I might as well throw out all the usual caveats up front. It’s April. Sample sizes are still miniscule. The ball might be different. The rules are definitely different. I could go on. All of that is true, but it doesn’t change this essential fact: José Alvarado is on an otherworldly tear right now, putting up best-reliever-in-baseball numbers for a Phillies team that desperately needs the help.
Let’s start with the numbers, because they’re overwhelming. Alvarado has faced 29 batters so far this year. He’s struck out 18 of them. That’s a 62.1% strikeout rate, or as I like to call it, a made up strikeout rate. You can’t conceive of a 62.1% strikeout rate. It’s nonsense math. Nearly two-thirds of the batters who have come to the plate against Alvarado this year have walked back to the dugout with nothing to show for it but a sad face.

Alvarado has posted a 20.8% swinging strike rate so far this season, seventh-best among relievers even in the small sample of April, when outliers rule.
