An industry source confirmed the deal, which has not been reported by the club. Kontos, who earned $517,500 last year, filed for $1.35 million. The Giants offered $850,000 -- which made this a mini-triumph for Kontos, since the Giants went beyond the $1.1 million midpoint.
Kontos, 30, enjoyed his best big league season last year, finishing 4-4 with a 2.33 ERA in a career-high 73 relief appearances. His 0.941 WHIP was a personal low, and he stranded his first 26 inherited runners before allowing his first such runner to score. That occurred July 24 against Oakland.
Kontos also limited right-handed batters to a .205 batting average. Opponents hit .159 (13-for-82) off him with runners in scoring position and .073 (3-for-41) with runners in scoring position and two outs. The only relievers in the Majors who were harder to hit with men in scoring position (minimum 75 at-bats) were Dellin Betances of the Yankees (.115) and Hector Rondon of the Cubs (.143).
Belt filed for $7.5 million, more than doubling the $3.6 million he earned last season. The Giants offered him $5.3 million. Talks are expected to continue until a hearing before an arbitration panel is held, no later than Feb. 21. At the hearing, each side presents its case to the panel, which selects one of the salary figures.
