Pitch count appears to the be the topic of the year at mopupduty.com . At what point do the Jays look at Brandon Morrow’s pitch count and decide to shut him down?
In 2008 (64.2) & 2009 (69.2 IP) Brandon Morrow threw a combined 2370 pitches. As of August 24th Brandon has thrown 2354. And Morrow hasn’t just been playing country hard ball this season
According to the pitch f/x data that Fan Graphs collects, his overall fastball percentage is down from a historical rates of 70% (2008 & 2009) to 58.5%. Previous fastballs are now curves and change-ups.
I originally assumed that a good portion of his pitches came earlier in the season. I like to think this is logical, as Morrow’s ERA of 6.66 & BABIP of .390 in starts 1-10 are much higher than in starts 11-22 (3.03 ERA, .304 BABIP).
Back on July 23rd I wrote an article that calculated the total number of pitches required for each out. As of July 23rd he averaged 5.7 pitches per out.
Since that time Brandon has averaged… 5.7 pitches per out (91 outs over 519 pitches, including 46 K over 30.1 IP in 5 starts)
The fact remains that Shaun Marcum has pitched 151 innings (roughly 15 more than Brandon), yet he’s only throw 2356 pitches.
What I’m driving at here is Morrow’s seemingly pedestrian 137.1 IP is in actuality closer to 150+ for the average pitcher in terms of pitches thrown.
If he tosses 17 pitches and 2.0 IP this weekend he will have doubled previous highs.
At what point do the Jays pull the trigger (if at all) and sit Morrow down for the rest of the season?
