First off, I’m not some old-timer* grousing some nonsense like, “Yeah, Tom Gibson threw 300 innings a year in the 60s and he’s in the Hall of Fame.” I am a firm believer in watching and indeed ‘coddling’ young pitchers. I think there’s a special circle of hell being sized for Dusty Baker’s waistline right about now. I think there’s no doubt that the Mets flat-out destroyed Dwight Gooden’s career, and for that matter they didn’t do Ron Darling any favors either. Protecting pitchers good, abusing pitchers bad.
But is Pelfrey being abused this year? He is going to pitch more innings than he ever has in his pro career. If he averages 7 IP a start over the next five starts, that puts him at 198 for the year, versus 152.2 in ‘07 and 117.1 in ‘06. Sounds bad. But could it be that the innings are getting easier, now that Pelfrey has quit walking the park, and the Mets have agreed to turn the occasional DP behind him? Allow me to steal reference material from Danny:
Pelfrey, 2007: 17.7 P/IP (major leagues only)
Pelfrey, 2008: 16.4 P/IP
When we look at pitches thrown it doesn’t appear as dire. Pelfrey did throw 119 pitches against the Rockies on July 13, working eight shutout innings. Apart from that effort, he’s been right around 100 pitches every time, and he throws some 98% fastballs — easy on the arm. In fact, he’s thrown between 98 and 102 pitches in 13 of his 26 starts, which sounds like he’s actually on a pretty strict pitch count, to me.
It won’t prove anything to point out that Pelfrey isn’t throwing as many innings at age 24 as Pitcher X, whose arm got blown out. Nor would it prove anything to compare his workload to someone whose arm hasn’t been torn to shreds. For every Brandon Webb I bring up, you can bring up an A. J. Burnett. Before long somebody’s going to mention Livan Hernandez, and that’s not good for anybody.
Instead, let me just end with this idea: If there are pitchers on the Met staff who need rest, it’s not the starters — it’s the bullpen. Heilman, Sanchez, Pedro2, even Joe Smith and Scott Schoeneweis pitch in 70 to 80 games a year. And that doesn’t even account for the two times a week where they warm up in the seventh inning, air it out in the pen, and don’t actually make it into the game. That’s their night off.
So I wouldn’t fret if Pelfrey keeps showing up in the ninth inning, as long as he’s cruising. If he’s thrown 135 pitches through eight, though, I’ll go gangsta on Jerry as fast as anyone else.

the fact that pelfrey has seen ninth inning twice this year, and wasn’t coming out of the bullpen to do it, is still amazing to me.

Re: Pelf and pitch totals
In 2007, he threw 1285 pitches at the major-league level. Other than digging through minor-league box scores, we’re not going to get a pitch total for his starts in the minors, but we can use this formula (3.3 * PA + 1.5 * K + 2.2 * BB) to get an approximate total of 1299. That brings the combined pitch total to 2584 over 152 2/3 innings, or about 16.9 pitches per inning.
If Pelfrey threw exactly 30 more innings than last year with the same number of pitches per inning, that would be 3092 pitches. His current total is 2669, so if you prefer to look at it from a pitch standpoint than an inning standpoint he has 423 pitches to go before he hits the danger zone, a milestone he’s likely to hit midway through his fifth start from now.
Nice analysis, Jessica. At his current rate of 2669/163 = 16.374 pitches/IP, 423 pitches would be reached in about 26 innings. That’s less than 4 games at 7 IP/GS.
Interesting data. My feeling is still that Pelfrey will be okay throwing 200 innings and/or 3200 pitches, as long as he isn’t forced to throw 120 in any given start. (I’m still leaning on the “it’s not pitching that hurts your arm, it’s pitching when tired” pillar over here.)
