LOS ANGELES — If the nine Dodgers pitchers on the injured list, Brock Stewart is the closest one to returning to the majors. But up first for the veteran right-hander is a minor league rehab assignment, which starts Tuesday night for the Class-A Ontario Tower Buzzers, about 42 miles east of Dodger Stadium.

Stewart had right shoulder debridement surgery last September 25, after pitching only four games for Los Angeles since getting acquired from the Minnesota Twins at the trade deadline on July 31. He began the season on the 15-day injured list.

Stewart resumed throwing late in spring training, and threw a simulated game at Dodger Stadium on March 27, during the first homestand of the season, before continuing to rehab at Camelback Ranch in Arizona. Pitchers are allowed up to 30 days on a minor league rehab assignment, and Stewart will probably need the majority of that time to build back up a number of games before getting activated.

“You’re sort of looking at a spring training, and how many outings a reliever takes,” manager Dave Roberts said Tuesday, “That’s probably what it’s going to take.”

A few veterans who got off to late starts in Cactus League play during spring training might have something close to the template Stewart might follow on his rehab assignment. Tanner Scott’s first game in camp was February 28, and he pitched 10 games in 24 days. Blake Treinen’s first game was February 26, and he pitched nine games in 25 days.

As for whom Stewart might replace in the Dodgers bullpen, there’s still plenty of time to work that out. Will Klein (1.17 ERA, 2.02 xERA in 7 2/3 innings) and Edgardo Henriquez (5.40 ERA, 3.71 xERA in five innings) have done pretty well but have also pitched in the lowest-leverage innings, on average, relative to the rest of the relief corps. Ben Casparius was pitching in nearly league-average leverage before getting placed on the injured list on Monday, with Kyle Hurt called up from Triple-A Oklahoma City.

“When he gets closer, certainly that will be a conversation. I hope we have that, it means everyone is healthy and then hopefully it’s a tough conversation,” Roberts said. “With [Stewart] being out, with other guys being out, it’s a good opportunity to see some guys. I’m happy Kyle Hurt is here, and obviously we get a longer look at Edgardo and guys like that.”
