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.
