"Fans certainly have a right to voice their frustrations," Roberts said, according to ESPN.com's Alden Gonzalez. "I get that. But I do believe that this guy, born and raised as a Dodger, what he does -- he cares about the Dodgers, the fan base, and he's shown that on the field, off the field.
"He was looking forward to pitching at home. And so for it to not go well -- yeah, I'm disappointed to hear [the boos]. Certainly. He's not gonna say it, but I am."
Jansen, who entered the game with the Dodgers leading 2-1, allowed five of the six batters he faced to reach base. That stretch included a leadoff single by Buster Posey and a two-run home-run by Wilmer Flores that put the Giants up by a 3-2 margin. San Francisco went on to win, 4-2, and stretch its division lead over L.A. to two games. Jansen would depart in favor of Víctor González after loading the bases with two consecutive walks.
Overall, Jansen's line on the night read as follows: ⅓ inning pitched, three hits, three earned runs, two walks, and one strikeout.
Jansen had also blown the save in his first outing of the second half, with that coming last Sunday against the Colorado Rockies. In that appearance, he gave up a run on two hits. The Dodgers would subsequently lose to the Rockies in extra innings.
Even after Wednesday's loss, Jansen still has only a 2.15 ERA on the season. His performance has slipped in some other meaningful ways, as his strikeout and walk rates have both decayed from last season. On a per-nine basis, he's recording two fewer strikeouts and two more walks than he did in 2020, resulting in a 1.75 strikeout-to-walk ratio that would be a career-worst.
The Dodgers will conclude their four-game set against the Giants on Thursday with the hopes of splitting the series.
