Roberto Osuna – So Good, So Young |

The youngest player in the AL this season is Toronto’s setup reliever Roberto Osuna, born in Mexico on Feb 7, 1995. While the 20 year-old is young in years, this is his 5th season as a professional (though he has been used quite sparingly in the minors with just 128.2 IP in four minor league campaigns). Why am I writing about a rookie relief pitcher not even halfway into the season? Well, there’s this:

Those numbers will attract attention on any pitcher’s resume, never mind for a 20 year-old rookie. More on Osuna after the jump.

That workload works out to about 70 appearances and 75 IP for the season. Here are the youngest rookie relievers to do that.

So, if Osuna were to maintain his performance and reach those Games and IP totals, he would be the youngest to do so. He would also be the first among the above pitchers with a WHIP under 1.00, and would join Kimbrel as the only ones with HR/9 under 0.5 and H/9 under 6.0.

But, of course, it’s a long season and it’s a big IF whether Osuna can continue to dominate hitters the rest of the season as he has done so far. To perhaps get a more realistic idea of what Osuna’s final numbers might look like, I looked for pitchers of similar age with similar first half totals. There are 74 pitchers like Osuna who, before age 23 and within the first 50 games of their careers, had appeared in 25 of their teams’ first 80 games of a season. The best of those complete seasons look like this:

Included in the list above are 21 of the 25 players who were closest to Osuna’s performance, with markers over the first half of the season of WHIP under 1.30, ERA under 4.00 and SO/BB of 2.0 or better. With a median ERA+ of the group above at 160 and with all but Eduardo Sanchez (no. 4) logging 50 games and 50 IP, there is certainly established precedent for young pitchers maintaining solid performance in following up a good start to a rookie season.

At no.12 above is Neftali Perez (who, with 69.1 IP, just missed the first list) who has the closest numbers across the board to Osuna’s marks so far. However, Perez and all of the others except Terry Forster (no. 22) were older than Osuna, and Forster’s season above was not a debut campaign like Osuna’s (Forster made 45 appearances and 49.2 IP as a 19 year-old, so his rookie status for the season above seems questionable).

If we look just at rookie relief pitchers aged 20 or younger, only the 24 below compiled 50 IP in a season since 1901, and only half of them posted a 100 ERA+, both markers that Osuna will likely achieve with ease.

Only one of these seasons (Marcos Carvajal, no. 15) is from the past 43 years so Osuna is already on the verge of achieving a very unusual rookie campaign. Doing that while posting eye-popping performance numbers makes his accomplishment that much more noteworthy.

Sorry Doug, I’m going to thread hijack! Though it is Toronto related.

Right now, the Blue Jays are scoring 5.57 runs per game. They have an incredible 0.8 run per game over the #2 offense in the AL (Yankees).

I’m sure there are some Rockie teams that have had a bigger lead than that over the #2 offense.

But otherwise? Well, the ’27 powerhouse Yankees only outscored the #2 offense (the A’s) by .77 runs per game.

BTW, they’re scoring 5.76 runs per game at home, 5.37 on the road. Which strikes me as a fairly normal home/road difference.

Reply to David P

What makes their scoring binge even scarier is they’ve done this with Double-E in a season long slump and their best hitter (Devon Travis) of the first month and a half of the season on the DL since mid-May. But, it probably won’t matter how many runs they score if their pitching (currently ranked 14th in AL WAA) doesn’t get a lot better. Which has me wondering: why spend the big bucks on Russell Martin and (next year) on Josh Donaldson and not upgrade your pitching, more especially since the window of opportunity on Bautista (34) and Martin, Encarnacion and… Read more »

Reply to Doug

Doug – I suspect the Blue Jays approach to improving their pitching was an indirect one. After all, Martin has an excellent defensive reputation, particularly when it come to pitch framing. And the Pirates team ERA dropped by half a run a game when he joined them a few years ago. Donaldson also has a positive defensive reputation (backed up by Rfield).

BTW, speaking of poor pitching (and assuming I did the search correctly), the Yankeees have given up 10+ runs in 3 straight home games for the first time in team history.

Richard Chester

The PI only goes back to 1914. If you go to the Yankees 1912 team page, under Schedule and Results, you will find that they gave up 10+ runs in 4 consecutive games at home against the Red Sox, June 20 to June 22. There was a doubleheader on the 22nd. They lost all 4 games.

Ah, but I said Yankees! That 1912 team was called The Highlanders. 🙂

Seriously, first time in over 100 years this has happened to the Yankees.

yippeeeyappee

Osuna’s only save this season was last night vs the Rays. 2 IP 5k. Given the Jays’ struggles to prevent runs late (see last 2 games vs BAL), I will be surprised if he doesn’t become their new closer soon.

Luis Gomez

Nice to see this kid having success at the big league level, after being signed at a very tender age.

I saw him live for the first time a couple of weeks ago and he´s got a seemingly effortless delivery for that kind of fastball.

Nice coincidence to see his uncle Antonio in the first list. By the way, Roberto´s dad (also Roberto) pitched for a few years in the Mexican League. Oscar Villarreal is still closing games in the Mexican League.

Reply to Luis Gomez

Good catch, Luis. I hadn’t noticed Uncle Antonio there. His age 24 season with the Dodgers wasn’t too far off what Roberto is doing now.

Speaking of 20 year olds, Carlos Correa has now played 15 games.
Tack a 0 on the end of all his numbers to simulate a full season:

100 runs
200 hits
50 doubles
40 homers
110 RBI
40 steals
370 Total Bases

Another hijack but pitching related. Marco Estrada today become the first MLB pitcher to take a no-hitter into the 8th inning in consecutive starts since Dave Stieb in 1988. Both of Stieb’s no-hitters were broken up with 2 out in the 9th.

Reply to RichW

Stieb had three shutouts in 1988 allowing exactly one hit, and two more in 1989. Only pitchers (since 1914) with more are Pete Alexander with four in 1915 (but none the rest of his career), and Nolan Ryan and Bob Feller with nine for their careers.

oneblankspace

I remember a 1985 game against the White Sox where Stieb took a no-hitter into the 9th with a 6-run lead then gave up two homers to Rudy Law and Bryan Little. Gary Lavelle then relieved Stieb, then Harold Baines homered to make it 6-3. Two more singles was all that was left for the Sox.

bluejaysstatsgeek

I had a man-crush on Stieb and it always peeved me to see all the press Jack Morris’s HOF candidacy would get, yet Stieb barely got a sniff. Morris, “Pitcher of the 80s”? Stieb’s numbers were vastly superior.

Jack Russell would be a good guy to come in to the game to mop up for Orel Hershiser.

Reply to brp

Russell’s .376 career W-L% is second lowest (to Milt Gaston) among pitchers with 2000 IP and 95 ERA+. That included a .304 W-L% in 1000 IP for the Red Sox, again the second lowest career mark, this time to Red Ruffing.

Russell evidently saved his best work for the post-season, allowing only one run (a home run) in 12 IP over 5 appearances (alas, that home run was hit by Mel Ott, to win the 1933 WS in extra innings in game 7).
