Interleague play: not quite popular as MLB would have you believe

49 Comments

In the past few years, when interleague play was confined to certain segments of the season, Major League Baseball would issue these press releases about just how popular it was and how attendance spiked dramatically when the interleague series began. The clear impression they were trying to make was just how successful interleague play was as a concept.

Maury Brown at The Business of Baseball, however, crunched the numbers from and concludes that MLB’s enthusiasm about interleague play was really a lot of calendar-dependent noise:

While the rest of the season is yet to be played, the numbers compellingly show that interleague is not as popular as the past numbers have been said to be. It’s not that the “rivalries” aren’t popular, they are (they averaged 30,876 across the Rivalry Week in May this year), but rather balanced interleague throughout the season pulls in pretty much the same crowds as traditional interleague has.

None of this is to say that interleague should be removed. What it does say is don’t use those past numbers as propaganda to say how much more popular interleague is since it came into place in 1997. As the numbers now show, it’s pretty much a wash. Enjoy it for what it is, not some monumental popularity shift added to the regular season.

It was always notable that the big interleague p.r. push came after big weekend series between popular rivals, typically just as the warm weather finally showed up. Now that we have random Philly-Anaheim and Colorado-Seattle matchups in midweek during cold weather and everything else, we are seeing that baseball is, more or less, baseball.

Report: Arquimedes Caminero likely to sign with Yomiuri Giants

Mariners’ right-hander Arquimedes Caminero is nearing a deal with the Yomiuri Giants of Nippon Professional Baseball, according to Bob Dutton of the Tacoma News Tribune. The club has reportedly agreed to sell the 29-year-old’s contract, Dutton writes, though no official move has been announced by either team yet. Caminero is under club control through 2020 and currently ineligible for arbitration.

The right-hander began the 2016 season with the Pirates but was sent to the Mariners in a trade for Seattle minor leaguers Jake Brentz and Pedro Vasquez in order to clear space in the Bucs’ bullpen. With the Mariners, Caminero produced a 3.66 ERA and 8.2 K/9 through 19 2/3 innings in the second half of the year. Although he boasts an electric fastball, one which consistently averaged 98.7 m.p.h. in 2016, his success rate has been tempered by poor control throughout his major league career. According to Dutton, the Mariners’ willingness to sell Caminero’s contract was a strong indication that they did not see him as a viable contender for their 2017 bullpen or as a potential trade chip further down the line.

Should the deal go through, the right-hander will be the second former Mariner to sign with a Japanese club for the 2017 season. Per Dutton’s report, outfielder Stefen Romero also picked up a contract with the Orix Buffaloes of NPB in late November.

Gerrit Cole set to begin throwing program

During the Pirates’ FanFest on Saturday, right-hander Gerrit Cole announced that he is back up to full health after being shut down with elbow inflammation in September. Per Rob Biertempfel of the Pittsburgh Tribune-Review, Cole said he’ll start a throwing program on Monday as he works on regaining his form for the 2017 season.

The 26-year-old pitched through 116 innings for the Pirates in 2016, delivering a 3.88 ERA and 2.5 WARP before landing on the disabled list in June with a triceps strain and again in August with elbow inflammation. It was a steep drop for the right-hander, who saw a considerable spike in his ERA and BB/9 rate and struggled to strike out batters at the 8.7 mark he managed in 2015.

The upside? Inflammation was the worst of Cole’s issues in 2016, and while the newfound health issues didn’t help his case for an extension, a more serious injury doesn’t appear to be on the horizon.
