Two of baseball’s top young bats left the yard on Thursday night and did so in thunderous fashion.

Seattle’s Taylor Trammell provided the only run in his team’s win – and preserved it with a game-ending catch -- while White Sox slugger Yermín Mercedes belted another mammoth blast in Chicago’s doubleheader sweep.

Trammell was the star of the Mariners’ 1-0 win in Houston. Leading off the third inning, Seattle’s No. 6 prospect connected on his fourth home run of the season to right-center, depositing it 359 feet over the wall according to Statcast data

It was the outfielder’s only hit of the night and one of just six combined for the game, four on Seattle’s side.

With the M’s clinging to the narrowest of leads with two outs in the ninth and the potential tying run on first base, Trammell raced in from deep center to make a sliding catch on a blooper off the bat of Carlos Correa for the game’s final out.

In Chicago, with a 3-1 win in the day’s first of two already under his team’s belts, Mercedes kept his eye-popping rookie campaign rolling. The designated hitter in an 11-0 rout in the nightcap, Mercedes mashed his fifth home run of the season to center field as part of a seven-run White Sox fifth. The blast left Mercedes’ bat at 110.8 mph and traveled 449 feet according to Statcast.

The No. 20 White Sox prospect is now batting .423/.464/.679 in 21 games this season.
