JUPITER, Fla. — Top prospect Konnor Griffin homered for the third time this spring in the first inning of the Pittsburgh Pirates’ 6-1 victory over the St. Louis Cardinals on Sunday.

The Pirates have won eight of their 10 spring games.

The 19-year-old Griffin, ranked as MLB Pipeline’s No. 1 prospect, started at shortstop for the Pirates and hit a two-run shot off Kyle Leahy to give Pittsburgh a 2-0 lead.

Griffin went deep twice against Boston on Tuesday.

The Pirates drafted Griffin in the first round in 2024. He reached Double-A last year, where he hit .337 with a .960 OPS in 21 games for the Altoona Curve.

Jared Triolo went 2-for-3 with a double and two RBIs for the Pirates, and Jhostynxon Garcia went 2-for-2 with a solo home run.

Hunter Barco tossed three scoreless innings.

Cardinals manager Oliver Marmol signed a two-year contract extension through at least the 2028 season. The deal that was announced Sunday includes a club option for 2029.

On Saturday, Oneil Cruz hit a three-run home run in the fifth inning as the Pirates defeated the Houston Astros, 5-2, in a game called in the sixth inning due to rain.

Braxton Ashcraft started for Pittsburgh and allowed just one hit in three scoreless innings, and Marcell Ozuna went 2-for-3.
