In 1985, Randy Bass [Bass’ NPB stats are about 3/4 of the way down the page] had reached 54 HRs with one game to play in the NPB season. In the last game which Bass’ Hanshin Tigers played against the Yomiuri Giants (the team Oh had played for and was then managing), Bass was walked intentionally all four times he came to the plate to prevent him from tying or breaking the record. Another source says that the Giants tried to walk Bass every time he came to bat during the three game series, but that Bass got a single hit by throwing his bat at the ball on one of the pitch-out attempts.
Testosterone can be administered parenterally , but it has more irregular prolonged absorption time and greater activity in muscle in enanthate , undecanoate , or cypionate ester form. These derivatives are hydrolyzed to release free testosterone at the site of injection; absorption rate (and thus injection schedule) varies among different esters, but medical injections are normally done anywhere between semi-weekly to once every 12 weeks. A more frequent schedule may be desirable in order to maintain a more constant level of hormone in the system.  Injectable steroids are typically administered into the muscle, not into the vein, to avoid sudden changes in the amount of the drug in the bloodstream. In addition, because estered testosterone is dissolved in oil, intravenous injection has the potential to cause a dangerous embolism (clot) in the bloodstream.
Let's see if this season's new ball is contagious enough to give it's players some new cajones as well. I remember watching good ol' Tuffy. To confirm my memory didn't rewrite history, I checked the web to confirm. Indeed, "In the 2001 season, he hit his 55th homer to tie Sadaharu Oh's Japanese League single season home run record, set in 1964. For the rest of the season, opposing pitchers intentionally walked Rhodes to prevent him from breaking Oh's record." Then I looked up Cabrera. "Like Rhodes, Cabrera would see few good pitches for the remaining games after tying the record." With 21 games left, I sure hope things have changed in the past 10 years.
