Adam Haseley Is Set To Join The Phillies, But Is He The Next Elite Prospect To Arrive Or One To Ignore?


The injury to Andrew McCutchen came at an inopportune time for the Phillies, especially with Odubel Herrera also out.  The acquisition of Jay Bruce helps, but do they trust him in an everyday role?  It wouldn’t appear so, and that’s why we got the news from Jim Salisbury (via Twitter) that Adam Haseley would be summoned to take McCutchen’s spot on the roster.

It’s an interesting decision considering the timing (Haseley was just recently promoted to Triple-A).  That said there were no real alternatives currently on the 40-man roster:

  • Roman Quinn – He’s currently on the IL
  • Dylan Cozens – He’s currently on the IL at Triple-A, and was hitting .167 with 6 HR over 78 AB when healthy
  • Nick Williams – He was just demoted to Triple-A, but was hitting just .175 with 1 HR over 69 AB in the Majors

That left the team in need of an upside play who could get regular AB and potentially make an impact.  Enter Haseley, who we ranked fifth among Philadelphia prospects prior to the season.  Earning a “B” grade, we said:

The team’s first round pick in ’17 (eighth overall), Hasely split time between High-A and Double-A hitting .305 with 11 HR and 7 SB over 466 AB.  Obviously his average was his best asset last season, making consistent contact (8.9% SwStr%).  The problem is just how impressive is that average when it comes from an outfielder who may have a 10/10 type ceiling (he only added 17 doubles and 5 triples, showing that the potential isn’t there for too much more).

His SwStr% has jumped against more advanced pitching this season, with a 10.2% mark over 199 PA.  He’s still shown a strong eye (11.1% walk rate) and also a jump in his power production (11 doubles, 1 triple and 7 HR).  That would help offset other concerns, though are we ready to bet on him having developed into a 20+ HR threat?  Even if we did, is that enough? Consider the split at Double-A:

  • April – .172, 2 HR, 6 RBI
  • May – .337, 5 HR, 13 RBI

Even that power surge is modest, though not overly impressive, and 3 HR came in a two game stretch.  He has the potential to hit for a solid average, though even that’s not a given this first time around (considering his lack of experience against upper-level pitching and rising SwStr%).  He also isn’t a lock to receive regular playing time, just further clouding the issue.

Is there upside and the potential to make an impact?  Perhaps, but don’t expect him to go the route of one of the elite prospects who have recently arrived in the Majors.  Think of him as more solid than spectacular.
