Arizona Diamondbacks vs. San Diego Padres preview
The Padres arrive in Phoenix desperately clinging to that final Wild Card spot, just one game ahead of the Mets and three behind the Dodgers in what's shaping up to be a brutal NL West race.
Arizona has quietly won three straight and holds a 3-1 season series advantage after Monday's 6-2 victory, with Corbin Carroll and Ketel Marte providing the offensive punch even after trading away Eugenio Suarez.
This pitching matchup screams trouble for both sides - Nestor Cortes hasn't seen game action since April 3rd and will be making his Padres debut, while Anthony DeSclafani lasted just 2.1 innings in his last outing.
The Diamondbacks might be eight games out of the Wild Card, but they're not rolling over, especially with Carroll's 22 homers leading a lineup that can still put up runs in bunches.
San Diego's Fernando Tatis Jr. and Manny Machado need to get something going after managing just two runs in the series opener, particularly with their playoff hopes hanging by a thread.
With both starters sporting ERAs north of 4.90 and question marks about their readiness, this could turn into the kind of offensive slugfest that favors whichever bullpen can hold things together longest.
