Armstrong, a redshirt senior who transferred from UT Arlington, blasted three grand slams in the Bears' season‑opener against New Mexico State, the only other player to hit three in a game being Louisville's Jim LaFountain in 1976.
The first homer came on a low curveball in the third inning, the second on an inside fastball in the fourth, and the third on a high fastball in the seventh, all landing in left field. Armstrong finished the game 4‑for‑5 with 12 RBI, a hit‑by‑pitch, and a .750 batting average and 3.000 slugging percentage in his first Baylor game.
