Jon Lester landed one of the biggest pitching contracts of his era when the Chicago Cubs signed him on December 15, 2014. The deal: 6 years, $155 million fully guaranteed. The return on investment came fast — Lester was a central piece of the Cubs rotation that ended a 108-year championship drought by winning the 2016 World Series.
His Biggest Contract, Broken Down
- Team: Chicago Cubs
- Signed: December 15, 2014
- Length: 6 years (2015–2020)
- Total guaranteed value: $155 million
- Average annual value: $25.8 million
- Signing bonus: $30 million
The $155 million was spread across the 2015–2020 seasons, averaging $25.8 million per year. Lester also received a $30 million signing bonus up front, putting a significant chunk of money in his pocket from day one.
The contract included a mutual option for 2021 worth $25 million, with a $10 million buyout. Either side could exercise it — neither did, and the deal closed exactly as written.
What «Fully Guaranteed» Actually Means
In MLB, a fully guaranteed contract means the player gets paid every dollar on the books regardless of injuries, performance, or roster moves. Lester’s $155 million was completely protected — the Cubs couldn’t cut him or reduce his salary. The only conditional element was the 2021 mutual option, which was never triggered.
Where Lester Ranks Among the Highest-Paid Pitchers
- Ranking among pitchers: #20 (by total guaranteed value)
At $25.8 million per year, Lester ranked 20th among the highest-paid pitchers of his era. Not the top of the list, but firmly in the upper tier — a signal that the Cubs viewed him as a true rotation anchor capable of leading a team through a championship run. That bet paid off.

What He Earned Before Chicago
| Team | Years | Value | Type |
|---|---|---|---|
| Boston Red Sox | 2009–2013 | $30 million | Extension |
Before the Cubs came calling, Lester had already built a solid earnings track record in Boston. His $30 million extension with the Red Sox covering 2009–2013 established his market value. By the time he hit free agency in December 2014, Lester was a 30-year-old ace with two World Series rings (2007 and 2013) and an elite résumé. The Cubs outbid the competition and got their man.
The jump from his Boston extension to the $155 million Cubs deal was dramatic — and it reflected both Lester’s growth as a pitcher and Chicago’s willingness to spend big to end their historic drought.
