Name: Aaron Altherr
DOB: 1/14/91 (20 as of April 1, 2011)
Weight: 190 lbs
Acquired: 9th round, 2009 ($150,000 bonus)
Pre Draft Report: Having played both baseball and basketball coming out of high school, Altherr was considered to be raw in many facets of the game. Although he was considered raw in many facets of the game, he was heralded for his five tool potential. Showing his athletic ability, he played shortstop in high school. Although known in the scouting community, there were few published scouting reports of Aaron coming out of high school.
Hit: Altherr’s swing is fine through the zone, though it can get a bit long at times.. The problem is that Altherr’s length gives him some natural swing and miss. At this point Altherr’s biggest room for improvement is in his pitch recognition, learning to get himself in a position to hit for power. 35/45
Power: It wasn’t until 2013 that Altherr started putting his power into game play. Altherr is still filling out and he has good use of his whole body into generating that power. Right now the power plays as below average, but there is a chance that as he fills out more that it could play as average or above long term. 40/50
Speed: When underway Altherr is a plus runner and it plays as such in the field. Due to his size it more of a long stride which makes him not very fast home to first. The worry is that if he thickens with age his speed will decrease, and will affect his defensive abilities. 60
Glove: Right now Altherr is a true centerfielder defensively. As he gets older the speed is likely to decrease and Altherr will have to maximize his route running and conditioning to maintain the ability to stay in center field. 50
Arm: Over the years Altherr’s arm has been rated from average to plus. Either way it is plenty for right field and is a weapon from center field. 55
Summary: Altherr has less upside than he did a couple of years ago, but that has been replaced by more safety. If he can close some of the holes in his swing and stay in centerfield, he is a major league regular in center field. In a corner he is more a fringe regular or fourth outfielder. At this point Altherr’s floor is as a backup outfielder and should have a long major league career.
Having only played in the GCL and the NYPL, there are not many videos out there. In fact, this is the only one I could find.
It’s a little tough to see in the video, but you can see how much Altherr has to fill out. Another thing to take note of is how he is relatively short to the ball and his bat speed. The combination of these two abilities is somewhat of a surprise from someone who is still far from his potential. Altherr should be a must follow for Phillies fans this coming season.
Update: Altherr finally broke through in 2015 with good seasons in both Reading and Lehigh valley. Good enough to warrant a call up to Philadelphia on August 18, 2015. He seemed sure to make the team out of spring training in 2016 when a wrist injury/surgery sidelined him until July 28, 2016. This spring will determine if he goes north with the team as a 4th or 5th outfielder.
