Justin Verlander, pitching for the San Francisco Giants in the 2025 MLB season, has yet to secure a win despite starting 15 games. His most recent outing ended in a 13-0 loss to the Philadelphia Phillies at Oracle Park, where he allowed only two earned runs over six innings but was hampered by the Giants' bullpen and defensive errors. Verlander's losing streak includes an 11-2 defeat to the Sacramento A's and a 5-2 loss to the Chicago White Sox, where the bullpen surrendered a 2-1 lead in the seventh inning. Despite his personal performance, including a fastball velocity reaching 97 mph and 7 strikeouts in one game, the Giants' overall struggles have prevented him from recording a win. Historically, only Matt Keough in 1979 and Carl Morton in 1976 had 15 or more starts without a win before the All-Star break, highlighting the rarity of Verlander's current streak.
