OK, so it’s hardly the heart of darkness, but back in the 1970s, pitchers in preseason exhibitions occasionally threw complete games as they prepared for the Nippon Professional Baseball season.

When you look at old box scores, the numbers of pitches thrown by starters can be an eye-opener, but the sight of seeing a guy throw 90 pitches in an exhibition game on March 1, 1975, catches one’s attention. The pitcher in question, journeyman right-hander Toru Hamaura, threw 91 pitches over five innings that day for the Fukuoka-based Taiheiyo Club Lions.

This was when teams looked at innings, rather than pitch totals — although pitch counts were dutifully reported in Japan’s sports newspapers. What you notice is that guys aren’t throwing more than six innings the first two weeks.

So while innings were curtailed, Hanshin Tigers veteran Tomohiro Tanimura threw 111 pitches over five innings on March 11. Shigeo Nagashima, then a rookie skipper with the Yomiuri Giants, may have just been showing off on the same date in Florida, when Osamu Shimano was allowed to throw a 100-pitch complete game in the Grapefruit League.

By the third week of March, seven-inning starts and 100-pitch outings became more and more common. One of the features of the schedule then was a large number of double headers, and this even penetrated the preseason, with teams frequently playing two. In a March 23 doubleheader against the Yakult Swallows, Satoshi Niimi threw 124-pitch complete game in the opener, while Fighters ace Naoki Takahashi wrapped up the nightcap with an efficient 113 pitches. The apex or nadir — depending on one’s view point — came on March 27, when Lotte Orions ace Fumio Narita threw 144 pitches over nine innings.
