CLEVELAND -- Jackson Holliday returned to the big leagues on Wednesday in Baltimore. The 20-year-old solidified his status as a big leaguer this weekend in Cleveland.

The breakout of MLB Pipeline¡¯s No. 1 overall prospect was on display during the Orioles¡¯ four-game series vs. the Guardians at Progressive Field, and it continued on Sunday afternoon, when Holliday swatted the second home run of his 15-game MLB career. The blast helped power a 9-5 win for Baltimore, which split a four-game set vs. MLB¡¯s top team.

The start of Holliday¡¯s second stint with the O¡¯s has gone completely different from the first.

In April, Holliday went 2-for-34 with a pair of singles and 18 strikeouts over 10 games. This time, he is 7-for-18 (.389) with two home runs and seven RBIs in five games since being recalled from Triple-A Norfolk.

Even Holliday¡¯s body language indicates how much more comfortable he is in the bigs.

¡°I think definitely just having my feet under me [helps],¡± Holliday explained earlier in the weekend. ¡°Being able to come to the ballpark and have a normal schedule. And just being able to go out there and play, have fun and kind of put everything else to the side ... just enjoy being out there.¡±

Holliday¡¯s second homer was a Statcast-projected 362-foot shot to right field off Cleveland starter Gavin Williams during the fourth inning that pushed Baltimore¡¯s lead to 4-2. It was his first road home run, as his previous homer was a Eutaw Street grand slam during Wednesday¡¯s win over the Blue Jays at Camden Yards.

Holliday finished 2-for-4, also collecting a two-out single in the seventh. It was his third consecutive multihit game -- his first three in the big leagues -- going a combined 6-for-11 with two RBIs from the No. 9 hole in the Orioles¡¯ lineup over that span. (Meanwhile, he set records on the ¡°Golden Tee Golf¡± arcade game in the visitors¡¯ clubhouse in his free time.)

¡°Showing a lot more confidence. The way he can stay on the baseball is much improved,¡± manager Brandon Hyde said. ¡°He¡¯s going to have some ups and downs. He¡¯s a really, really young player. But it¡¯s great to see him swing the bat this way this series.¡±

Sunday¡¯s fourth inning was a perfect example of just how potent the O¡¯s young lineup can be.

After Holliday¡¯s homer, Colton Cowser singled to extend his career-best hitting streak to 17 games, matching an Orioles rookie record set by Trey Mancini from Sept. 11-29, 2017. Then, Gunnar Henderson pushed Baltimore¡¯s lead to 6-2 with a two-run homer -- his 29th of the season, but his first since July 14 (prior to the Home Run Derby and All-Star Game).

Four of Baltimore¡¯s top Draft picks in Mike Elias¡¯ tenure as general manager (since November 2018) led the way to victory:

• Cowser (24 years old, ¡®21 first-round pick) went 2-for-4 with a walk and three runs scored.
• Henderson (23, ¡®19 second-round pick) went 3-for-4 with a homer, two RBIs, one walk and three runs scored.
• Adley Rutschman (26, ¡®19 first-round pick) went 2-for-4 with one double and three RBIs.
• Holliday (20, ¡®22 first-round pick) went 2-for-4 with a homer, one RBI, one walk and one run scored.

"You make a bad pitch, they're gonna hit it,¡± Williams said. ¡°Even the good pitches you make, they're gonna put the bat on the ball."

So together, the quartet of young stars collectively went 9-for-16 with one double, two homers, six RBIs, three walks and seven runs scored.

¡°A lot of us love to come out here and just play the game, and it was just a matter of time before we¡¯re all starting to get it clicking again,¡± Henderson said. ¡°Looking forward to seeing where it goes.¡±

The Orioles¡¯ offense will become even more dangerous once fellow youngster Coby Mayo (the club¡¯s No. 3 prospect and No. 15 overall in baseball) gets going.

Mayo, who was called up for the first time Friday, went 0-for-9 with two walks and five strikeouts over the first three games of the 22-year-old¡¯s big league career. Nobody is worried, though.

¡°Every player who¡¯s come up, they always hit some type of struggle,¡± Henderson said. ¡°It just depends on when.¡±

After all, Holliday is proof that playing in the Majors isn¡¯t easy. But eventually, those with immense talent will figure it out and become more relaxed, as he¡¯s doing now.

¡°I know he¡¯s going to be one of the great players,¡± said recent acquisition Eloy Jim¨¦nez, who went 3-for-5 on Sunday to improve to 5-for-9 with the O¡¯s. ¡°He¡¯s been putting in the work, and he¡¯s just so young. He¡¯s going to find his rhythm, and I know he¡¯s going to have success.¡±
