Second Base - Bip Roberts
This was another surprise as the Padres have a pair of guys right now with success and experience at second base in Jake Cronenworth and Ha-Seong Kim not to mention guys like Roberto Alomar and Mark Loretta. However, the numbers are the numbers and Bip Roberts gets the nod here.
Roberts played for San Diego from 1986 to 1995 and put up over 2500 plate appearances with the team. He only hit 20 home runs during that entire time which is kind of impressive really, but he also slashed .298/.361/.387 during his time in San Diego. If he hit for any sort of power, this wouldn't have been close. However, his 12.5 bWAR still edged out the competition.
In second place was Hall of Famer Roberto Alomar who put up 12.2 bWAR in his three seasons with the Padres. Ha-Seong Kim came in third with 11.6 bWAR.
Shortstop - Fernando Tatis Jr.
Fernando Tatis Jr. may no longer be a shortstop, but his previous work at the position and being the offensive force he has been was more than enough to take the crown at shortstop.
From 2019 to present, Fernando has put up 17.6 bWAR thanks to a .291/.363/.577 line with 98 home runs and 67 stolen bases. His suspension for testing positive for a banned substance certainly hurt his numbers and put a stain on his legacy but based purely on production, Tatis Jr. allowed him to secure first place easily.
In second place is Ha-Seong Kim again who seems like he is most certainly on pace to get the nod for this list in the future. Third place did go to Ozzie Smith for his defense-driven 10.9 bWAR from 1978 to 1981.
