I can hear the first thought in your head.
"Oil Can was on the Red Sox, not the White Sox, you idiot", would be my guess. And that's where you and your thoughts would be wrong.
Dennis was selected in the sixteenth round of the 1980 amateur draft by the Red Sox. He made his debut with Boston in 1982 and went on to great success, winning forty-three games in a three year span.
Things went downhill after 1986 and found himself finishing his MLB time with the Montreal Expos in 1990 and 91 and the Texas Rangers in 1991. Boyd went off the radar for a couple years, but found himself pitching again in the Mexican League in 1993.
When the strike happened in 1994, the World Series wasn't played for the first time since 1904. The 1995 season was in jeopardy and the owners had to put some type of product on the field. Each club raided their minor leagues and relied on former MLB players and something that resembled the recruiting process in the movie Major League.
Oil Can stepped up and became the most vocal replacement player and in turn became the face of the entire movement. The White Sox signed him to a contract and he was the star player of the replacement team, which came within days of playing actual MLB games. Judge Sonia Sotomayor ruled in the players favor and the regular players started the shortened season.
Shortly after the White Sox stint, Oil Can went back to the Sioux City Explorers. He bounced around the minors until 1997, but pitched again in 2005 for the Brockton Rox, in an attempt to make it back to the majors. He announced his intentions to return to the majors again in 2009, but found no suitors.
