Good morning baseball fans!
The big news from yesterday was Aroldis Chapman being suspended 30 games by MLB.
After rumors about an extension surfaced on Monday, the Royals inked Salvador Perez to a five-year extension.
Marlins reliever Carter Capps was forced to undergo an MRI, and Miami might have to look for a new reliever.
Beyond the Box Score's Ryan Romano talked about rethinking pitcher overperformance using some advanced statistics.
For these metrics, the same general principles as ERA-FIP apply. When a pitcher has a large difference between, say, his RA and DRA in one season, he's probably lucky. When he maintains that disparity over several seasons, it may stick around long-term. Someone such as Zeigler, who has always blown past his indicators, could continue to do so going forward. Exercise caution, until the sample increases to a safe amount.
All three of these differentials have their uses. As a replacement for ERA-FIP, however, I would use DRA- and cFIP. That way, you get one descriptive metric and one predictive metric, like you do with ERA and FIP. But DRA-RA still has use, and so does (FIP-)-cFIP. In distinct ways, each will tell you how well a pitcher should have fared.
Chris Mitchell of FanGraphs wants Dilson Herrera freed.
Herrera’s first taste of the big leagues was a little rough, but his offensive showing wasn’t half bad for a second baseman. It’s also worth noting that his time in the show was interrupted by a broken finger, which may have negatively affected his performance. Big league performance aside, everything about Hererra’s minor league track record suggests he’ll make for a very good second baseman. And his Triple-A numbers suggest he could be that as soon as this year. Whether he gets that opportunity remains to be seen.
