2025 Fantasy Outlook
Martinez struggled in his first exposure to the big leagues in 2023 and failed to break camp with the Diamondbacks last spring. The 23-year-old missed plenty of bats in the minors, striking out 14 across 6.2 innings for Triple-A Reno last year before his recall in late-April. Martinez still had trouble throwing strikes in the majors, but worked around his 11.7 percent walk rate to produce a solid 2.48 ERA over 72.2 innings. The flamethrower walked 36 to inflate his WHIP (1.31), but his splitter was absolutely devastating (.098 BAA, .122 SLG), generating a 54 percent whiff rate that was 3rd-highest in the league for that pitch type. He also averaged 100.3 mph on his sinker while inducing ground balls at a 60 percent clip. Martinez's ascension to the back-end of Arizona's bullpen was no surprise and he racked up eight of the team's 13 saves after Aug 1. He enters 2025 as the presumed favorite for saves in Arizona, but closing is no guarantee due to the traffic he allows. Read Past Outlooks
Enters in seventh inning
Martinez allowed one run on three hits and one walk while striking out two over 1.1 innings in Wednesday's 8-2 win over the Giants.
ANALYSIS
The Diamondbacks were up, 5-1, when manager Torey Lovullo had Martinez enter the contest to open the seventh inning. He allowed the first two batters to reach but managed to wriggle out of danger. The right-hander was sent out to start the eighth and was removed after a double and single made it a 5-2 game. It's unclear why Lovullo had his closer enter what would normally be a low-leverage spot. Martinez has pitched at regular intervals over the past week, so it wasn't an issue of rust. Perhaps it was due to Lovullo's desire to end the team's three-game losing skid.
