After losing two of three to the Milwaukee Brewers on the road, the San Diego Padres arrived in Seattle with an offense that lacked thump, as well as production, from the top of the lineup. With Fernando Tatis Jr., Jackson Merrill, and Manny Machado scuffling, the rest of the roster carried the team to a sweep of the Mariners and a 28-18 record, a half-game back of the Dodgers in the NL West.
There is not much to say that is new about the problems the three faces of the franchise are experiencing. Over the 18 games from April 27 to May 16, Machado/Tatis/Merrill had a collective .164/.231/.249 batting line. The doubles that Machado and Merrill hit in Sunday’s game were the first extra-base hits they both had in the same game since April 11 (per Kevin Acee in Padres Daily newsletter).
Here is where the Padres offense stands as of the end of the Mariners series:
Batting average – .224, 30th OBP – .296, 28th SLG – .371, 26th OPS – .667, 28th
It doesn’t make sense that this team is 10 games over .500 and in second place in the NL West, but that is the case. As everyone in sports media keeps saying, this isn’t sustainable. Even manager Craig Stammen acknowledges that to be true.
Lucas Giolito
Padres president of baseball operations A.J. Preller signed right-handed starter Lucas Giolito to a $1.5 million contract for 2026 with a $1.5 million buyout for 2027 and escalators that could net him an additional $5 million. He signed on April 22 and his contract guaranteed a promotion to the major league team by May 16. He had two starts in Single-A and two starts in Double-A before debuted with the Padres on Sunday against the Mariners. After pitching five shutout innings with one hit allowed, Giolito sat for a prolonged half-inning while his teammates put up five runs in the top of the sixth inning.
In the bottom of the sixth, he was not the same guy. After walking three straight hitters, he was removed from the game and was then charged with the three runs scored by the Mariners after his departure. Giolitto got the win after his offense went on a hitting spree (especially Gavin Sheets) and put up eight runs for the game.
Giolito’s performance was all the more impressive considering he hasn’t had anything close to a normal ramp-up to the season. Going unsigned through the offseason and Spring Training, Giolito was on his own to prepare to pitch for a major league team. Staying unsigned until late April, his contract only gave him 23 days to prepare for his debut with the Padres.
His velocity was notably less than his normal 94-95 mph on his fastball (90-92), but his changeup is elite and makes the fastball a playable pitch. He throws those two pitches 85% of the time. In 145 innings pitched in 2025, Giolito threw to a 3.41 ERA, even though his underlying numbers don’t look that impressive.
With time spent working with Ruben Niebla and his staff, and building up his arm, Giolito should get better. His command through the first five innings was remarkable considering his brief amount of prep time.
Gavin Sheets
Since signing with the Padres before the 2025 season, Gavin Sheets has been the power hitter the Padres hoped he would be, in streaks. Always less effective against left-handed pitchers, Sheets has made adjustments during his time with the Padres and continues to improve against righties. Last season his batting average was almost identical between lefties and righties, but his slug against right-handed pitchers was .453 versus .369 against left-handers. He had 17 homers against righties and two versus lefties.
This season, with minimal appearances versus lefties, Sheets is continuing the trend. He is slugging. 596 versus right-handers so far this year (114 at-bats). In 12 at-bats versus lefties, he is slugging .167. Way too small a sample size, but with some of his teammates performing well against left-handed pitching (Miguel Andujar, Luis Campusano) he isn’t going to get many opportunities.
Overall, Sheets has been clutch, with “late and close” hits. He is second behind Xander Bogaerts in RBI; Bogaerts has 23 and Sheets has 21. His nine homeruns lead the team, and his 10 doubles are one behind Andujar.
Sheets was named the National League Player of the Week with these numbers over the Brewers and Mariners series.
Rodolfo Durán
Catcher Rodolfo Durán waited 11 years to get his first chance to play in a major league uniform. With the broken toe suffered by Luis Campusano in the series versus the Giants, Durán was added to the roster and made his first start on May 7 against the Cardinals. He was 0-for-10 before coming to bat in the seventh inning against Seattle on May 16. Durán lined his first hit as a major leaguer into the Padres’ bullpen for his first home run. In his last at-bat in the ninth inning, he was robbed of another home run by a leaping Julio Rodríguez in center field.
Durán will remain with the Padres in place of the injured Campusano, but it is unlikely any other moment will be as memorable as that one for the veteran of four organizations.
A Quiet Assassin
Reliever Bradgley Rodriquez, 22, graduated from the Padres prospect list this month. He appeared in seven games and 7.2 innings for the Padres in 2025 with a 1.17 ERA and nine strikeouts to three walks. In 2026, he has pitched in 19 games (was the opener for two games) and has 22.2 innings under his belt this season. He is on pace to pitch over 80 innings, which would far exceed his 61.1 innings in 2024 in the minors.
It seems likely he will get optioned at some point to give him a break, but the bullpen will be the less for it. His 1.59 ERA includes 18 strikeouts to five walks, and he has allowed no home runs. His effectiveness is only behind Mason Miller and Jason Adam.
Although he has high-leverage stuff, Rodriguez is being brought along carefully. His fastball touches 100 mph, but it is not his best pitch. He has a plus-plus-changeup that he pairs with a slider for 69% of his offerings.
Roster moves and injury updates
General manager A.J. Preller gave an update on the status of Joe Musgrove and Nick Pivetta in an interview with Ben and Woods of 97.3 The Fan on Friday, May 15. Neither is in a throwing program yet, and he suggested that they would not be until June/July.
It was reported by Kevin Acee in his daily newsletter (via manager Craig Stammen) that Luis Campusano is still unable to come off the IL. His broken toe is still too painful, although he is involved in baseball activities.
The last word on Jake Cronenworth was that he had been referred to a neurologist and is recovering from his concussion under medical care. He did not travel with the team on the latest road trip.
Matt Waldron pitched poorly in his start versus the Brewers on May 12 and then came back and pitched two innings of scoreless relief on May 14. He reportedly came in the next day with a sore upper arm and was placed on the 15-day IL when Alek Jacob was called up to provide extra help to the bullpen. Jacob was sent back down when Giolito was activated.
Jhony Brito has started his rehab from his UCL surgery of last year. He started two games with the ACL Padres and then started for Double-A San Antonio on Sunday, May 17. Brito went four innings with no earned runs allowed. He allowed two hits and had a strikeout, although two unearned runs scored.
