Jeff is a retired controversial Major League Baseball player who was a castaway on Survivor: Philippines and a member of the Kalabaw tribe. Right away, he wanted to get rid of Penner and the other returning players, feeling their time is over and that a new person should win. Jeff assumed the leadership position on Kalabaw tribe, all of whom dominated the 3-tribe portion of the game along with Tandang. In order to keep tabs on Penner, whom he still perceived as the enemy, he formed an alliance with him and Carter. Jeff injured his leg early on in the game, and kept that a secret, along with his identity. Dawson, however, knew whom he was. When Matsing was absorbed by the two tribes, Kalabaw received Denise, whom Jeff quickly recruited into his alliance. On Day 12, Dana Lambert quit the game due to her illness, giving Jeff鈥檚 side of the Kalabaw tribe the numbers. Kalabaw lost the next two immunity challenges, and Jeff orchestrated both Dawson and Katie鈥檚 exits one by one, although Katie almost convinced him to target Penner when they had the chance.
