NPB Bullet Points: Four Unrelated Notes

Title says it all, here are the bullet points. Everything's in Japanese for this edition:

• Remember Naoya Washiya, the California jr college player who was drafted by Washington last year? He's been released and has returned to Japan.
• Orix is bringing former KBO and 3A pitcher in Hyang-Nam Choi for a workout. Choi is 39, but prior to this season he put up good numbers in 3A stints with Cleveland and LA, including a very solid season last year as a reliever in Albuquerque, a notoriously hitter-friendly environment.
• Rookie Yusei is returning to Seibu's farm team after a two-month layoff due to shoulder discomfort. I've written very little about the prospect formerly known as Kikuchi this season, but his pro career is off to a bit of a rough start.
• Yu Darvish's July 3 start is available on justin.tv, spread across 1 2 3 links. Darvish showed great velocity, struck out 10, and worked from the stretch all the time in this game. Darvish set a new NPB best with a 155 km/h fastball, which he threw by Masato Nakamura on an 0-2 count. The pitch can be seen at about 47:22 of the first link.
