It's an intra-squad game, the first of camp, though some Seattle Mariners are taking it far more seriously than others.
For veterans, it's no more than a few at-bats and the chance to get the jitters out on the field. For rookies, however - like pitchers Dan Hultzen, Taijuan Walker and James Paxton - it's the first time facing major league hitters who don't know what's coming.
"They've all throw batting practice, but there the hitter knows what's coming," pit ching coach Carl Willis said. "I imagine their heart rates will jump a bit."
Catcher Jesus Montero remembered his first intra-squad game, with the New York Yankees, and had a three word description:
"I was scared," he said.
"First at-bat, I hit a home run to right field," Montero said. "Rounding the bases, I was thinking 'How the heck did I do that?'"
