Gurriel went 2-for-4 with a sixth-inning grand slam in Houston's 7-2 win over Miami on Monday.
Gurriel won't generate home runs like a prototypical first baseman; he averaged 16.6 homers in 15 seasons in Cuba. His swing is tailored more to gap power, but he'll run into about a dozen or so during a season. Monday's bomb was his third of the season and sixth in 70 games since coming to the States.
