Padres 7, Diamondbacks 2

Batter’s box: Fernando Tatis Jr. blasted a 441-foot grand slam to the grassy hill beyond left field in a five-run second inning. Tatis also singled in his first at-bat and walked his final time up. … Trent Grisham scored the Padres’ first run on a delayed steal of home. He sprinted to the plate when Diamondbacks catcher Daulton Varsho threw to second in a failed attempt to get Tatis stealing. … Austin Nola drove in Jake Cronenworth with his second double of the spring. … Shortstop CJ Abrams, the team’s top position prospect, crushed a fly ball to the deepest part of the field in right-center and sprinted around the bases for a stand-up triple. He scored on Nick Tanielu's sacrifice fly.

Balls and strikes: Left-hander Ryan Weathers, the organization’s fifth-ranked prospect, started and allowed a run on two hits and a walk in his two innings. He got his final two outs with strikeouts. … Michel Baez also allowed a run in his two innings, fairly minimal damage considering the three hits and three walks he yielded. … Miguel Díaz, who in 2018 struck out 30 batters in 182⁄3 innings but hasn’t pitched in the majors since due to knee injuries, struck out two of the three batters he faced in the seventh inning and allowed a single in a scoreless eighth. ... Lefty Aaron Leasher, the Padres' sixth-round draft pick in 2017, threw two hitless innings.

Extra bases: The Padres fielded a primetime lineup Tuesday after the majority of Monday’s lineup consisted of backups and non-roster players. The only nonregular among Tuesday’s starting nine was catcher Juan Fernandez. Nola served as designated hitter. … Highly rated prospects Robert Hassell III and Abrams have played in all three games this spring. So has Rancho Bernardo High alum Gosuke Katoh. ... The game was shortened to eight innings.

On deck: Left-hander Blake Snell is scheduled to make his Padres debut today, facing the Brewers at 12:10 p.m. at Peoria Stadium (Fox Sports San Diego will televise).
