Lincecum pitched to an ERA of 4.54 in the second half of the 2013 season; however, the Giants bullpen accounted for an unusually high 12 earned runs charged to Lincecum. In 32 starts in 2013, Lincecum went 10–14 with a 4.37 ERA, striking out 193 in innings. By the end of the year, he had 1,510 strikeouts, the third-highest total by a pitcher over his first seven years (behind Tom Seaver's 1,655 and Bert Blyleven's 1,546). On October 22, Lincecum signed a two-year, $35 million contract, which prevented him from becoming a free agent.
