FanGraphs | Jake Mailhot: The Red Sox were also implicated in sign-stealing but in 2017, and they used a system of Apple watches and conveyed it to runners on second base. And, it worked. The team performed much better on off-speed pitches, significantly better, when a runner was on second base.
Baseball Prospectus | Rob Arthur ($): Based on the available data, it certainly looks like teams are paying nothing for defensive runs saved (FRAA or UZR) in free agency. That could mean two things: their view of defense is vastly different than us, or it could mean the market for defensive runs is grossly inefficient.
ESPN Insider | Craig Edwards ($): Mookie Betts, Kris Bryant, Francisco Lindor, and Nolan Arenado are on the chopping block... why or why not should they be moved? For Betts, it doesn’t make sense in the sense that he’s the second-best player in the league. For Bryant, it may make sense because his trade value is probably at its highest right now. For Arenado, it probably makes more sense to just hope he plays well enough to opt out of his contract, and hope they’re not stuck with the rest.
