Replay and its unintended consequences


Over at The Classical, Eric Nusbaum looks at a new instant replay system that has been instituted in pro cricket, and notes how it has changed the way the game is actually being played:

Technology changed the way umpires approached their jobs, which in turn has changed the way players approach theirs. The comparison doesn’t work perfectly, but this is akin to allowing baseball players to appeal balls and strikes to a machine with the intention of creating a more accurate strike zone, and with the unintended result being that pitchers start throwing over the middle more, resulting in more home runs. (Or vice versa: batters become fearful and begin swinging at bad pitches, resulting in more of the weak pop ups to the second baseman that Mets fans have nicknamed “Jason Bays.”)

It’s interesting to think about — all big changes are going to bring unintended consequences — but if anything it bolsters the case for the “fifth umpire” version of replay in baseball as opposed to anything else.

By having the fifth ump in a booth who is part of the on-the-field crew, you limit that us-vs.-them mentality that may cause umpires to do different things than they might otherwise do. And by taking out some sort of appeals process or challenge system, you limit the ability of players and managers to game the system.

Report: Athletics sign Trevor Cahill to one-year deal

Free agent right-hander Trevor Cahill reportedly has a one-year deal in place with the Athletics, according to’s Jane Lee. The exact terms have yet to be disclosed, and as the agreement is still pending a physical, it has not been formally announced by the club.

Cahill, 30, is coming off of a decent, albeit underwhelming year with the Padres and Royals. He kicked off the 2017 season with a 4-3 record in 11 starts for the Padres, then split his time between the rotation and bullpen after a midseason trade to the Royals. By the end of the year, the righty led the league with 16 wild pitches and had racked up a 4.93 ERA, 4.8 BB/9 and 9.3 SO/9 in 84 innings for the two teams.

The A’s found themselves in desperate need of rotation depth this week after Jharel Cotton announced he’d miss the 2018 season to undergo Tommy John surgery. Right now, the team is considering some combination of Andrew Triggs, Daniel Gossett, Daniel Mengden and Paul Blackburn for the back end of the rotation — a mix that seems unlikely to change in the last two weeks before Opening Day, as Lee points out that Cahill won’t be ready to shoulder a full workload by then. Instead, he’s expected to begin the year in the bullpen and work his way up to a starting role, where the A’s hope he’ll replicate the All-Star numbers he produced with them back in 2010.
