Those six made it to the final round of voting on Phillies.com to select the "Final Phillie" who will be on The Phillies Mural, an eight-story mural created by artist David McShane and the Mural Arts Program that celebrates the history of the franchise.
Callison, Ennis, Kruk, Luzinski, Ruiz and Thome were the top write-in candidate suggestions for the final spot based on thousands of votes cast on Phillies.com during the first round of "Final Phillie" voting, receiving so many votes that the club expanded the voting from five choices to six.
Fans are responsible for choosing the "Final Phillie." Voting is open until 5 p.m. ET on Thursday and can be done here. The mural is scheduled for completion during the summer of 2012 and will be located on a 24th and Walnut Street building, facing the Schuylkill River and the I-76 Schuylkill Expressway.
The images currently featured in The Phillies Mural include: Brad Lidge, Charlie Manuel, Mitch Williams, Cole Hamels, Grover Cleveland Alexander, Larry Bowa, Darren Daulton, Dallas Green, Tug McGraw, Ed Delahanty, Mike Schmidt, Ryan Howard, Chuck Klein, Tony Taylor, Dick Allen, Shibe Park, Jim Bunning, Veterans Stadium, Roy Halladay, Citizens Bank Park, Robin Roberts, Harry Kalas, Richie Ashburn, Steve Carlton, Jimmy Rollins, Chase Utley and the Phillie Phanatic.
Here's a quick look at the six candidates eligible for the "Final Phillie" voting:
Callison, RF, 1960-69: A four-time All-Star and the 1964 All-Star Game MVP after hitting a walk-off home run, Callison's greatest accomplishments on the field came as a Phillie. He was the NL MVP Award runner-up in 1964 and ended his career among the top five Phils in home runs (185) and triples (84). The lefty hitter led the NL in triples twice, doubles once, outfield assists four straight times and double plays once. He batted .300 in 1962 and hit for the cycle in '63. Callison remained in Philadelphia following his retirement, was named to the Philadelphia Baseball Wall of Fame in 1997 and passed away in 2006.
Ennis, RF, 1946-56: A three-time All-Star with nearly 300 career home runs and more than 1,200 RBIs, Ennis was one of the best run producers of his era during his prime with the Phillies. In fact, from 1949-57, Ennis drove in more runs than anyone other than Stan Musial and recorded the eighth-most home runs in the NL. His most impressive season came in 1950, when he led the NL with 126 RBIs and Philadelphia won its first pennant in 35 years. Ennis was a career .284 hitter who slugged 288 home runs and drove in 1,284 runs. Ennis was inducted into the Philadelphia Baseball Wall of Fame in 1982 and passed away in 1996.
Kruk, 1B, 1989-94: Now known as a baseball analyst for ESPN, Kruk was a three-time All-Star with the Phils. Primarily used as a first baseman, Kruk was a key part of the "Macho Row" group that powered its way to an NL East title and World Series appearance in 1993. Kruk hit .316 with a .905 OPS that season, driving in 85 runs and scoring 100 more with a career-high 169 hits and 33 doubles. During his 10-year career, Kruk batted .300 with 100 homers, 592 RBIs and 582 runs. He is the most recent inductee to the Philadelphia Baseball Wall of Fame, earning the honor in August 2011.
Luzinski, LF, 1970-80: A fan favorite known by his nickname, "The Bull," Luzinski was a four-time All-Star and part of the 1980 World Series champion club. He finished among the top eight in the NL MVP Award voting each year from 1975-78, twice being named runner up ('75, '77). Luzinski's best offensive year came in 1977, when he hit .309 with 39 homers, 130 RBIs and a .988 OPS. But his biggest moments came in the 1980 NLCS, when he recorded two game-winning hits to help the Phillies beat the Astros and advance to the World Series. Luzinski was inducted into the Philadelphia Baseball Wall of Fame in 1998 and partly owns the "Bull's BBQ" restaurant in Citizens Bank Park.
Ruiz, C, 2006-present: Still adding to his list of accomplishments with the Phils, Ruiz has already taken part in plenty of memorable moments. He was the primary catcher on the 2008 World Series champion team. In Game 3 of that Fall Classic against the Rays, Ruiz hit a solo homer and recorded a walk-off infield single -- the first of its kind in World Series history -- to give Philadelphia a 2-1 edge in the Series. The fan favorite nicknamed "Chooch" has also been behind the dish for a number of spectacular pitching performances, including Halladay's perfect game on May 29, 2010, and Halladay's NLDS Game 1 no-hitter on Oct. 6, 2010.
Thome, 1B, 2003-05, '12: The eighth player in Major League history to hit 600 home runs, Thome is set to add another chapter to his Phillies legacy. Widely regarded as one of the nicest guys in baseball, Thome signed a one-year deal with Philadelphia following the 2011 season. The powerful lefty hitter is second among active big leaguers in home runs (604) and RBIs (1,674) and fifth in career slugging percentage (.556). Thome's list of accolades is already quite lengthy, several of them being attained during his brief stay in Philadelphia. He received one of his five All-Star nods in 2004, led the NL in home runs in '03 with 47 and hit his 400th homer on June 14, 2004, at Citizens Bank Park.
