Tiger Tales: A Detroit Tigers Blog: Who is Alfredo Figaro?
Lee Panas quickly provides some context around Figaro, from being released by the Dodgers after just one year and his place in the prospect pecking order in Detroit.

Mills wasn't drafted out of high school, or even recruited. So he went to Arizona for his education, and stuck it out despite being drafted a first time.

O'Sullivan took nearly year to sign after being drafted in the 3rd round in 2005.

Figaro throws heat, and not much else (in his debut)

• Four-Seam Fastball (F4): 94.9 mph
• Two-Seam Fastball/Sinker (F2): 93.8
• Change-up (CH): 81.4
• Slider (SL): 83.0

Combined, Figaro threw 96 pitches, including 57 fastballs and 33 sliders. He tossed in just two change-ups and four sinkers. He seems to vary his release point by pitch, but keep in mind, he only threw a half-dozen change-ups and sinkers combined.

Mills didn't last too long, and threw what amounted to a near even mix of three pitches

• Four-Seam Fastball (F4): 87.4 mph
• Change-up (CH): 74.8 mph
• Curveball (CU): 72.2 mph

The latest member of the Junior Moyer Club used his change 32 times, his curve 24 and a total of 38 fastballs. He throws right over the top, and shows almost no lateral movement on his pitches.

O'Sullivan had a good outing, making this group two-for-three in that department. O'Sullivan also appeared in an exhibition game, so we have some extra PITCHf/x data

• Four-Seam Fastball (F4): 90.7 mph
• Two-Seam Fastball/Sinker (F2): 91.1
• Change-up (CH): 77.3
• Curveball (CU): 79.1

O'Sullivan has a very slow change-up. The curve is slurvey, could be/should be re-labeled at some point.
