The San Diego Padres return to Petco Park on Wednesday, July 29, hosting the Colorado Rockies for a 4:10 p.m. PT first pitch. The Padres have not announced a starting pitcher as of this writing, which is worth monitoring before game time, while Colorado will send right-hander Gabriel Hughes to the mound. San Diego rolls out a recognizable lineup built around Fernando Tatis Jr., Manny Machado, and Jackson Merrill — a core capable of doing damage against any arm in the National League West.

Padres vs. Rockies: Starting Pitcher Breakdown

Gabriel Hughes gets the ball for Colorado. The young right-hander is a name Padres fans should know — he was one of the key pieces Colorado has been building around in their rotation. Without current ERA or win-loss figures available, it's difficult to project exactly where Hughes stands this season, but the Padres' lineup will give any starter a legitimate stress test from the top of the order on down.

On the San Diego side, the starting pitcher slot remains open. That's a storyline to track. Whether it's an opener, a spot start, or a late roster move, the Padres' front office will need to fill that slot before first pitch. The bullpen depth and how the club manages innings will be a subplot to this game regardless of who gets the ball.

• 7. Gavin Sheets — DH
• 8. Xander Bogaerts — SS
• 9. Freddy Fermin — C

Keys to Watch at Petco Park

Tatis Sets the Tone Early

Fernando Tatis Jr. leading off is as electric as it gets at Petco Park. When he gets on base in the first inning, this lineup has the kind of run-producing middle of the order — Machado hitting third, France hitting cleanup — to capitalize immediately. Hughes will need to be sharp from pitch one.

Cronenworth in the Two-Hole

Jake Cronenworth batting second is a grind-it-out presence who keeps at-bats alive and puts the ball in play. His ability to work counts and make contact gives Tatis legitimate protection in front of the lineup's power.

Merrill and the Bottom Half

Jackson Merrill in center at fifth is a key production spot, and the combination of Rengifo, Sheets, and Bogaerts behind him means Hughes can't simply navigate around the top of the order and coast. The bottom third of this San Diego lineup has enough threat to punish a lack of command.

The Unknown Starter

Until the Padres announce who takes the mound, that is the biggest variable in this game. Colorado's lineup is capable of doing damage if San Diego's starter struggles with command or pitch count early. The bullpen may be asked to carry a significant load.

Prediction

The Padres have the lineup to make life uncomfortable for a young pitcher in Gabriel Hughes, and Petco Park's home atmosphere should provide a boost. San Diego's offense gets to Hughes early, and the bullpen holds the lead. Padres win, 5-3. The starting pitcher situation is the one legitimate concern, but back this lineup at home.
