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:
Year | Age | Tm | W | L | G | GS | GF | SV | IP | HR | BB | SO | ||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
2015 | 20 | TOR | 1 | 2 | .333 | 2.12 | 31 | 0 | 8 | 1 | 34.0 | 1 | 10 | 40 | 185 | 2.11 | 0.912 | 5.6 | 0.3 | 2.6 | 10.6 | 4.00 |
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.
