The San Francisco Giants have a new cleanup hitter ... 'cause after Logan Webb admitted most players were dealing with "the s***s" following their Mexico City trip, the whole team got hooked up with a ton of Dude Wipes!!
Remember, the pitcher was brutally honest about how the team was doing after their two-game series against the Padres in Mexico City last week ... saying three-quarters of the squad was dealing with the runs.
