After a promising debut in 2023, Walker made the Giants' Opening Day bullpen last season. The 28-year-old quickly worked his way up the high-leverage ladder, primarily pitching as a setup man until closer Camilo Doval was demoted to the minors. By that point, Walker became manager Bob Melvin's most trusted reliever and was elevated to the closer role in mid-August. By the end of the season, he was the only reliever to record double-digit wins (10), saves (10) and holds (21). Capping off an impressive breakout campaign, Walker was near the top of the leaderboard in several categories among relievers, including ERA (1.94, 12th), WHIP (0.85, 10th) and innings pitched (80, 7th). His 26.9 K-BB percentage ranked 10th and he finished one strikeout shy of 100. Unless San Francisco signs or trades for a more established closer this offseason, Walker enters 2025 as the clear favorite for saves in the Bay Area. Read Past Outlooks
