On June 8, 2007, shortstop Julio Lugo of the Boston Red Sox caught Alberto Callaspo of the Arizona Diamondbacks. However, third baseman Lowell, Lugo's teammate, claimed it was not a true hidden ball trick since the pitcher did most of the work ''selling'' the trick. Before Lugo caught Callaspo, Lowell laid claim to the last successful hidden ball trick and held that position for eight years to the day. Lowell's occurred on August 10, 2005, when he, then with the Florida Marlins, caught the Arizona Diamondbacks Luis Terrero, with reliever Todd Jones on the mound. Lowell also caught Brian Schneider of the Montreal Expos in 2004.

Can we conclude that can the pitcher be on the mound during a hidden ball trick?
yes
