When it comes to offseason moves, the size of the splash they make doesn’t always line up with the level of production that follows. And sometimes the best moves are ones that flew under the radar.

That’s certainly the case early in 2023. And while there is a long way to go this season -- and many of last winter’s deals will take even longer to fully evaluate -- let’s check in on how things are going thus far. For this task, we asked 10 MLB.com writers to draft the acquisitions (via signing or trade) that have looked the best over the first several weeks of the season.

Keeping in mind that a number of the top 2022-23 free agents re-signed (including Aaron Judge, Clayton Kershaw, Brandon Nimmo and Anthony Rizzo), this pool is limited to those who changed teams.

1. Sean Murphy (Braves)
How acquired: Three-team trade with A’s and Brewers

The book on Murphy was pretty simple when this blockbuster was struck: a fabulous player behind the plate who provides an above-average bat. Defensively, Murphy has looked as advertised. Offensively, the 28-year-old has looked like Mike Piazza. Murphy entered this season with a career 115 OPS+. He’s currently at 160 in 2023. He is on pace for 37 homers; his career high is 18. His expected stats and barrel rates are all near the top of the scale. Suddenly one of the game’s most dangerous hitters, Murphy is a big reason why the Braves are once again atop the NL East.

2. Nathan Eovaldi (Rangers)
How acquired: Signed as a free agent (2 years, $34 million)

As we all expected, the Rangers added a staff ace in free agency. But as it turns out, they added two. Eovaldi has been a worthy co-ace with Jacob deGrom -- which has been even more important with the two-time Cy Young Award winner currently injured. Eovaldi has thrown 60 1/3 innings, and they’ve been great ones, with a 2.83 ERA. Prior to his last start, he had gone at least eight shutout innings in three straight starts, the longest such streak since Clayton Kershaw had four straight in 2015.

3. Brent Rooker (Athletics)
How acquired: Selected off waivers from Royals (Nov. 17, 2022)

The task is to pick the offseason acquisition whose performance has looked the best to this point in the season. With 11 homers and a .984 OPS, Rooker is hard to pass up. He’s unlikely to finish among MLB’s batting leaders, but he has shown enough that the A’s might have snagged -- off waivers! -- a potential building block (or enticing trade chip?) in the 28-year-old slugger. After all, Rooker has a pedigree (2017 first-round Draft pick), consistently hits the ball hard (top 10 in barrels per plate appearance and xwOBA) and is improving his plate discipline (14.3 percent walk rate).

-- Jason Catania

4. Luis Arraez (Marlins)
How acquired: Trade with Twins

In four seasons with the Twins, Arraez hit a remarkable .314, capturing the American League batting title with a .316 average in 2022. The Marlins paid a steep price to acquire him from Minnesota -- starter Pablo López and two prospects -- but Arraez has produced at a remarkable rate this season. He was batting over .400 as late as May 9, and is still hitting .388, leading the Majors in batting average and hitting for the Marlins’ first cycle along the way. Arraez’s .487 slugging percentage is a career-high mark for him, and he’s striking out less than 6 percent of the time. The man just flat-out hits.

5. Kevin Kiermaier (Blue Jays)
How acquired: Signed as a free agent (1 year, $9 million)

Kiermaier has been one of the savviest free-agent signings of this past offseason. The center field defense has been spectacular as usual; his 4 Outs Above Average entering Friday was tied for the MLB lead among outfielders. While he’s certainly overperformed offensively -- as of Friday, he had the fourth-largest gap between his wOBA and expected wOBA -- his 149 wRC+ is ninth-best among the 98 outfielders with 100+ plate appearances. Put it all together and his 1.6 WAR (FanGraphs) trails only 19 position players.

-- Brent Maguire

6. Dansby Swanson (Cubs)
How acquired: Signed as a free agent (7 years, $177 million)

Cubs infielders combined for -13 Outs Above Average in 2022, which ranked 26th in MLB. That alone made Swanson (+22 OAA in '22) a natural fit, and entering Friday, this year’s Cubs infield had the 2nd-most OAA in baseball (+13). Swanson is also maintaining a career-high .367 on-base percentage -- which has contributed to another huge shift for the Cubs, who boast the second-highest team OBP this season at .342, a 31-point increase from '22. Long story short, Swanson has been a major player in the trend towards a more refined and fundamentally sound brand of Cubs baseball. What’s not to like about that?

-- Shanthi Sepe-Chepuru

7. Xander Bogaerts (Padres)
How acquired: Signed as a free agent (11 years, $280 million)

The Padres' offense has been massively disappointing, but don't blame Bogaerts. The veteran shortstop has cooled off lately, but he put up big numbers in the opening weeks of the season, when the club was missing Fernando Tatis Jr. and Manny Machado's bat was nowhere to be found. Bogaerts hit .342 with a .953 OPS in the 20 games Tatis missed while finishing up his suspension.

Bogaerts is also having a fantastic season on defense, tying for first in the Majors in Outs Above Average entering play Friday. Meanwhile, Tatis has thrived at his new position in right field -- entering Friday, he ranked in the 89th percentile in OAA, the 98th percentile in outfielder jump and the 99th percentile in arm strength. With Bogaerts at short and Tatis in right, the Padres entered Friday leading MLB with 17 OAA.

-- Thomas Harrigan

8. Joey Gallo (Twins)
How acquired: Signed as a free agent (1 year, $11 million)

To say things didn’t work out for Gallo in 140 games as a Yankee would be an understatement -- and his 44 games as a Dodger late in 2022 didn’t help much. Still, it hadn’t been long since the 29-year-old was a highly productive player in Texas, and now he looks like that guy again. It’s not that Gallo has changed who he is. Rather, he’s simply back to mashing the ball like he did at his peak. Whether it’s more about escaping the Bronx, not having to worry about the shift or simply making some adjustments, it’s working. Gallo’s 142 wRC+ leads a first-place Twins club, and he has capably handled both first base and the corner outfield spots. 

-- Andrew Simon

9. Masataka Yoshida (Red Sox)
How acquired: Signed from NPB's Orix Buffaloes via posting system (5 years, $90 million)

Yoshida was an elite contact hitter and on-base machine in Japan; now he's an elite contact hitter and on-base machine in MLB. The lefty-swinging outfielder is one of nine qualified hitters with more walks than strikeouts this season. Yoshida is a top 25 hitter by batting average (.299) and on-base percentage (.378), and a top 40 hitter by slugging percentage (.493) and OPS (.871). What a great signing. Maybe he'll even be a dark-horse MVP candidate.

-- David Adler

10. Hunter Renfroe (Angels)
How acquired: Trade with Brewers

It seems Renfroe has taken this whole “Mike Trout lookalike” thing pretty seriously. Renfroe and Trout are both 31 years old. One is 6-foot-1, 230 pounds. The other is 6-foot-2, 235 pounds. And yes, their faces look a lot alike, too. But Renfroe appears to have decided that since he's now patrolling the same outfield as the three-time AL MVP, he might as well play more like him, too. 

Trout has 20 extra-base hits so far this season (10 homers) and Renfroe has 19 (10 homers). Renfroe’s hard-hit rate is a career-high 48.1 percent, while his walk rate is up over last season and his strikeout rate is down. He’s contributed defensively, too, with the latest example coming in the ninth inning Thursday, when he threw the Orioles’ Adam Frazier out trying to stretch a single into a double. The Angels held on to win, 6-5. Then he helped the Halos win Friday with the bat, going 3-for-4 with a go-ahead single in the seventh inning of a 5-4 victory over the Twins.
