1. Contact Hitting
Advantage: Vladimir Guerrero Jr.
Guerrero Jr. excels in batting average (.288) and has a much lower strikeout rate (17.6%), reflecting his superior ability to make consistent contact. His approach gives him a more reliable offensive presence, even during slumps.
Alonso, with a .249 batting average, leans more on his power, often sacrificing contact for impact.
2. Power and Run Production
Advantage: Pete Alonso
Alonso’s 226 home runs and 586 RBIs highlight his elite power and ability to drive in runs. His slugging percentage (.514) underscores his impact in the middle of the lineup.
Guerrero Jr., while not as prolific in power stats (160 HRs, 507 RBIs), balances his offense with better contact and on-base skills.
3. Plate Discipline
Advantage: Vladimir Guerrero Jr.
Guerrero Jr.’s .362 on-base percentage and lower strikeout rate reflect his disciplined approach at the plate. He consistently puts the ball in play and reaches base more often than Alonso.
Alonso’s .339 OBP is solid but doesn’t match Guerrero’s ability to get on base.
4. Defensive Impact
Advantage: Vladimir Guerrero Jr.
- Guerrero Jr. made a significant leap in his defensive game, earning a Gold Glove Award in 2022 as a first baseman. This recognition reflects his ability to not just stabilize the position but contribute defensively at an elite level.

Guerrero’s defensive growth gives him the edge in this category, highlighting his commitment to becoming a more complete player.
