Mat Latos went from Futures to Majors in a week. Latos' debut with the Padres came on Sunday, making him the only rookie pitcher to make his debut in the weekend after the All Star break. Latos throws two fastballs (four-seam and two-seam), a breaking ball (let's call it a slider) and a straight change-up, according to KFFL:

Chris [Hadom] informed me that Latos actually ditched a knuckle change in favor of one with a more traditional grip.

Here's what I found, including the inning from the Futures Game:

Pitch                   #  MPH  PFX_X  PFX_Z
Change             CH   1   83   -3.5   10.5
Two-seam Fastball  F2   4   95   -6.3    8.0
Four-seam Fastball F4  59   96   -2.8   10.2
Slider             SL  14   83    1.0   -0.2

Warm-ups from his debut:

Some Observations

• Fly ball pitcher (28% GB, just 9% LD)
• Attacks the zone (.610 with F4, .5 with SL)
• Slider hasn't offered at (3 swings, 1 grounder, 2 fouls)
• Missed a lot of bats with the fastball (.25 whiff rate on 32 swings)
• Not enough two-seam fastballs (4) and change-ups (1) in the available data
• Possibly three different looks on slider, or inconsistency, or fatigue

Take a look at the three sliders. #3 (shown in yellow) had less sink and more sweep. #2 (dark red) is about the same as the average variety (shown in bright green), #1 was the most curve-like of the bunch, sinking without sweeping like a 12-6 pitch.

Type "3" sliders appeared only at the end of his final inning on Sunday. Something to watch for next time out.
