With that in mind you can understand why I've never gone in for the recent multi-sport sets that BBM has issued. They did their first one - Masterpiece - in 2016 to celebrate the 70th Anniversary of BBM Magazine Sha, the magazine publisher that is BBM's parent company. They followed that in each of the next two years with a set called Infinity. All of these sets have featured baseball players but for the most part I've felt they've just had a kind of run-of-the-mill selection of players. I say for the most part because I was interested in (and asked Ryan to get for me) three of the cards from the 2017 set that featured famous amateur players.
I noticed something interesting about the baseball players in the 2018 set - they all fell into one of two categories. Either they spent time playing in MLB (or at least MLB organizations) or they were related to another baseball player. There are 36 baseball cards in the set and 26 are of players with experience in North America - Masanori Murakami, Satoru Komiyama, Masao Kida, Keiichi Yabu, So Taguchi, Tsuyoshi Shinjyo, Yasuhiko Yabuta, Tadahito Iguchi, Hisanori Takahashi, Mac Suzuki, Kenshin Kawakami, Hideki Okajima, Yoshinori Tateyama, Kenji Johjima, Akinori Iwamura, Koji Uehara, Kazuo Matsui, Kosuke Fukudome, Ryota Igarashi, Kyuji Fujikawa, Daisuke Matsuzaka, Tsuyoshi Wada, Kensuke Tanaka, Norichika Aoki, Tsuyoshi Nishioka and Toru Murata. (Off hand this is probably less than half of all the Japanese players to play in MLB.) The remaining ten players can be grouped by their familial relationships - there's the father/son duo of Katsuya and Katsunori Nomura, the uncle/nephew duo of Tatsunori Hara and Tomoyuki Sugano; the brothers Matsunuma (Hirohisa and Masayuki) and Tomashino (Kenji and Seiji) and the brother/sister pair of Shingo and Yuki Kawabata.
I asked Ryan to pick up only one of these 36 cards - the card of Yuki Kawabata:
The set had an interesting subset however called "Family Ties" that showcased the relationships between the ballplayers. I asked Ryan to pick up all five of the baseball related ones (the subset actually contains 13 cards - the others show relationships in track, curling, sumo, wrestling, football and motor sports. One of the families showcased are the three Murofushi siblings who I think are all hammer throwers). (And I don't know why the Hara/Sugano card is "Kinship Ties" rather than "Family Ties".)
