Are They Good: Best ERAs Since the Break?
It’s been about a month since the All-Star break and we’ve seen a host of interesting arms put up excellent ERAs. Some of them are just studs being studs (Max Scherzer 1.32, Carlos Carrasco 1.56, Rich Hill 1.78, Aaron Nola 2.16, Trevor Bauer 2.21, and Clayton Kershaw 2.23), but others have come from unexpected sources so let’s look under the hood of those guys to see what’s up.
(listed in ascending order of ERA)
Trevor Williams, PIT | 0.75 ERA, 1.21 WHIP in 24 IP
Williams has the best qualified ERA over the last 30 days (Chris Sale has a 0.00 ERA in that time, but only 17 IP), but there’s nothing supporting it. His insane 98% LOB rate is doing virtually all of the heavy lifting. Obviously, any sustained period of sub-1.00 ERA performance is going to have some outlier metrics involved and it’s usually going to involve a mix of peak skills and good luck, but it ranges from average to truly bleak outside of the LOB rate.
