Jackson, who has primarily hit first or second, found himself in the No. 7 spot in the lineup against Giants lefty Jonathan Sanchez.
Jackson is just 1-for-14 so far on the team's road trip and is hitting just .227 with no homers and seven RBIs this year. Usually even when he's not hot at the plate, Jackson still draws walks, but lately he has not been doing that and his on-base percentage has fallen to .309.
To Hinch, it looks like Jackson is pressing.
"He hasn't looked the same for the last couple of series," Hinch said. "He's swinging out of the zone a little more often, swinging and missing a little more often, not drawing walks, not getting as many hits. It tends to weigh on a guy. He's hit a lot of balls in the air, too. He's probably putting a little extra into his swing and trying to get too much out of himself. Maybe down in the order he'll take a deep breath and relax a little bit."
One of the reasons Jackson remained in Saturday's lineup was his success against Sanchez. Jackson came into the game 9-for-20 with a double and two homers against the lefty in his career.
