Meet Sean O'Sullivan

All right, it is about time to get a close up look at Sean O'Sullivan.

 

Age 22

Height and Weight

6'2" 230 lbs – mlb.com and b-ref

6'1" 222 lbs – baseball cube

 

He is a big boy and can use to lose a few pounds. I like to use all three sources to see if there are any dependencies. The Baseball Cube is always a little behind, so it looks like he has gotten bigger over time.

 

Stats

 

I don't like to use FIPS or ERA without knowing the exact league and park factors in the minors, so here are his K/9 and BB/9 through the minors and majors along with his MLB ground ball rate.  I combined his 2009 and 2010 major league stats are all data because of his limited time in the majors.

 

Season	Team	K/9	BB/9	GB%
2006	Angels (R)	6.94	0.88
2007	Angels (A)	7.11	2.27
2008	Angels (A+)	6.32	2.85
2009	Angels (AA)	6.75	0
2009	Angels (AAA)	6.26	2.61
2009/10	Royals and Angels	4.91	2.58	38%

 

He is a much better strikeout pitcher in the minors than so far in the majors, with a fairly consistent walk rate.

 

Here is a breakdown of how much hitters are swinging at his pitches:

 

Contact Rates
Outside Swing %	Outside Contact %	Strike Swing %	Strike Contact %	Swing Strike %
19.7	72.2	42.9	97.8	5.8

 

Almost 98% of pitches swung at in the strike zone lead to contact.  He really has problems missing bats.

 

Pitches

 

Sean throws 3 pitches and here is how often and with what success (the higher the run value the better the pitch):

 

	FB	CB	CH	Unk
% Thrown	61.5	22.9	15.5	9.3
Run Value/100 PITCHES	-1.89	0.72	3.59

 

He doesn't have much success with his fastball, which he throws the most.

 

Finally, here is a look at the speeds of each pitch along with the grip I think he uses (these could be wrong, so feel free to correct me).

 

Fastball (ave = 90 mph)

Curve Ball (ave = 78 mph)

 

Change up (77mph)

 

Well, that is all I have for now.  Feel free to ask any question if any of the information is now clear.
