Giants manager Bob Melvin said Wednesday that he expects Doval to be recalled from Triple-A Sacramento sometime during the team's Aug. 23-29 road trip, Alex Pavlovic of NBC Sports Bay Area reports.

What role Doval would fill has not yet been determined, as Ryan Walker has been excellent since taking over the closer role. Since being demoted to Sacramento, Doval has allowed two runs with a 5:1 K:BB over four innings of work. Just one free pass is encouraging to see, as Doval's 13.3 percent walk rate was a major reason why the Giants opted to send him down. When the former closer does rejoin the big-league bullpen, he could work in low-leverage spots initially.
