Geraldo Perdomo

25-Year-Old ShortstopSS
Arizona Diamondbacks
2025 Fantasy Outlook
Perdomo, who went down with a knee injury in early April and missed two-plus months, had career-bests in average (.273), slugging (.374) and OPS (.718) over 98 games in 2024, but a deeper look reveals he exceeded expected rates. Ahh, the benefits of a favorable BABIP (.317), which also pumped up his wRC+ (101). He continues to exhibit elite plate discipline though his walk rate fell to 9.3%. Had the organization's plans for 2024 played out, prospect Jordan Lawlar would challenge Perdomo in 2025 or have been called up last year when Perdomo was out, but Lawlar had his own drama. He injured his thumb late in spring training, missed two months, then injured a hamstring and finished with just 14 games played outside of the Arizona Complex League. That means Perdomo is a lock to open the season as the starter at shortstop, but the organization is deep at the position. Read Past Outlooks

Swipes bag in win
SSArizona Diamondbacks
May 19, 2025
Perdomo went 1-for-3 with a stolen base in Sunday's 1-0 win over Colorado.
ANALYSIS
Perdomo extended a hit streak to six games with a second-inning single, after which he stole his 11th base over 46 games. That's two more than the shortstop had in 98 games last year, and he's threatening the career-high 16 swipes he posted in 2023 across 144 games. Perdomo is enjoying his most productive season since becoming a full-time starter in 2022.

No one in the National League with at least 70 plate appearances had a higher OPS in April than Perdomo's 1.073 mark, as the young infielder came storming out of the gates with a .383/.456/.617 batting line in his first 22 games. However, to say luck was on Perdomo's side that month would be an understatement. He had just a 14 percent hard-hit rate and a .237 xBA but benefitted from a bloated .477 BABIP during that stretch. Regression came hard from that point forward, with Perdomo slashing just .222/.337/.314 the rest of the way. The 24-year-old did rebound with a .275/.362/.392 line and a couple homers in the postseason, operating as the Diamondbacks' everyday shortstop in their surprise run to the NL pennant. Perdomo should enter 2024 with a leg up on the shortstop gig, but Jordan Lawlar is lurking and Eugenio Suarez is now at third base. He has a terrific eye at the plate with a career 11.6 percent walk rate, but Perdomo's quality of contact is so weak (19.5 percent hard-hit rate in 2023) that it's hard to see him as a long-term road block for Lawlar.
Perdomo posted the second lowest wRC+ among hitters with at least 500 plate appearances last season. He was thrust into a starting role when a shoulder injury limited Nick Ahmed to just 19 games and despite struggling, Arizona decided to use the season to give Perdomo on the job training. There was hope Perdomo would carry over the prior year's second half improvement, but it failed to manifest He only fanned 20.6% of the time, but a 3rd percentile average exit velocity and a 2nd percentile Hard Hit rate cratered Perdomo's batting average and power. Still just 23-years-old, Perdomo can continue to adjust and prove he can handle major league pitching, but with top shortstop prospect Jordan Lawlar on the fast track, Perdomo may only have this season to prove his worth. Unfortunately, there is nothing on which to hang a fantasy hat. Perdomo is a track and follow, only roster-worthy in the deepest of leagues.
Perdomo was so bad in a brief cup of coffee with the big club to start the year (1-for-13) and then after a demotion to Double-A (.151/.305/.204 slash line) that he was placed on the development list and sent to the team's spring training complex to rebuild his swing and get a mental reset midseason. He was a completely different hitter when he was activated in early August, hitting .329/.414/.521 with five home runs, six steals, a 20.7 K% and an 11.2 BB% in 38 games across Double-A and Triple-A. Perdomo was rewarded with another brief stint in the majors over the final week of the season, and he hit .333 with three doubles and one triple in 24 PA. He has always been seen as a glove-first shortstop, but the fact Perdomo has never walked at less than a 12% clip and has plus speed means that he could be an intriguing fantasy option if he is a leadoff hitter and not a No. 8 or 9 hitter. Nick Ahmed is under contract through the 2023 season, but he is not making so much money that he couldn't shift to a part-time role if Perdomo looks like the superior option at some point this season or next.
Perdomo doesn't have loud tools, but he has a career .411 OBP in the minors and is a lock to stick at shortstop, so he should have a long career. His tools play up due to excellent instincts. At 6-foot-3 and with a quick, whippy bat, he could eventually tap into 20-homer power, but we haven't seen that manifest yet. The switch hitter puts more of a charge into the ball from the left side. Perdomo, a 55-grade runner, relies on long strides and good instincts to steal bases. He was 20-for-28 on SB attempts at Low-A, but was 8-for-16 in the Cal League and Arizona Fall League. His defense will keep him in the lineup, and he could be a leadoff hitter with his plate discipline and potentially plus hit tool. Perdomo was limited by a minor foot injury during fall instructs. He turned 21 this offseason and already had success at High-A and the AFL, so he should open at Double-A and could move quickly to Triple-A.
Perdomo put on a clinic at Low-A, High-A and the Arizona Fall League, all as a 19-year-old switch hitter who will stick at shortstop. He had a slow start in the cold conditions of the Midwest League, but from the start of summer (June 21) on, he hit .309/.406/.398 with an 11.7 BB% and 14.9 K% across three levels. Power is not yet a big part of his game, but he is 6-foot-3 and generates plus bat speed with his whippy swing, so the expectation is that he will be a 25-homer guy once physically mature -- there are some similarities to Didi Gregorius with regards to size, defense and power upside. An above-average runner, Perdomo was 20-for-28 on SB attempts at Low-A, but was 8-for-16 in the Cal League and AFL. He could swipe 10-15 bases in his early years. His advanced approach and hit tool have him on a fast track, but he will probably face an adjustment period at some point in his age-20 season.
Perdomo emerged in rookie/short-season leagues late enough in the season that the hype surrounding him did not fully materialize until after he played his final game. He entered the year under the radar, as he only signed for $70,000 out of the Dominican Republic in 2016. A switch hitter whose defensive home is not set in stone, Perdomo has a projectable 6-foot-2, 184-pound frame and a whippy swing that should eventually generate 20-homer pop, primarily from the left side. He is at least a 55-grade runner and has good instincts on the bases, leading to 24 steals on 30 tries in 57 games. However, what will carry him to an everyday role in the big leagues will be his advanced approach and hit tool. He hits line drives and flyballs to all fields and logged a 44:39 K:BB in 257 PA across the AZL, Pioneer League and Northwest League. Perdomo will head to the Midwest League for his age-19 season where his stock could explode if he meets expectations.

Latest Fantasy Rumors
Good chance to make ASG
SSArizona Diamondbacks
May 21, 2025
Perdomo's start to the 2025 season has put him in a strong position to represent the National League at the All-Star Game, Jack Sommers of SI.com reports.
ANALYSIS
Perdomo leads all shortstops with a 2.6 WAR, and he's having a breakout year at the plate with a .307/.405/.494 slash line with 11 steals, six home runs and 37 RBI over 207 plate appearances. Sommers notes that playing in Arizona puts Perdomo at a disadvantage against shortstops in bigger markets and fanbases like Francisco Lindor and Mookie Betts. However, even if he's not selected as an NL starter, Perdomo has a great chance at making the roster via the player vote or commissioner's selection.
