The Arizona Diamondbacks intend to extend qualifying offers to left-handed starter Patrick Corbin and outfielder A.J. Pollock prior to Friday afternoon's deadline, according to Jon Heyman of Fancred Sports.

Both players have 10 days to accept or reject the $17.9-million offer. The Diamondbacks will receive compensatory draft picks in the 2019 amateur draft from the players' new teams should they sign elsewhere.

Corbin, 29, is widely seen as the best pitcher available on the free-agent market after going 11-7 with a 3.15 ERA and 246 strikeouts over 200 innings in 2018. He was also named to his second All-Star team in the process.

The oft-injured Pollock hit .257/.316/.484 with 21 home runs, 21 doubles, and 13 stolen bases in 113 games last season.
