Reilly when the AL and NL merged their umpiring staffs in 2000, so when Davidson returned to MLB, he was assigned 61 as his new number. For the 2011 season, he wore number 6, later changing back to 61. Criticism and suspension Davidson was sometimes sharply criticized for his on-field performance, especially for the manner in which he handled confrontations. He was ranked the fourth-worst umpire in the major leagues in a 2011 poll of MLB players.

According to MLB, the suspension resulted from a "culmination of several incidents" as well as Davidson's conduct during the argument with Manuel. Manuel was also suspended for one game.
