Late-Career Closers and Early Returns: A Familiar Tigers Pattern

Late-Career Closers and Early Returns: A Familiar Tigers Pattern

The Detroit Tigers have been here before.

Kenley Jansen’s first month in Detroit — three blown saves and an ERA above six — has brought early volatility to the back end of the bullpen. But within the organization’s recent history, that type of start is not unusual when it comes to veteran closers signed late in their careers.

Joe Nathan and Francisco Rodríguez followed similar paths when they arrived in Detroit.

Nathan, signed ahead of the 2014 season at age 39, converted 35 of 42 save opportunities — an 83.3 percent save rate — but finished with a 4.81 ERA and seven blown saves, the highest total of his career. Rodríguez’s 2016 season produced 44 saves with a 3.24 ERA, but with similar inconsistency in run prevention compared to his peak seasons.

In both cases, the Tigers received production in the form of saves, but not the same level of efficiency.

Jansen entered his Tigers tenure with a stronger recent baseline. In 2025, he posted a 2.59 ERA with 29 saves across 62 appearances, continuing a stretch of sustained production into his late 30s. Over a broader sample since 2021, he has maintained a 3.06 ERA with more than 160 saves, reflecting continued durability and strikeout ability.

The early results in Detroit, however, align more closely with the Tigers’ previous experiences than with Jansen’s recent track record.

The Statcast data provides context.

Jansen’s cutter — still his primary pitch — continues to sit in the 92–93 mph range, consistent with prior seasons. The pitch characteristics remain intact. In 2025, opponents hit just .164 with a .302 slugging percentage against the cutter, supported by a whiff rate above 25 percent and usage exceeding 80 percent.

That profile has not fundamentally changed.

What has changed is the outcome when hitters make contact.

Through the first month of 2026, opponents are producing significantly higher results against the pitch, with increases in both batting average and slugging percentage. The expected metrics align with those results, indicating that the shift is tied to contact quality rather than variance alone.

The hard-contact data adds another layer.

Jansen’s cutter produced a 46.8 percent hard-hit rate in 2025, a relatively high figure that was offset by weak outcomes and limited damage. Early in 2026, that hard-hit rate has dropped, but the results have moved in the opposite direction — higher average, higher slugging, and more extra-base damage.
