Clemens has been the focal point of several controversies. His reputation has always been that of a pitcher unafraid to throw close to batters. Clemens led his league in hit batsmen only once, in 1995, but he was among the leaders in several other seasons. This tendency was more pronounced during his earlier career and subsequently tapered off. After the 2000 ALCS game against the Mariners where he knocked down future teammate Alex Rodriguez and then argued with him, Seattle Mariners manager Lou Piniella called Clemens a "headhunter." His beaning earlier that year of Mike Piazza, followed by throwing a broken-bat in Piazza's direction in the 2000 World Series, cemented Clemens's surly, unapologetic image in the minds of many. In 2009, former manager Cito Gaston publicly denounced Clemens as a "double-talker" and "a complete asshole". Clemens was ranked 14th all-time in hit batsmen after the 2020 season. 14th all time may be misleading, as his rate of hit batsmen per batter faced is not out of line with other pitchers of his era at 1 hit batsmen per 125 batters faced. Numbers reflect similar rate of hit batsmen to pitchers such as Nolan Ryan, Justin Verlander, Greg Maddux.
