Octavio Víctor "Cookie" Rojas Rivas (born March 6, 1939), is a Cuban-American former professional baseball player, coach, manager and current television sports presenter.

He played in Major League Baseball as a second baseman and outfielder from 1962 to 1977, most prominently for the Philadelphia Phillies where he first became an All-Star player, and later with the Kansas City Royals where his veteran experience and leadership played an integral role in helping the young Royals franchise develop into a championship team.

[3][4] Rojas was then assigned to Cincinnati's D-level team, the West Palm Beach Sun Chiefs in the Florida State League.

Rojas would finally go north with the Reds at the beginning of the 1962 season and would make his major league debut on April 10.

Although the Phillies already had an All-Star second baseman in fellow Cuban Tony Taylor, Rojas had seen the last of the minor leagues and would man second in 27 games in 1963.

[3] Following the 1969 season in which Rojas hit only .228 and hot prospect Denny Doyle tore through AAA with a .310 average, the Phillies decided to include him in the blockbuster trade that sent slugging first baseman Dick Allen and right-handed pitcher Jerry Johnson to the St. Louis Cardinals for centerfielder Curt Flood, catcher Tim McCarver, outfielder Byron Browne, and left-handed pitcher Joe Hoerner, the trade that led ultimately to Major League baseball free agency.

Kansas City, a team in only its second year of existence, wanted a veteran presence to steady its infield, and in return for the career–minor leaguer Rico, the Royals gained a player who would man second base for most of the next eight seasons and appear in four consecutive All-Star games from 1971 to 1974.

During the 1999 playoffs, while coaching third base for the New York Mets, Rojas was suspended for five games for getting into a shoving match with umpire Charlie Williams while arguing a foul ball call.

His second-oldest son, Mike, is a minor league manager and former MLB bullpen coach for the Detroit Tigers and Seattle Mariners.
