A game in which adjustments are paramount can flummox even the best of players. What separates the haves from the have-nots is the ability to make changes on the fly.

Consider Jackson Holliday a quick learner.

Baseball's 10th-ranked prospect according to MLB Pipeline shook off a pair of hitless games -- his first two in High-A -- and broke through with a homer, a triple and two RBIs to lead Aberdeen past Wilmington, 7-2, on Thursday night at Frawley Stadium.

Holliday entered the game hitless in seven at-bats with the IronBirds after his promotion from Single-A Delmarva on Monday.

Currently the youngest player in all of High-A at 19, Holliday notched his first Aberdeen hit with a triple to center field in the opening frame. The son of former All-Star Matt Holliday went one better during the IronBirds' five-run second, hammering his third homer of the season.

All of Holliday's long balls have come in the past five games, beginning with his first multihomer effort as a pro on April 21 with Delmarva.

“High-A’s a big jump from Low-A; we’ve seen that with most players we’ve sent up there,” Baltimore director of player development Matt Blood told MLB.com after Holliday's promotion. “We feel like it’ll be a challenge for [Holliday], and we expect him to have some growing pains. But he’ll work through it, I believe, and it should be really good for him.”

The initial growing pains proved to be short-lived.

The performance raised Holliday's OPS 1.139 and his extra-base hit total to 11 in 63 at-bats. Overall, last year's No. 1 overall Draft pick is slashing .349/.488/.651 with more walks (17) than strikeouts (16) in 16 games.

Holliday put together a tremendous senior year at Stillwater (Okla.) High School, hitting .685/.749/1.392 and setting a national record with 89 hits. That excellence not only earned him a record-setting $8.19 million signing bonus -- the highest ever given to a high school player -- it also set the stage for a strong pro debut that included a .911 OPS in 20 games last summer.

“He played very well in Delmarva and showed that he’s one of the best players in the league in, really, all indicators, and that he needed to be challenged more appropriately,” Blood said. “This [was] the right time to do it.”
