Jack Sr. and his son Jack Jr. founded Jack Cust Baseball in 1997. Jack Sr. is well known and respected throughout the state of New Jersey for his contributions to baseball and for his wealth of knowledge and guidance he continues to pass on to players in the college recruiting and major league draft process. After having trained all three of his own sons, Jack Jr., Kevin and Mike, each was drafted out of high school by major league teams.
An accomplished player himself in the 70′s, Jack played at Cathedral HS and went on to play collegiate baseball for Mike Sheppard at Seton Hall University. There he hit a grand slam in the NCAA Regional Final in the 9th inning to lead Coach “Shep” to his first College World Series appearance. Jack Sr. is responsible for the development of our hitting curriculum we call “The Process” that is preached in our Nationally Acclaimed Hitting School.

On November 15, 2004, he was signed by the Oakland Athletics. He spent the whole season in Triple-A Sacramento and was granted free agency after the season. On December 6, 2005, he signed a minor league contract with the San Diego Padres. He just had 3 at-bats in the 2006 season. Cust began the 2007 with the San Diego Padres Triple-A team, the Portland Beavers. On May 3, 2007, the Padres traded Cust to the Oakland Athletics. The Athletics needed another designated hitter due to an injury to veteran Mike Piazza. Cust quickly endeared himself to A's fans by hitting 6 home runs in his first 7 games. Cust would hit .346 with 14 RBI during the seven-game stretch. On May 13, 2007, with two outs and an 0–2 count in the bottom of the ninth, the A's rallied to score 5 runs to beat Joe Borowski and the Cleveland Indians 10–7, with Cust hitting a walk-off 3-run home run.
After hitting .348 with 1 double and 5 home runs along with 13 RBI, Cust shared Co-American League Player of the Week honors along with teammate Dan Johnson for the week ending May 13, 2007. On August 10, 2007, Cust hit his first major league grand slam off relief pitcher Macay McBride of the Detroit Tigers. He also hit a 3-run double earlier in the game to give him a career high 7 RBI. He finished the 2007 season leading the Athletics in home runs with 26. In 2007, he walked 21.0% of the time, tops in the major leagues.
On December 12, 2009, Cust was non-tendered by the Athletics making him a free agent. On January 7, 2010, Cust re-signed with the Oakland Athletics on a 1-year $2.5 million contract. However, he was designated for assignment on April 3, at the end of Spring training. On April 7, Cust cleared waivers and was outrighted to Triple-A. During his 33-minor league game tenure, he hit .273 with 4 home runs and 19 RBIs. On May 15, he was added to the 40-man roster and recalled. He appeared mostly in the outfield until Eric Chavez ended up on the DL, then assumed the primary DH spot. On September 13, Cust hit his 100th career home run in a 3–1 Athletics victory over the Kansas City Royals at Kauffman Stadium
