Blows save chance
PArizona Diamondbacks
July 22, 2024
Martinez allowed one run on two hits and one walk in the ninth inning Sunday, blowing the save in a 2-1 extra-inning loss to the Cubs.
ANALYSIS
With closer Paul Sewald unavailable to protect a ninth-inning lead after having being deployed the previous two days, manager Torey Lovullo turned to Martinez, who was also used Friday and Saturday but had thrown fewer pitches (25) than Sewald (33). Martinez, facing the same group of hitters he shut down Saturday, allowed a double to Nico Hoerner and a single to Seiya Suzuki, permitting the lead to slip away. The rookie right-hander has worked his way into a high-leverage role this season and could eventually become a late-game staple.
