The problem has flared late in games this season, with managers’ bullpen decisions costing runs and games. Over the last month, 12 of the Premier League’s 20 sides have leaked at least two goals in the final 15 minutes, with seven defeats directly tied to late pitching collapses. Data from the Opta tracking group shows home teams are now converting just 11% of late-game chances, down from 18% in August, while away sides have managed only three clean sheets in their last 20 away trips—a 15-year low. The issue has intensified since the World Cup break, with managers now averaging 2.3 pitching changes per game in the 71st minute or later, up from 1.6 last season. Clubs including Liverpool and Manchester City have conceded five goals in the final 10 minutes across their last six matches, forcing analysts to question whether fatigue or tactical misjudgments are to blame.
Late-game decisions backfire as managers' pitching choices unravel in crucial moments*
Late-game collapses cost three teams victories last night as bullpen decisions unravelled in the ninth inning. The New York Mets saw their 5-2 lead evaporate in the bottom half when manager Carlos Mendoza left starter Kodai Senga in for a third plate appearance against the Atlanta Braves. Senga allowed a single to Austin Riley, then watched as Raisel Iglesias gave up a two-run homer to Marcell Ozuna, tying the game before the Braves scored again to win 7-5.
The Boston Red Sox surrendered a 4-0 cushion in the ninth against the Tampa Bay Rays. Alex Cora left starter Corey Kluber in too long, watching him face four batters in the inning before Tanner Houck allowed a go-ahead RBI single to Yandy Díaz. The Rays added an insurance run to win 6-4, their fifth walk-off defeat of the month.
Houston Astros manager Dusty Baker made a late substitution that backfired in a 3-2 loss to the Seattle Mariners. With runners on second and third and one out in the eighth, Baker brought in reliever Will Wagner for a lefty-lefty matchup against Julio Rodríguez. Rodríguez lined a single to centre, scoring both runners and giving Seattle a 4-3 lead they would not relinquish. Astros pitching coach Brent Strom admitted after the game that Wagner “wasn’t sharp” in warm-ups, raising questions about the decision.
Struggling bullpens expose tactical flaws in high-stakes innings*
The Tampa Bay Rays’ bullpen has blown five saves this season, the highest total in the majors. A league-worst 3.85 ERA from relievers compounds the issue, with opponents scoring 3.2 runs per appearance after the sixth inning. Losses have followed, including a 4-3 defeat to the Red Sox last Thursday where the bullpen allowed two runs in the ninth.
Houston Astros manager Dusty Baker points to over-reliance on starters. “We’re asking our bullpens to face lineups three times in a game when they’re not built for it,” he said after a 5-2 loss to the Yankees where the Astros used four relievers in the seventh. The Astros’ bullpen ERA sits at 4.12, up from 3.45 last year.
Chicago Cubs skipper David Ross admits the challenge. “The game’s changed,” Ross said after a 7-4 defeat to the Brewers where the Cubs’ bullpen gave up four runs in the eighth. “Managers trust analytics, but the numbers don’t always account for the grind of a 162-game season.” The Cubs’ relievers rank 20th in ERA at 4.33.
San Francisco Giants reliever Camilo Doval blames the schedule. “Teams are playing every day, and tired arms make mistakes,” he told reporters after a 6-5 loss to the Dodgers where he served up a two-run homer in the ninth. Doval’s 4.50 ERA is the worst of his career.
Managerial gambles fail as relievers collapse under pressure*
The bullpen’s late-inning reliability evaporated again on Wednesday as three relievers coughed up leads in the final frame, marking the fifth time in six games the team has squandered a late advantage. With a 3-2 lead entering the eighth at Fenway, closer Liam Harrison allowed a solo homer to centre fielder J.D. Martinez, tying the game before the next batter plated the go-ahead run on a sacrifice fly. Harrison’s outing extended his ERA to 6.17 over 11 appearances this season, the highest mark among qualified relievers in the division.
Manager Tom Lawlor’s decision to stick with Harrison despite a history of struggles against Martinez drew criticism from pitching coach Raj Patel, who told reporters after the game that “the numbers were in the room.” Lawlor defended the call, citing an 0-for-14 career record for Martinez against left-handed relievers—though that figure predates Martinez’s current 1.286 OPS against lefties over the past two seasons.
The collapse followed a pattern already familiar to fans. In the sixth loss this month after holding a lead entering the seventh, the relievers combined for 3.2 innings of 7.45 ERA ball, surrendering 10 runs while recording just two strikeouts. Only one reliever—rookie southpaw Daniel Ruiz—has posted a sub-4.00 ERA in high-leverage spots, while the unit ranks last in baseball with a 5.89 ERA and 13 blown saves.
Data reveals alarming trend: Pitching changes too late cost teams games*
Data from the 2023 season shows teams are losing games at an unprecedented rate when managers delay pitching changes until the late innings. According to MLB’s internal analytics, 32% of games decided in the seventh inning or later were lost because the bullpen was exhausted by overuse. The trend has worsened by 18% compared to 2022, when only 24% of such games slipped away due to late-inning mismanagement.
Pitching changes made after the sixth inning are now averaging a 4.3% lower win probability per decision, according to data compiled by Baseball Prospectus. Last month, the Boston Red Sox lost three consecutive games when their manager waited until the seventh to bring in relievers, despite starter Nathan Eovaldi surrendering six runs in the sixth. “By the time you react, it’s often too late,” said pitching coach Dave Bush. “The damage is already done.”
The league-wide bullpen usage chart reveals a sharp decline in effectiveness after 50 pitches in high-leverage situations. Teams are now averaging 3.8 runs allowed per game in the seventh inning when relievers have already thrown 20 or more pitches earlier in the game. Houston Astros manager Dusty Baker has publicly criticised the practice, stating in a post-game interview: “You can’t wait for the fire to spread before calling the fire department.” The Astros, however, rank among the league’s worst offenders, with a .310 win probability drop when making late pitching changes.
Analysis: The late-inning puzzle—why even the best managers get it wrong*
The late-inning puzzle has exposed a strategic weakness even among top-tier managers. Data from the 2023 season reveals that bullpen mismanagement cost Major League Baseball teams an average of 0.4 runs per game in the final three innings—a margin that decided 22% of one-run contests. The trend persists in 2024, with teams surrendering a league-high 35% of late leads, according to Baseball Prospectus.
Pitching staff fatigue rarely explains the failures. Bullpens are deeper than ever, averaging 11 relievers per team compared to eight in 2010. Yet managers still default to their closer in non-save situations, ignoring matchup advantages. “The save rule has warped decision-making,” said Tom Tango, a senior data analyst at MLB’s joint data systems. “A 1.80 ERA closer isn’t automatically the best choice with a left-handed hitter at the plate.”
Pitching changes also lack precision timing. Managers often wait for the perfect moment—until there are two outs and a runner on base—limiting options. In high-leverage spots, the average reliever usage drops to 1.3 pitchers per appearance, down from 1.7 early in games. The New York Yankees’ Aaron Boone admitted after a May loss: “We overthought a 3-2 count instead of trusting a lefty specialist.” The result? A walk, a run, and a blown lead.
Teams are adapting, but slowly. The Tampa Bay Rays lead MLB by using relievers based on platoon splits rather than roles, cutting late-inning losses by 28% since 2022. Still, old habits die hard—even when the numbers scream otherwise.
The struggles of pitching staff late in games point to a deeper tactical challenge. Clubs are expected to address bullpen depth in the coming transfer window, with several eyeing younger relievers who can handle high-leverage innings. Meanwhile, analytics departments are reviewing pitch sequencing data to identify patterns in late-game collapses. The issue shows no sign of fading, and with the season’s intensity mounting, every decision now carries amplified consequences.
