TAMPA, Fla. — The Dodgers didn’t go shopping at the top of the market ahead of Thursday’s trade deadline.

But what they came away with — right-handed relievers Brock Stewart and Paul Gervase to bolster the bullpen, and versatile outfielder Alex Call to round out the lineup — are the kind of moves that “just raises the floor for our ballclub,” manager Dave Roberts said Friday.

“I feel we did get better,” Roberts said, before echoing the front office’s hope that the Dodgers’ biggest improvements over the final two months of the season come from the star-studded, but underperforming, core they already have in place.

“I think we’ve got a pretty dang good team. I think if you look at it from the offensive side, as far as our guys, they’ll be the first to tell you they’ve got to perform better and more consistently. That’s something that we’re all counting on … I love our club. I really do. Now it’s up to all of us to go out there and do our jobs.”

The job for the Dodgers’ two biggest acquisitions, Stewart and Call, will be clear from the get-go.

Stewart, a former Dodgers swingman from 2016 to 2019, has reinvented himself in the second half of his career. Unlike his first stint in Los Angeles, when he threw in the low 90s and was a fringe long reliever on the roster, Stewart is now a higher-leverage relief option, with a mid-to-upper 90s fastball and swing-and-miss sweeper he has used to dominate right-handed hitters this season.

“At the end [of his first Dodgers stint], he lost the velocity and was trying to figure out if he could hang on and who he was at that point,” Roberts recalled. “Obviously, he’s put in a ton of work to sort of find himself again. He’s had nothing but success. I’m excited to see this version of him. He certainly shouldn’t lack for confidence.”

Stewart won’t fix the Dodgers’ ninth-inning problems — with their closer role up in the air ever since struggling offseason signing Tanner Scott went on the injured list with an elbow injury — but could get some save situations “in the right situation,” Roberts said — for instance, if a run of right-handed hitters (who are batting just .104 with a .327. OPS against him this year) are up at the end of the game.

“I trust the guy, I trust the player, what he’s become,” Roberts said. “So for me, if the situation calls for it tonight and he’s in the ninth inning, I’ve got all the confidence.”

Gervase, a 6-foot-10 right-hander the Dodgers acquired from the Tampa Bay Rays in exchange for catcher Hunter Feduccia as part of a three-team trade on Wednesday night, was also on the active roster Friday. He comes with just five previous career MLB appearances, but a deceptive delivery aided by his long-limbed extension on the mound.

“I don’t know a whole lot about him,” Roberts said. “I know he’s got a big arm. He’s got some extension, some rise, but I haven’t seen him.”

The arrival of Stewart and Gervase did coincide with yet another loss in the bullpen. Veteran right-hander Kirby Yates, another offseason signing who has disappointed with a 4.31 ERA this season, was placed on the injured list because of lingering discomfort in his pelvic and lower-back area. He went back to Los Angeles to get further testing.

“In the last, call it, two weeks, he hasn’t felt great,” Roberts said. “Hasn’t been injured, in his words, which is why he kept pitching and competing. But we flew him home this morning to look at the doctor and kind of get some tests to see if there’s something that’s kind of been aggravating him. Something’s just not right, exactly. So we’re trying to suss that out.”

In the lineup, Roberts said Call — a 30-year-old right-handed-hitting journeyman who found a niche with the Washington Nationals the last few seasons as an on-base threat capable of grinding out tough at-bats — would mix in at all three outfield spots.

“[He is] a tough, feisty hitter,” Roberts said. “I certainly see him playing versus left. But I think he’s pretty much a neutral guy. Slugs a little more against left, but gets on base against right. I’m going to try to keep him in there a couple times a week.”

Call said he wasn’t shocked to learn he had been traded on Thursday, and was excited by the “chance to compete in the playoffs and win a World Series” with a first-place Dodgers team.

“For me, I am going to grind out at-bats, put the ball in play, take my walks, make it tough on the pitcher,” said Call, who has hit .297 with the Nationals in 102 games over the last two seasons. “Just really make the [pitchers] work so that hopefully they’re tired when the top of the order comes back around or whatever.”

Roki Sasaki facing hitters

Internally, the Dodgers are hoping rookie Japanese pitcher Roki Sasaki can also serve as a de facto late-season addition after missing the last several months with a shoulder injury.

And this week, the right-hander took a key step in his recovery process.

Sasaki faced hitters for the first time since getting hurt in a simulated inning this past week in Arizona, Roberts said, and is scheduled to throw two more simulated innings on Saturday.

The team has been targeting a late-August return for Sasaki, who had a 4.72 ERA in eight starts this season before going on the IL.
