San Diego PadresSan Francisco Giants

The San Diego Padres are off to a sluggish start this season, going 1-3 while scoring a total of just nine runs.

The Padres were shut out for the first 8.2 innings on Monday night against the San Francisco Giants before a Jackson Merrill two-run home run saved them from embarrassment. Things won't get any easier on Tuesday with the Giants' ace on the mound.

Padres vs Giants Pitching Matchup on Tuesday

The Giants have right-handed pitcher Logan Webb taking the mound on Tuesday night in San Diego. The right-hander struggled in his 2026 debut on Opening Night against the New York Yankees, allowing six earned runs across five innings with seven strikeouts.

Last year, he had a 3.22 ERA and 224 strikeouts across 207 innings, finishing fourth in National League Cy Young voting.

In his career at Petco Park, he's made seven starts, sporting a 4.38 ERA.

As for the Padres, right-hander Germán Márquez is getting set to make his team debut. Márquez spent the first 10 years of his career with the Colorado Rockies, but has struggled since his 2023 Tommy John surgery.

He made 26 starts last season, sporting a 6.70 ERA across 126.1 innings pitched. The Padres signed him to a major league contract in February, hoping they could get him back on track out of Coors Field and in a much more pitcher-friendly ballpark in San Diego.

Márquez has made 12 appearances (11 starts) at Petco Park in his career, sporting a 4.88 ERA across 66.1 innings.
