer has been a bit sporadic but yet has shown both a major league fast ball and splitter. Pan excelled and dominated opponents while at Jersey Shore this year earning a promotion to Reading on 6/13/26 along with a selection to the Futures game at CBP during the all-star break. The heater reaches upper nineties and triple digits while the splitter dives and can be a put away offering. It’s a matter of reeling in command which hopefully comes with more game experience - seems like a good candidate to me for an Arizona Fall League assignment.

OF Raylin Heredia - the 22 year old from the Dominican Republic is having his best all around season - offensively he’s posting a very legit .278/.311/.481 slash line and .792 OPS with 29 doubles (leads the league), 18 home runs and 56 RBIs with 16 stolen bases generally occupying the third slot in the Reading batting order. Raylin is a good defender in right field as well - in the 8/5 game he threw out a runner at third base, his 6th assist this season. The young man is a winner, he was a key cog in the 2022 DSL championship team, a member of Clearwater’s 2024 playoff team and right in the thick of this season’s push by Reading to win the second half Eastern League title. In my opinion he’s gonna be a big league contributor in the not so distant future.

Jersey Shore :

The Jersey Shore roster was replenished with multiple player promotions from Clearwater as the Threshers were also re-tooled with 2026 draft signees and FCL additions. Here’s a couple new BlueClaws who’ve stood out immediately.

Nathan Humphreys - Nate is a product of the Dallas Baptist program which seemingly always produces strong hitters. The 23 year old outfielder was promoted to Jersey Shore on 7/27 and promptly hit a home run in his first BlueClaws game on 7/30. On the season he’s posted a solid .262/.385/.462 slash line and .862 OPS with 17 doubles, 13 home runs, 45 RBIs and 21 stolen bases. He’s got strong bat to ball skills as a lefty hitter who will take his walks (51 BB, 57 K’s in 339 PA’s) and was a key cog in the Clearwater offense that propelled the team to a first half title in the FSL. He’s also shown strong defensive abilities and has played games in all three outfield positions. Just a hard nosed ball player who knows how to play the game the right way.

Juan Villavicencio - the organization has multiple prospects at shortstop but don’t discount this 21 year old, he has one of the strongest infield arms in the system and can pick it as well. Juan may not have the overall range of his peers at SS but he’s not far off, just this week he impressed BlueClaws Vice President of Communications Greg Giombarrese with his defensive prowess so much so that he texted me about it during a game - that’s good stuff! When I watched the middle infield tandem of Starlyn Caba/Juan Villavicencio a couple years back at the complex in backfields play I envisioned what they might become - Starlyn is now with the Marlins (traded for Jesus Luzardo) and Juan was bitten by the injury bug the past couple years - he’s now healthy and the abilities are shining thru. In 78 combined games (promoted to JS on 7/27) at Clearwater and Jersey Shore he’s posted a .296/.377/.525 slash line and .902 OPS with 17 doubles, 5 triples, 14 home runs, 43 RBIs and 23 stolen bases. He swings the bat from the left side and has legitimate pop - if he stays healthy he’s got a big league tool set - one to watch.

Clearwater :

The Threshers will play in the post season by virtue of winning the FSL West Division first half title. The roster has gone thru a significant transformation as it does every year when the new draft class gets into action. This year though there’s not been a significant drop off in game results and it wouldn’t surprise me at all if Aaron Barrett’s first year as a Manager ends up as a league champion.

Jonathan Hogart can flat out hit - the 24 year old from Murray State has has some down time this summer, his first full pro season, due to some nagging injuries but when he’s played he’s produced. In 298 plate appearances he’s posted a .380 OBP and .878 OPS with 12 doubles, 2 triples, 15 home runs and 55 RBIs. Defensively he’s seen time in both outfield corners and at first base. It may not be long before he’s bumped up to Jersey Shore but until then he’s a top of the order presence for the Threshers.

Dominican Summer League :

This year’s Phillies squad is loaded with talent and it’s shown as they currently hold down first place in their division - Francisco Renteria has posted incredible numbers as has Juan Parra. I plan on writing a feature article soon on this team and will be reaching out to the Phillies DSL leadership group for their input - in the interim I truly enjoy watching this young team play, full of energy! Lots to like on this club.

Player Development Center :

Daily work continues at Carpenter Complex for rehabbing players, new signees not yet assigned to an affiliate and FCL players who stayed after their season concluded for additional training. While there’s no “Bridge League” this year there are live BP sessions where pitchers throw to hitters and simulated game action practices. It’s a bit like extended spring training and the old Instructional League concept without scheduled games against opposing squads. The staff breaks up the practice monotony with different drills and challenges to keep it interesting - I do miss being there as when I lived in the Clearwater area I was a daily observer.
