The young second baseman went 2-for-4 in the Mariners' 4-1 win, a seven-inning game designed mostly to get some extra innings for pitchers on both sides.
Ackley drove a fastball over the right-field fence on a full count from left-hander Rob Musgrave, with Chris Gimenez following with another home run on the next at-bat. It was Ackley's blast that had people talking though.
"That's the best one I've hit in a while, I'd have to say," Ackley said. "Best one I've hit this year. It felt pretty good, especially against lefties, who are pretty tough. Just the battle and getting a pitch to hit, then seeing it go off the bat like that is definitely a confidence builder and good for me, as far as continuing through the rest of Spring Training."
Ackley has been hitting well of late. While the "B" game results don't count in official statistics, he's hitting .350 with two doubles and a triple in 20 at-bats in Cactus League action after coming off the bench Monday with an eighth-inning single against the Cubs.
Ackley also has seven walks in 26 plate appearances and a .519 on-base percentage.
"I feel good as far as timing and everything," he said. "Just finding some good pitches to hit and hopefully being a little more aggressive."
Ackley also started a nice 4-6-3 double play in the eighth to help Garrett Olson get out of a jam. But it's his offense that is hard to ignore.
"He's a good hitter. Not too many people can go down and scoop that ball out of there and line the ball the way he did [against the Cubs]," manager Eric Wedge said. "He swung the bat well in the 'B' game as well this morning. He's been swinging the bat well all camp."
