Here are some traditional stats:
So Mariner pitchers are better than league-average in ERA, but worse than average in FIP. Being slightly above-average in allowing walks and allowing HR is what accounts for that.
Here are batting-against stats:
So you don’t have to do the math, league-average ISO is .141, Mariners ISO-allowed is .162. That, and the BABIP-allowed that is 28 points below average, confirms the FIP indication that the Mariners have been fortunate on the ERA front.
In other words, it could have been worse. M’s pitchers have gotten away with fewer hits and fewer runs than objectively they “should have.”
Their OPS-against is right on league-average, but that’s only due to the advantageous BABIP.
As it happens, though, the fortunate streak hasn’t helped much due to the moribund offense.
Noteworthy here is that the Mariners might be a bit on the unfortunate side on HR-per-fly-ball, since they are a bit above-average there. If that evens out, it would bring down that ISO-against figure which so far is mostly driven by homers (note that total XBH% is average).
Now the Brainstorm Designer Stats, in order of IP. The four middle columns are rate stats re-scaled to the 10-year MLB average equal to 100. The three right columns are my stats measuring (1) getting non-random outs; (2) preventing non-random offense; and (3) combining the two. So a number on the far right over 100 is what you look for. The names in green on the bottom have even less data than the ones above, so there’s not much meaningful there.
When we ran our hitting stat portrait, only Corey Hart measured up as hitting above-average at the time. Not so with the pitchers. Of course, there’s also a smaller amount of data, so you can’t draw too many conclusions.
Needless to say, Felix looks dominant, as he should. And the rest of the “rotation”? — pretty much what you’d expect. Paxton was off to a great start. Brandon Maurer’s single appearance was very promising. But Elias and Young have been pretty dependent on good fortune.
In the bullpen, Rodney has been white-knuckle and then some (15 baserunners in 7.1 IP), but he’s given up only one extra-base hit (a double), so he’s not getting hit hard yet, and he grades out pretty well. Similarly Beimel hasn’t been hit hard despite not appearing to have much to offer.
Leone and Farquhar have struggled with BB-allowed, but have been solid otherwise. Wilhelmsen has struggled even more with BB-allowed, and has not been solid otherwise.
Maybe that pecking order is changing, since Wilhelmsen hasn’t appeared in the last three games, and it was Medina in the 8th on Friday night.
Leone should be moving up pecking-order-wise, but he’s yet to enter the game in the 6th or later with the lead. Maybe we’ll start to see that. It’s interesting, though, that he’s already 5th on the team in innings pitched.
