Using Enhanced Gameday, here is a break down of Jair Jurrjens September 11th start against the Texas Rangers. This was Jurrjens first start since coming off the disabled list. In his last start he left the game in the second inning with soreness in the back or his shoulder and neck.

Jurrjens lasted 5 innings picking up the win with a lone first inning run crossing the plate. He allowed only 3 hits and a walk, but he only struck out one batter. He induced 6 fly outs and 7 groundouts.

Pitch Type

Jurrjens typical arsenal includes a fastball, a change up, a curve, and a slurve. My understanding is that the 4th pitch isn’t as refined and isn’t thrown very frequently. Looking at enhanced gameday data, it was tough to differentiate a 4th pitch, so the break pitches are grouped together as curves.

Pitch		Ball	Strike	InPlay	Total
change		9	3	2	14
curve		6	6	2	14
fastball	15	16	12	43
Total		30	25	16	71

Jurrjens threw his fastball 60% of the time, and the other two pitches were thrown 20% of the time. He struggled to control the change up with only 5 of the 14 entering the strike zone.

Jurrjens fastball was clocked from 89 to 92mph with a median velocity of 91.2.

The change up was thrown from 81 to 84 mph with a median velocity of 82.4.

The curve ball was thrown from 77.6 to 80.5 mph with a median velocity of 78.9.

Missing Bats

Of the 25 strikes he threw, 8 were swings and misses, 8 were called strikes, and 9 were foul balls. The curve ball was the trickiest to square up as it induced 4 whiffs, while the fastball resulted in 3 swings and misses.

What gets put in play?

Type		FO	GO	LO	PO	Single	Total
change			1			1	2
curve		1	1				2
fastball	3	4	1	2	2	12
Total		4	6	1	2	3	16

Hitters weren’t able to do much with the offspeed pitches. Then again with only 3 hits and one other line drive they weren’t able to do much with any of the pitches.

Sustaining

Fatigue is always a concern for a pitcher coming off on injury. Jurrjens only threw 71 pitches, but he showed no signs of tiring. He maintained his fastball velocity through the entire start.
