Alex Kirilloff’s first big league homer came on Friday. Now, big flies are coming in bunches.

After starting his Major League career hitless through his first five games, baseball’s No. 21 prospect is coming on strong. Kirilloff extended a young hitting streak to six straight by hammering his fourth home run in three games on Sunday afternoon, adding the final three runs to his team’s tally as Minnesota routed Kansas City, 13-4.

Kirilloff was 0-for-14 before doubling for his first hit in the bigs on April 26. That sparked the 2016 first-round pick’s bat. Since, the outfielder/first baseman is 7-for-24 to boost his slash line to .184/.200/.526 after his slow start.

On Sunday, he provided the exclamation point on the Twins’ big day at the plate. Facing Kansas City reliever Jake Newberry, Kirilloff belted the first pitch he saw from the right-hander and deposited it into the second deck in right-center field. The blast left Kirilloff’s bat at 106.1 miles per hour and traveled 431 feet, according to Statcast.

Kirilloff finished the three-game weekend series against the Royals 4-for-12 with four homers, nine RBIs and four runs scored. The 23-year-old has now scored at least one run in four straight games during his current hitting streak.

More notable performances from rookies on Sunday:

Andrew Vaughn, LF, CWS (MLB No. 12)
The top-ranked White Sox prospect put up his third multi-hit game in his last six with two singles on Sunday afternoon. Vaughn lined a base hit to left field in the bottom of the fourth inning and bounced another into center in the ninth. With hits in seven of his last nine games, Vaughn has boosted his slash line from .136/.321/.227 entering play on April 17 to .275/.373/.373 after Sunday’s result. Gameday»
